Synthesis of zero valent copper/iron nanoparticles using Piper betle leaves for the removal of pharmaceutical contaminant atorvastatin

In this study, bimetallic Cu–Fe nanoparticles were synthesized using the green approach with Piper betle leaves, and the removal efficiency of one of the pharmaceutical compounds, Atorvastatin, was investigated. UV, SEM, FTIR, EDAX, particle size, and zeta potential measurements were used to confirm nanoparticle fabrication. The removal efficiency of Atorvastatin (10 mg/L) by bimetallic Cu–Fe nanoparticles was 67% with a contact time of 30 min at pH 4, the adsorbent dosage of 0.2 g/L, and stirring at 100 rpm. Piper betle bimetallic Cu–Fe nanoparticles have demonstrated excellent stability, reusability, and durability, even after being reused five times. Furthermore, the synthesized bimetallic Cu–Fe nanoparticles demonstrated remarkable antimicrobial properties against gram-negative strains such as Escherichia coli and Klebsiella pneumoniae, gram-positive strains such as Staphylococcus aureus and Bacillus subtilis, and fungi such as Aspergillus niger. In addition, the antioxidant properties of the synthesized bimetallic Cu–Fe nanoparticles were assessed using the DPPH radical scavenging assay. The results indicated that the nanoparticles had good antioxidant activity. Thus, using Piper betle extract to make Cu–Fe nanoparticles made the procedure less expensive, chemical-free, and environmentally friendly, and the synthesized bimetallic Cu–Fe nanoparticles helped remove the pharmaceutical compound Atorvastatin from wastewater.

The Phytochemistry profile of Piper betle extract and its Activity Against Hepatitis C Virus

Hepatitis C virus (HCV) is an RNA virus that is easy to mutate and high risk of resistance. The vaccine for HCV has not been provided yet, and the current treatment is very expensive. To provide alternative and complementary antiviral from plants, this study evaluated the activities of Piper betle (P. betle) against HCV and its combination with existing antiviral drugs, Ribavirin and Simeprevir. The antiviral inhibition was identified by in vitro culture using Huh7it-1 cells and JFH1a HCV. Moreover, the phytochemistry profile was also determined by Thin Layer Chromatography (TLC) and High-Performance Liquid Chromatography (HPLC). The result showed that the ethanol extract of P. betle was possess strong activity with an IC50 value of 0.08 ± 0.028 µg/mL. The mechanism of action revealed the extract dominantly inhibit in the post-entry steps. Furthermore, the combination of P. betle extract with simeprevir increased its anti-HCV activity, however, no effect was observed in the combination with ribavirin. The Western blotting analysis was shown inhibition of NS3 protein levels in a dose-dependent manner. Phytochemistry evaluation was shown for the extract containing flavonoids, polyphenols, and alkaloids. These results suggested that the ethanolic extract of P. betle could be a good candidate for the development or an alternative to anti-HCV drugs.

Chemical and Biological Changes Under Force Degradation and Acceleration Condition of the Combination of Ha-Rak Remedy, Piper betle, and Garcinia mangostana Extracts for Atopic Dermatitis.

Herbal medicine could be an option for atopic dermatitis (AD) treatment for those suffering from global public health. HMB is a new combination of three herb extracts, consisting of the Ha-Rak (HR) remedy extract, Piper betle (PB) extract, and Garcinia mangostana (GM) extract in equal proportions, using Thai traditional medicine theory, that uses a combination of medications that can improve therapeutic efficacy and reduce side effects and toxicity. HMB extract has anti-inflammatory and antiallergic properties, is a component for AD treatment, and tends to develop topical products. Drug registration requires stability data. Results from drug stability testing affect not only the efficacy of the drug but also its safety. The aim of this study was to investigate stability through forced degradation and an accelerated study of extracts. Chemical content analysis and in vitro biological activities such as anti-inflammatory and antiallergic activities determined the effects of all examined samples. Anti-inflammatory and antiallergic effects were assessed by inhibiting nitric oxide synthesis in RAW 264.7 cells and β-hexosaminidase release in RBL-2H3 cells, respectively. High-performance liquid chromatography (HPLC) assessed content indicators. Moisture and temperature hydrolysis had no significant differences in the chemical or biological properties of the HMB. However, the HMB demonstrated sensitivity to alkaline hydrolysis, showed low anti-inflammatory activity, and decreased hydroxychavicol, eugenol, and α-mangostin contents. The contents of the three compounds also decrease with acid hydrolysis. For the accelerated study, anti-inflammatory and antiallergic effects and hydroxychavicol amount were not significantly different after 180 days at 40°C and 75% RH. Therefore, the contents of eugenol and α-mangostin were changed. Eugenol in HMB decreased significantly from the 15th day until the 180th day of storage. In addition, α-mangostin amounts in HMB decreased slightly on 180th day. Fortunately, reducing the two chemicals did not affect anti-inflammatory or antiallergic effects. For stability, combination extract should be stored in a closed container in the refrigerator at a low temperature and protected from light, high temperature, oxygen, and pH. Further HMB development should avoid pH or oxidation processes or components.

