Evaluation of Different Drying Treatments with Respect to Essential Oil Components, Phenolic and Flavonoid Compounds, and Antioxidant Capacity of Ajowan (Trachyspermum ammi L.).

Ajowan (Trachyspermum ammi L.) is considered a valuable spice and medicinal herb. In this study, the essential oil content and composition of the aerial parts of ajowan were investigated under different drying treatments (sun, shade, oven at 45 °C, oven at 65 °C, microwave, and freeze drying). Moreover, the phenolic content, flavonoid content, and antioxidant capacity of samples were also assessed. Fresh samples produced the highest essential oil content (1.05%), followed by those treated under sun (0.7%) and shade drying (0.95%). Based on gas chromatography-mass spectrometry (GC-MS), thirty compounds were determined in which thymol (34.84-83.1%), carvacrol (0.15-32.36%), p-cymene (0.09-13.66%), and γ-terpinene (3.12-22.58%) were the most abundant. Among the drying methods, freeze drying revealed the highest thymol content, followed by drying in a 45 °C oven. The highest TPC (total phenolic content) and TFC (total flavonoid content) were obtained in the fresh sample (38.23 mg TAE g-1 dry weight (DW)) and in the sample oven-dried at 45 °C (7.3 mg QE g-1 DW), respectively. Based on the HPLC results, caffeic acid (18.04-21.32 mg/100 gDW) and ferulic acid (13.102-19.436 mg/100 g DW) were the most abundant phenolic acids, while among flavonoids, rutin constituted the highest amount (10.26-19.88 mg/100 gDW). Overall, freeze drying was the most promising method of drying for preserving the phenolic (TPC) and flavonoid (TFC) compounds and oil components.

Insecticidal Potential of Essential Oils from Ammi visnaga L. and Trachyspermum ammi L. against Sitophilus oryzae (L.) and In Silico Study of Their Major Constituents

There is a high interest in utilizing natural bioactive products derived from plants as a substitute for synthetic chemicals in the industry. This research focuses on the phytochemical composition of essential oils (EOs) of Ammi visnaga L. and Trachyspermum ammi L and their insecticidal activity against Sitophilus oryzae (L.), a common pest found in stored cereals. The EOs were extracted through steam distillation and analyzed using gas chromatography coupled with mass spectrometry (GC-MS). The EOs of A. visnaga consisted of twenty-four components, with Abietadiene (41.23%) being the most abundant, followed by linalool (25.54%) and limonene (19.04%). On the other hand, the EOs of T. ammi consisted of twenty-eight main components, with isothymol being the most abundant (51.88%). The results revealed that the EOs of T. Ammi (DL50 = 0.1 µL EOs/L of air) were more toxic than A. visnaga (0.38 µL EOs/L of air), with the toxicity varying based on doses and exposure periods. To further understand the molecular mechanisms underlying this activity, molecular docking and dynamic simulations were performed using the major chemical constituents of the oils. The simulation results indicated that the major compounds, Abietadiene and isothymol, interact with the catalytic sites of the target proteins, inhibiting acetylcholinesterase and chitin synthase. These interactions form energetically favorable systems that remain stable throughout the molecular dynamic period. This research provides valuable insights into the potential of these EOs as natural insecticides and highlights the importance of molecular modeling in understanding the biological activities of plant-derived compounds.

Clinical and microbial evaluation of mouthwash containing Achyranthes aspera and Trachyspermum ammi: A randomized controlled non-inferiority trial