Time-kill kinetics of Piper betle L. ethanolic leaf extract on methicillin-sensitive Staphylococcus aureus

Staphylococcus aureus is one of the main pathogens in community and hospital infections that could cause mild skin infections to severe life-threatening bacteremia. Piper betle has shown antibacterial activities against S. aureus but its pharmacodynamics remains unclear despite its widespread availability in many over-the-counter preparations. This study aimed to describe the time-kill kinetics of P. betle extract against methicillin-sensitive Staphylococcus aureus ATCC 29213 (MSSA). Time-kill kinetics were conducted to describe the killing rate of P. betle extract by its effects on MSSA lag time duration, growth rate, and maximum optical density. The surviving colonies at different time-points after exposure to P. betle extract at minimum bactericidal concentration were also determined. Subinhibitory concentrations elucidated its concentration-dependent antibacterial activity by maintaining a trend of increasing lag time, decreasing growth rate, and decreasing maximum optical density as the concentration increases. In particular, concentration at 1250 μg/mL or 0.5 x minimum inhibitory concentration (MIC) showed consistent significant findings across these parameters. Concentrations at MIC and above did not show growth, indicating MSSA growth inhibition or death. P. betle extract’s bactericidal effect started immediately within two (2) hours and was sustained until no growth was observed from the eighth hour and beyond. P. betle extract maintained antibacterial activities against MSSA at subinhibitory concentrations and has also exhibited immediate and sustained bactericidal effect at minimum bactericidal concentration (MBC).

Piper betle extract and its application in bovine teat dipping solution inhibit and eliminate biofilms in bovine mastitis-inducing staphylococci.

Staphylococci, including Staphylococcus aureus, Staphylococcus chromogenes, and Staphylococcus haemolyticus, are significant bacteria that induce bovine mastitis, primarily because they can form biofilms in bovine teat canals. This study aimed to investigate the efficacy of Piper betle extract and a bovine teat dipping solution containing P. betle extract (BSP) against these mastitis-causing staphylococci. BSP was prepared using P. betle extract as the bioactive compound. The antibacterial activity of the plant extract and BSP against the pathogens was investigated using a broth microdilution method. The activity of the extract and BSP against the pathogen biofilms was also determined. A stability test was performed to observe the pH, color, turbidity, homogeneity, precipitation, and separation of BSP stored at 4°C and 25°C for up to 4 weeks. The extract exhibited potent antibacterial activity against S. aureus and S. haemolyticus, with similar values for minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) ranging from 0.03 mg/mL to 0.125 mg/mL. The MIC and MBC values of the extract against S. chromogenes were 0.5-1 mg/mL and 0.5-2 mg/mL, respectively. Moreover, BSP exhibited MIC and MBC values of 12.5-50 v/v against all tested staphylococci isolates. When used at 1/2 and 1/4 × MIC, the extract and BSP significantly inhibited the formation of staphylococcal biofilms (p < 0.05) in the tested strains. The results indicated that treatment with 1/2 × MIC of the extract and BSP resulted in biofilm inhibition ranging from 30%-66% and 19%-39%, respectively. Furthermore, the extract at 16 × MIC eliminated 54%-86% of established mature isolate biofilms, whereas BSP removed 41%-61% of mature biofilm viability. Storage of BSP at 4°C did not change the factors associated with stability from the 1st to 4th week. These findings suggest that BSP may exhibit potential medicinal benefits in inhibiting the growth and biofilm formation of mastitis-inducing staphylococci in bovines.

Bio-engineered, phyto-decorated, multi-form P. betle/ZnO as a potential photocatalytic agent

The rising levels of water contamination worldwide signal a significant need for new materials for its restoration in the coming years. This study provides a novel, simple, cost-effective, and environmentally friendly approach for the production of zinc oxide (ZnO) nanoparticles (NPs) as a promising photocatalyst through the reduction of zinc nitrate hexahydrate using a leaf extract of Piper betle (P. betle). The wurtzite hexagonal structure of ZnO, with a crystallite diameter of 43.44 nm and an energy band gap of 2.97 eV, was seen in P. betle/ZnO. The Fourier transform infrared (FTIR) study showed that phytochemicals from the P. betle extract were present on the surface of P. betle/ZnO. The high-resolution transmission electron microscopy (HRTEM) and field emission scanning electron microscopy (FESEM) analyses revealed the existence of multiple structures scattered evenly (spherical, hexagonal, and rod-shaped). The BET findings indicate that P. betle/ZnO NPs have a highly porous structure with a significant surface area of 97.11 m2/g. The degradation of commercial dye was employed to evaluate the photocatalytic capability of P. betle/ZnO. With ultraviolet radiation, the removal percentage of light green dye might surpass 99% in 80 min with a degradation rate of 2.58 × 10−2 min−1. It was observed that the degradation kinetics follow pseudo-first-order kinetics. P. betle/ZnO is acknowledged as an effective photocatalyst for the treatment of commercial effluent.

Development and characterization of edible films based on flaxseed gum incorporated with Piper betle extract

There has been a shift from use of petroleum-based plastics, causing serious environmental pollution, towards innovative and biodegradable edible packaging. The present study documents the development of composite edible films based on the flaxseed gum (FSG) modified by the incorporation of betel leaf extract (BLE). The films were assessed for physicochemical, mechanical, morphological, thermal, antimicrobial and structural characteristics. Scanning electron microscopy images indicated that the roughness decreased with an increase in BLE concentration. The water vapor permeability of the FSG-BLE films ranged from 4.68 to 1.59 × 10−9 g s− 1 m− 2 Pa− 1, lower than that of the control sample (6.77 × 10−9 g s− 1 m− 2 Pa− 1). The BLE4 (containing 10 % BLE) films had the highest tensile strength of 32.46 MPa compared to the control sample (21.23 MPa). Similarly, EAB and seal strength of the films incorporated with BLE were ameliorated. X-ray diffraction pattern and FTIR illustrated the shift of amorphous to crystalline behavior and a significant interaction among the BLE and FSG functional groups. Furthermore, the thermal stability of the treated films was not affected significantly however, they showed improved antimicrobial activity with the highest diameter of inhibition zone in the BLE4 sample. This study concluded that the FSG-BLE composite films (BLE4 in particular) can be considered as novel packaging material for food conservation coupled with a potential to enhance the shelf life of perishable food products.

Potential natural antimicrobial and antibiofilm properties of Piper betle L. against Staphylococcus pseudintermedius and methicillin-resistant strains

Ethnopharmacological relevancePiper betle L. has potent of antimicrobial activity and is widely used as a traditional remedy to treat skin infections. However, no clear evidence exists concerning antimicrobial and antibiofilm activity against Staphylococcus pseudintermedius and methicillin-resistant S. pseudintermedius (MRSP) opportunistic pathogens that cause wound infections and pyoderma in canines and zoonotic disease. Aim of the studyThe antimicrobial and antibiofilm activities of P. betle extract were assessed against S. pseudintermedius and MRSP strains. Materials and methodsEthanol leaf extract of P. betle was investigated for its antibacterial effect on S. pseudintermedius and MRSP by broth microdilution and time-kill assays. Biofilm inhibition and production assays were performed to evaluate antibiofilm and biofilm eradication effects, respectively. Biofilm-associated gene expression was further studied using real-time polymerase chain reaction (PCR). The possible interaction between IcaA and major compounds in P. betle was analyzed by molecular docking. ResultsThe extract showed minimum inhibitory concentration (MIC) at 250 μg/mL. Growth inhibition of P. betle at 1 MIC against the bacteria was initially observed after treatment for 4 h. All isolates were completely killed after 18 h exposure to the extract. Minimum biofilm inhibitory concentrations (MBICs) of the extract against the tested isolates ranged 1/2 MIC to 1 MIC, while minimum biofilm eradication concentration (MBEC) of P. betle was initialed at 8 MIC. Quantitative inhibition and eradication effects were observed in representative strains. The extract at 1/2 MIC and 1 MIC values inhibited biofilm formation up to 100%, with bacterial biofilm removed at up to 94.21% by 4 MIC of the extract. The extract downregulated the expression of the icaA gene among biofilm-producing isolates. The most abundant compounds, 4-allyl-1,2-diacetoxybenzene and eugenol showed a strong affinity with IcaA protein at −5.65 and −5.31 kcal/mol, respectively. ConclusionsP. betle extract demonstrated the antibacterial, antibiofilm, and biofilm-removal activity against S. pseudintermedius and MRSP. Downregulation of the icaA gene expression and protein interaction were possible modes of action of the extract that impacted biofilm production. This extract showed promise as an alternative treatment for S. pseudintermedius infection, especially drug-resistant and biofilm-associated cases.