ObjectivesAchyranthes aspera (Apamarga) and Trachyspermum ammi (Ajwain) have been used in many clinical conditions, and it displays valuable properties as an alternative to Chlorhexidine (CHX) in the management of gingivitis. Therefore, this study aims to assess the effect of Achyranthes aspera and Trachyspermum ammi (AA + TA) based herbal mouthwash, 0.2 % CHX, and placebo mouthwash on gingival health, plaque control and antibacterial activity against specific periodontal pathogens (Porphyromonas gingivalis and Tannerella forsythia) using quantitative real-time PCR (RT-PCR). MethodsThis was a randomized controlled non-inferiority trial involving 108 children with plaque-induced gingivitis who were randomly assigned to three groups of 36 children each: Group A, AA + TA mouthwash; Group B, CHX mouthwash; and Group C, placebo mouthwash. Gingival index and plaque index were recorded at baseline, 7th and 21st day. RT-PCR was employed to determine the bacterial counts of each plaque sample at baseline and after 21 days. ResultsAll three groups exhibited a gradual and significant reduction in both gingival and plaque scores from baseline to days 7 and 21. However, the placebo group did not demonstrate a significant difference in scores between days 7 and 21. Furthermore, a significant reduction in bacterial counts of P. gingivalis and T. forsythia was observed in the groups receiving CHX and AA + TA mouthwash after 21 days of intervention compared to the placebo group. ConclusionAA + TA mouthwash demonstrated non-inferiority in anti-gingivitis and anti-plaque properties compared to CHX, suggesting its potential suitability as an alternative to CHX when used in conjunction with mechanical plaque control measures.

The Impact of Tadbir as a Pre-Application Treatment of Medicinal Plants on Their Chemical Profiles and Biological Activities in Traditional Persian Pharmacy

Based on basic traditional medicine practice, many plants undergo primary treatments to improve their pharmacological characteristics or to attenuate unwanted or unfavorable features of drugs before incorporating them into drug formulations. These treatments are called “Tadbir” in Traditional Persian Medicine (TPM). The purpose of these processes includes but is not limited to eliminating unnecessary compounds, excluding harmful properties such as toxicity and poignancy, and improving their overall natural properties and effectiveness. Here, the effect of vinegar and acetic acid treatment on three herbal specimens, including Carum carvi L. fruits (CC), Trachyspermum ammi (L.) Sprague fruits (TA), and Nigella sativa L. seeds (NS) were investigated. The treated and non-treated samples were subjected to essential oil and methanol extraction. Further, to assess the alterations in the essential oil constituents caused by Tadbir, samples were analyzed by Gas Chromatography/Mass Spectrometry (GC/MS) and HPTLC fingerprinting techniques. Total phenol and flavonoid content and DPPH free radical scavenging activity of methanol extracts were evaluated. As a result of the treatments, TA extracts showed significant rise in phenol and flavonoid contents. Total phenol content increased from 98.50±1.01 in non-treated increased to 181.20±0.27 mg GAE/g Ext. in the vinegar-treated TA fruit extract and total flavonoid showed a rise from 8.97±1.12 to 12.89±0.41 mg QE/g Ext. This may be the reason behind its lower IC50 values in DPPH free radical scavenging assay. Interestingly, Tadbir treatment of TA fruits with 4% acetic acid, lowered the IC50 value from 1019.42±75.65µg/mL in non-treated control to 274.2±17.22 µg/mL; while vinegar caused a lower degree of reduction in IC50 value (369.4±5.54 µg/mL) in DPPH free radical scavenging assay. However, CC fruit extracts, showed a decrease in phenolic content; while demonstrating an increase in flavonoids. Interestingly, phenol and flavonoid contents were significantly enhanced in treated NS seed extracts. The results of all extracts were found significantly different (p<0,05) from each other and the non-treated control. The conclusive results of the present study may partly justify the pre-application of Tadbir treatments of medicinal plants in traditional pharmacy.