Evaluation of antibacterial activity of Piper betle leaf extracts against pathogen of soft rot disease

Soft rot disease commonly occurs in vegetables and fruits. Water-soaked lesions and bad odour are among the symptoms of soft rot disease. Crop production and quality are reduced due to the infection, which causes greater losses. The present study was designed to evaluate the antibacterial effect of Piper betle leaves against a pathogen that causes soft rot diseases. Hexane, chloroform, and methanol were used as extraction solvents, and each extract was prepared with a different concentration (50, 100, 500, 1,000, and 1,500 mg/ml). Each piper betle extract has been shown to inhibit the pathogen responsible for soft rot disease. Piper betle hexane extracts show a better inhibition zone compared to chloroform and methanol extracts. The inhibition zones of Piper betle hexane extracts are 6.5 mm (50 mg/ml), 16 mm (100 mg/ml), 18.5 mm (500 mg/ml), 20.5 mm (1,000 mg/ml), and 11.17 mm (1,500 mg/ml). At 1,000 mg/mL, the inhibition zone of Piper betle hexane extract is 20.5 mm, chloroform is 15.5 mm, and methanol is 16.5 mm. At a concentration of 1,500 mg/ml, the inhibition zone for the three extractions decreases. The findings of this study may contribute to the development of Piper betle leaves as a natural antimicrobial agent.

EFFECTIVENESS OF BETEL LEAF EXTRACT (Piper betle L) AS AN ANTIBACTERIAL AGENT FOR TREATING BACTERIAL INFECTIONS (Aeromonas hydrophila) IN KOI FISH BREEDS

Betel leaf has a long history of use in traditional medicine due to its natural antibacterial properties. This study focuses on the antibacterial effects of betel leaf (Piper betle) extract, particularly against Aeromonas hydrophila infections in koi fish. The research employs an experimental approach using a Completely Randomized Design (CRD) with four treatment groups, each repeated twice. The treatments consist of: a control group (Treatment K) without betel leaf extract, Treatment A with 5 ml of betel leaf extract, Treatment B with 10 ml of betel leaf extract, and Treatment C with 15 ml of betel leaf extract. The results of the study demonstrate the significant efficacy of betel leaf extract in promoting the healing of Aeromonas hydrophila-infected fish. This is evident from observations of reduced wound diameter in fish treated with betel leaf extract. In Treatment A (5 ml dose), noticeable wound diameter reduction begins in the fourth week. Treatment B (10 ml dose) shows similar progress with visible healing in the third week. Treatment C (15 ml dose) exhibits the most promising results, with wound diameter reduction or fading evident as early as the second week. Survival rates are recorded as follows: Treatment K – 50%, Treatment A – 65%, Treatment B – 75%, and Treatment C – 90%. These findings underscore the potential of betel leaf extract as an effective antibacterial remedy in combating Aeromonas hydrophila infections in koi fish.

Enhanced Antibacterial Activity of Piper betle Extract Niosome Serum Gel and Its Irritation Effects