Biogenic iron oxide nanoparticles (Fe2O3 NPs) adeptly diminish leaf blight of Rosa chinensis by exhibiting higher expression of RcWRKY29 and increasing antioxidant enzymatic activities

Rose (Rosa chinensis) is subjected to various biotic and abiotic stresses. In this study, rose leaves with blight symptoms were collected and based on microscopic, morphological, and genetic analyses, the disease-causing pathogen was identified as Aspergillus niger. To our knowledge, this is the first report of leaf blight of R. chinensis in Pakistan. To control this disease, iron oxide nanoparticles (Fe2O3 NPs) were synthesized in the seed extract of Trachyspermum ammi. Suitable formation of synthesized Fe2O3 NPs was tested using reliable techniques. Fourier transformed infrared (FTIR) spectrum of Fe2O3 NPs determined the presence of reducing agent like alcohol, alkyl halide and amine on the surface of NPs. X-Ray diffraction (XRD) analysis depicted crystal-like nature and size (41 nm) of NPs, while scanning electron microscopy (SEM) depicted their spherical shape. Sharp Fe and O peaks were observed by energy dispersive X-ray (EDX) analysis. All concentrations of Fe2O3 NPs (0.25, 0.5, 0.75, 1 and 1.5 mg/ mL) inhibited mycelial growth, in vitro and the greatest inhibition (88.9 %) was observed at 1.0 mg/ mL concentration. SEM micrographs showed severe shrinking and structural decomposition of mycelia at this concentration. In pot experiment, Fe2O3 NPs adeptly controlled blight disease of rose leaves by improving various physiological and biochemical attributes and superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) activities. Findings of Real-Time Quantitative Reverse Transcription PCR (qRT-PCR) showed the higher expression of RcWRKY29 by the application of Fe2O3 NPs, depicting its probable role in plant defense mechanism. These results proved that the application of Fe2O3 NPs can efficiently prevent the spread of blight disease.

Trachyspermum ammi, a plant-based antimicrobial agent for paper packaging in e-commerce for consumer safety

This study used a plant-based antimicrobial agent (Trachyspermum ammi or Ajowan essential oil) to develop a water-based coating emulsion with polyvinyl alcohol as a binder. The emulsion was spray-coated onto the packaging paper to achieve antimicrobial properties and prevent disease transmission during the e-commerce supply chain. The coated papers were studied for their morphological, chemical, mechanical, barrier, and antimicrobial behaviors. The presence of Ajowan oil on coated paper was confirmed by infrared spectroscopy and surface morphology. In parallel, the time-bound release of volatile Ajowan oil from the coated papers was demonstrated when stored in a controlled environment using UV–vis spectroscopy. Both bending stiffness and tear strength significantly increased for coated papers due to the presence of polyvinyl alcohol in the coating, whereas the high concentration of oil resulted slight decrease in tensile and burst strength of coated papers. Finally, the antimicrobial activity of coated paper was checked against S. aureus and E. coli at different concentrations of Ajowan oil in coating and was found to be effective for 10 days. The coated papers also showed remarkable antimicrobial activity when tested against all unknown microbes on bare human hands.

Unveiling the chemical profile, synergistic antibacterial and hemolytic effects of Cymbopogon citratus and Tachyspermum ammi leaves

Current study was performed to investigate the antioxidant, synergistic antibacterial and hemolytic potential of aqueous (AC & AT) and ethanolic (EC & ET) extracts of Cymbopogon citratus and Trachyspermum ammi leaves. The investigated extracts were characterized by FT-IR, HPLC, GCMS and ICP analyses. FT-IR data verified the existence of N–H, O–H, C–O, C=O, S=O, C–N, C=N, C–H(aromatic), Si–C and Si–O moieties in extracts. The highest values of TPC (97.09 mg/100g GAE) and TFC (75.76 mg/100gCE) were shown by the ethanolic extract of T. ammi whereas the aqueous extract of C. citratus showed the lowest quantities of TPC (4.07 mg/100g GAE) and TFC (2.43 mg/100g CE). GC-MS analysis showed the existence of 45, 30, 24 and 8 compounds in AC, EC, ET and AT extracts, respectively. The highest concentrations in AC, EC, ET and AT were observed for 3-hydroxy-3-methylbutanoic acid (11.99%), lupeol (23.26%), phytol (15.53%) and phenylmethylsulfonyl fluoride (58.49%). ICP analysis determined the concentration of 26 metals in extracts. AC possessed the highest concentrations of Na, Ca, Mg and K and may find uses as a nutritional/medicinal supplement of these metals. The ethanolic extract of each plant was richer in antioxidant contents; the ethanolic extract of T. ammi being the richest with 69.07% radical scavenging activity relative to BHT (83.54%). Mixtures of plant extracts exhibited higher biofilm inhibitions than their ingredients or ciprofloxacin against S. aureus and E. coli. Hemolytic activities of all the investigated leaf extracts were found in the safe range.