Masks are personal protective equipment essential for COVID-19 prevention, but for the use of masks has led to an increase in the severity of both acne (maskne) and rosacea (mask rosacea). Long-time mask-wearing can increase acne’s flare by modifying the cutaneous facial microenvironment and triggering facial dermatoses. To minimize this, the skin needs to be protected by using an antibacterial product. This study aimed to develop and determine the antibacterial effect of Piper betle extract in niosome serum gel and its irritation effect. 5% Piper betle extract was formulated into a niosome system and incorporated into the serum gel with varying concentrations of 30%, 40%, and 50%. The niosome system was characterized by particle size, Polydispersity Index (PI), zeta potential, and pH value, and then evaluated physicochemical properties for niosome serum gel preparation. Further, the antibacterial effect against Propionibacterium acne, Staphylococcus aureus, and Staphylococcus epidermidis was tested using a well-diffusion test. The preparation stability was evaluated using freeze-thaw methods, and the irritation test was assessed using the HET-CAM (Hen’s Egg Chorioallantoic Membrane) method. The results showed that the preparation has a good physicochemical, while the best inhibition zone diameter was 7,29±0,21; 7,77±0,12; and 8,24±0,40, against P.acne, respectively. However, the results of the stability test of the preparation showed a significant change in the pH but had no irritation effect on CAM. It can concluded that the niosome serum gel of Piper betle extract has a potential antibacterial impact for acne, especially against P. acne.&#x0D; Keywords: Piper betle, Niosome serum gel, antibacterial effect, stability, irritation effect

Utilization of Piper betle L. Extract for Inactivating Foodborne Bacterial Biofilms on Pitted and Smooth Stainless Steel Surfaces.

Biofilms are a significant concern in the food industry. The utilization of plant-derived compounds to inactivate biofilms on food contact surfaces has not been widely reported. Also, the increasing negative perception of consumers against synthetic sanitizers has encouraged the hunt for natural compounds as alternatives. Therefore, in this study we evaluated the antimicrobial activities of ethanol extracts, acetone extracts, and essential oils (EOs) of seven culinary herbs against Salmonella enterica serotype Typhimurium and Listeria innocua using the broth microdilution assay. Among all tested extracts and EOs, the ethanol extract of Piper betle L. exhibited the most efficient antimicrobial activities. To evaluate the biofilm inactivation effect, S. Typhimurium and L. innocua biofilms on pitted and smooth stainless steel (SS) coupons were exposed to P. betle ethanol extract (12.5 mg/ml), sodium hypochlorite (NaClO; 200 ppm), hydrogen peroxide (HP; 1100 ppm), and benzalkonium chloride (BKC; 400 ppm) for 15 min. Results showed that, for the untreated controls, higher sessile cell counts were observed on pitted SS versus smooth SS coupons. Overall, biofilm inactivation efficacies of the tested sanitizers followed the trend of P. betle extract ≥ BKC > NaClO > HP. The surface condition of SS did not affect the biofilm inactivation effect of each tested sanitizer. The contact angle results revealed P. betle ethanol extract could increase the surface wettability of SS coupons. This research suggests P. betle extract might be utilized as an alternative sanitizer in food processing facilities.

Investigation of the Antibacterial, Anti-Biofilm, and Antioxidative Effect of Piper betle Leaf Extract against Bacillus gaemokensis MW067143 Isolated from Dental Caries, an In Vitro-In Silico Approach.

Among oral diseases, dental caries is one of the most frequent to affect human health. The current research work aimed to ascertain the antibacterial, anti-biofilm, and antioxidative potential of Piper betle leaf extract against bacteria isolated from dental caries. Analysis for the presence of phytochemical compounds revealed compounds, such as tannins, steroids, phenolic compounds, and alkaloids, which were also confirmed by TLC and FTIR. GC-MS analysis elucidated the presence of 20 phytocompounds, among which were some well-reported bioactive compounds. The chloroform extract of P. betle demonstrated good antibacterial activity (7 mm) and minimum inhibitory concentration (MIC) (100 mg mL-1) against Bacillus gaemokensis MW067143, which was the frequent biofilm producer among isolated bacterial strains. Fractions of the extract were isolated through column chromatography, after which the antibacterial activity was again evaluated. Spirost-8-en-11-one,3-hydroxy(3β,5α,14β,20β,22β,25R), an oxosteroid in nature, was observed to exhibit remarkable antibacterial potential (12 mm) against B. gaemokensis. Bacterial cells treated with P. betle extract had elevated SOD, APOX, POX, and GR activity, while its proteolytic activity against whole bacterial proteins was pronounced with the suppression of several proteins (50, 40, 15, and 10 kDa) in SDS-PAGE. Bacterial cells treated with P. betle extract demonstrated decreased growth, while the extract was also observed to exhibit inhibition of biofilm formation (70.11%) and demolition of established B. gaemokensis biofilms (57.98%). SEM analysis revealed significant changes to bacterial morphology post treatment with P. betle, with cellular disintegration being prominent. In silico network pharmacology analysis elucidated proteins like ESR1 and IL6 to be majorly involved in biological pathways of dental caries, which also interact with the protective ability of P. betle. Gene Ontology (GO) terms and KEGG pathways were also screened using enrichment analysis. Molecular docking demonstrated the highest binding affinity of Spirost-8-en-11-one,3-hydroxy-,(3β,5α,14β,20β,22β,25R) with bacterial proteins FabI (-12 kcal/mol), MurB (-17.1 kcal/mol), and FtsZ (-14.9 kcal/mol). Therefore, it is suggested that P. betle can serve a potentially therapeutic role and could be used in the preparation of herbal formulations for managing bacterial flora.

EVALUATION OF PIPER BETLE L. EXTRACTS AND ITS ANTIVIRULENCE ACTIVITY TOWARDS P. AERUGINOSA

The virulence factor of bacteria such as P. aeruginosa causes severe problems affecting human health and environmental quality. In this study, Piper betle undergoes an extraction process yielding extract to diminish the virulence factor of P. aeruginosa. The efficiency of Piper betle treatment on P. aeruginosa was measured using Pyoverdine assay. The different factors affected the Piper betle extract yield such as leaves to a solvent ratio (1:6 and 1:10), extraction method (maceration and sonication) and different solvents (methanol, ethanol, ethyl acetate and hexane) were tested. Pyoverdine assay illustrates ethyl acetate exhibits the lowest peak (OD630 = 0.2320) compared to methanol, ethanol and hexane due to the presence of a bioactive compound reducing the virulence factor. The ratio of 1:10 has a higher yield of 4.53±0.05 g and the ratio of 1:6 yields 2.86±0.05 g of extracts because of a better contact area. Maceration with agitation indicated the highest yield of 0.5210±0.05 g followed by maceration without agitation at 0.2660±0.05 g and 0.2792±0.05 g for sonication. The yield of Piper betle with different solvents showed the lowest yield is hexane 0.4741±0.05 g followed by ethyl acetate 2.4975±0.05 g, ethanol 3.7658±0.05 g and methanol 6.3331±0.05 g due to solvent polarity. This study aims to provide insightful knowledge of applied factor affecting Piper betle extracts and the ability of Piper betle as antivirulence and antibacterial agent against P. aeruginosa.

Characterizations and antibacterial activities of passion fruit peel pectin/chitosan composite films incorporated Piper betle L. leaf extract for preservation of purple eggplants

The present study aimed to synthesize biodegradable films based on crosslinked passion fruit peel pectin/chitosan (P/CH) films incorporated with a bioactive extract from Piper betle L. leaf, and investigate their morphological, mechanical, water vapor permeability, optical, and antibacterial properties. The thickness and water vapor permeability of P/CH blend films were proportional to the increasing concentration of Piper betle extract (PB). The tensile strength of P/CH/PB films was significantly reduced at 42.89% compared to the P/CH films. The morphological characterization affirmed that resultant blend films showed a well-organized homogeneous structure with no cracks. Moreover, the antibacterial activities against Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus cereus, and Klebsiella pneumoniae increased with the increased concentration of PB in the obtained films. Our results demonstrated that P/CH/PB blend films could be potentially used for food packaging applications.

Piper betle as bio-pesticides for house flies (musca domestica)

Piper betle is a native Indonesian vines with essential oil composition consisting of phenol compounds and phenolic derivatives of propenyl, eugenol, carvacrol, chavicol, cavibetol, alylpirokatekol, cavibetol acetate, alylpirokatekol acetate, cineol, estragole, methylene, p-cyan sesquiterpenes, and flavonoid compounds; which works as a nerve poison and results in the rapid death of insects. The study used a Factorial design with CRD Structure, 2 replications. It aims to determine the effect of Piper betle leaf extract on the death of Musca domestica, at 6 variations of concentration (0%, 5%, 10%, 15%, 20%, and 25%) and 4 variations of contact time (15, 30, 60, and 120 minutes). The research subject was Musca domestica aged 5 days which was developed from residential areas, with a total of 10 treatments each. The analysis technique uses ANOVA with SAS 9.4. The research proves that Piper betle can be used as an alternative bio-pesticides to Musca domestica. The influencing variables are the concentration of Piper betle extract (P-value &lt;0,000), contact time (P-value &lt;0,000), and concentration and contact time interactions (P-value = 0,0007). Concentration shows a very strong association with the death of Musca domestica and all three variables show that the Power of Test is close to 100%.

Bactericidal activity of Piper betle L. extract against antibiotic resistant Salmonella spp. isolated from pig farms in Southern Thailand

Piper betle L. leaves have traditionally been used to treat various infectious diseases and to possess a wide spectrum of pharmacological effects. This study aimed to determine the antibacterial activity of the Piper betle leaf extract against antibiotic resistant Salmonella spp. isolated from pig farms located in Southern Thailand. Of this, 12 Salmonella spp. isolates were isolated from 24 pig fecal samples from 24 pig farms. The isolates were resistant to ampicillin (91.67%), penicillin (91.67%), tetracycline (81.81%), and doxycycline (81.81%). Antibacterial activity of the Piper betle ethanolic leaf extract against Salmonella spp. was carried out by disc diffusion assays, followed by Minimal inhibitory concentration (MIC) and Minimal bactericidal concentration (MBC) determination, as well as Time kill study. Piper betle extract exhibited antibacterial activity against all the isolates and S. Typhimurium with the inhibition zone ranged from 15.11 ± 0.34 to 20.30 ± 0.50 mm as observed by disc diffusion assay. The extract showed bactericidal activity against the isolates with the MIC and MBC values ranging from 0.5-1.0 mg/mL. Furthermore, the extract at 4 × MIC showed the killing activity with the reduction of the pathogen at least 3 logs within 8 h. The information suggests potential medicinal benefits of the Piper betle leaf extract to inhibit the growth of antibiotic resistant Salmonella spp. isolated from pig farms.

Mupirocin-Loaded Chitosan Microspheres Embedded in Piper betle Extract Containing Collagen Scaffold Accelerate Wound Healing Activity.

This study reports the formulation of mupirocin-loaded chitosan microspheres embedded in Piper betle extract containing collagen scaffold as combinational drug delivery for improved wound healing. Selection of chitosan type (molecular weight and degree of deacetylation) was carried out based on their antibacterial efficacy. The low molecular weight chitosan was selected owing to the highest antibacterial action against gram-positive as well as gram-negative bacteria. Low molecular weight chitosan-microspheres showed spherical shape with largely smooth surface morphology, 11.81% of mupirocin loading, and its controlled release profile. The XRD, DSC thermograms, and FT-IR spectral analysis revealed the mupirocin loaded in molecularly dispersed or in amorphous form, and having no chemical interactions with the chitosan matrix, respectively. The in vivo study indicates potential effect of the mupirocin, Piper betle, and chitosan in the collagen scaffold in the wound healing efficiency with approximately 90% wound healing observed at the end of 15 days of study for combinational drug-loaded chitosan microspheres-collagen scaffold-treated group. The histopathology examination further revealed tissue lined by stratified squamous epithelium, collagen deposition, fibroblastic proliferation, and absence of inflammation indicating relatively efficient wound healing once treated with combinational drug-loaded chitosan microspheres containing scaffold.

Inhibition of rice-blast fungus &lt;i&gt;Magnaporthe oryzae&lt;/i&gt; by &lt;i&gt;Piper betle&lt;/i&gt; extracts: &lt;i&gt;in vitro&lt;/i&gt; evidence and &lt;i&gt;in silico&lt;/i&gt; prediction

Developing new antimicrobial agents towards Magnaporthe oryzae based on Piper betle extracts is practicable if an inhibition mechanism is known. The information for the retrieval was collected from experimental investigations and computational researches on the inhibitability of the plant extract compositions (P1 – P14) towards the fungus trehalose-6-phosphate synthase (PDB-6JBR). Gas chromatography-mass spectrometry characterisation determines 4-Chromanol (P5), 1’-Hydroxychavicol acetate (P6), Eugenol acetate (P7), and 4-Allyl-1,2-diacetoxybenzene (P8) making up the majority of Piper betle extract composition. Bio-assays provide experimental evidence of a total antifungal effect towards M. oryzae. Docking-based simulation confirms the significant static stability of P5-6JBR, P6-6JBR, P7-6JBR, and P8-6JBR. QSARIS analysis exceptionalises bio-compatibility of P5, P6, P7, and P8. The results prove the antifungal potentiality of Piper betle extracts and suggest trehalose-6-phosphate synthase as a promising target for M. oryzae inhibition.