Phytochemical and Invitro Antihelmintic Activity of Aqueous Polyherbal Seed Extract against Pheretima Postuma

The present study was to evaluate the phytochemical screening and anthelmintic activity of aqueous polyherbal seeds extract (APSE) against Pheretima posthuma. The seeds of Coriandrum sativum, Sesamum indicum, Glycine max, Momordica charantiana trachyspermum ammi, was identified and purchased from local market of Nuzvid. APSE was prepared from the dried seeds of five different plants using the solvent water. Initially, APSE was screened for phytochemical constituents by standard methods. Further, antihelmintic study was conducted against Pheretima posthuma, collected from local Vermicomposting Farm, Nuzvid. In the phytochemical screening, APSE showed presence of glycosides, alkaloids, flavonoids, phenols, phytosterols and tannins. In the anthelmintic study, mortality was produced in earth worm populations by APSE. The use of APSE as an anthelmintic was confirmed by using standard method against Pheretima posthuma. The results indicated that the test drug has significant anthelmintic properties. The data were found statistically significant by using one way ANOVA (P< 0.0001). Hence, it can be concluded that the APSE can be used as a novel drug for the treatment of worm infestations.

Selenium nanoparticles induce coumarin metabolism and essential oil production in Trachyspermum ammi under future climate CO2 conditions.

Research on nanoparticles (NPs) and future elevated CO2 (eCO2) is extensive, but the effects of SeNPs on plant growth and secondary metabolism under eCO2 remain uncertain. In this study, we explored the impact of SeNPs and/or eCO2 on the growth, physiology, chemical composition (primary metabolites, coumarins, and essential oils), and antioxidant capacity of Trachyspermum (T.) ammi. The treatment with SeNPs notably improved the biomass and photosynthesis of T. ammi plants, particularly under eCO2 conditions. Plant fresh and dry weights were improved by about 19, 33 and 36% in groups treated by SeNPs, eCO2, and SeNPs + eCO2, respectively. SeNPs + eCO2 induced photosynthesis, consequently enhancing sugar and amino acid levels. Similar to the increase in total sugars, amino acids showed variable enhancements ranging from 6 to 42% upon treatment with SeNPs + eCO2. At the level of the secondary metabolites, SeNPs + eCO2 substantially augmented coumarin biosynthesis and essential oil accumulation. Consistently, there were increases in coumarins and essential oil precursors (shikimic and cinnamic acids) and their biosynthetic enzymes. The enhanced accumulation of coumarins and essential oils resulted in increased overall antioxidant activity, as evidenced by improvements in FRAP, ORAC, TBARS, conjugated dienes, and inhibition % of hemolysis. Conclusively, the application of SeNPs demonstrates significant enhancements in plant growth and metabolism under future CO2 conditions, notably concerning coumarin metabolism and essential oil production of T. ammi.

The Therapeutic Potential of Essential Oils in Managing Inflammatory Skin Conditions: A Scoping Review.

Conventional therapy is commonly used for the treatment of inflammatory skin conditions, but undesirable effects, such as erythema, dryness, skin thinning, and resistance to treatment, may cause poor patient compliance. Therefore, patients may seek complementary treatment with herbal plant products including essential oils (EOs). This scoping review aims to generate a broad overview of the EOs used to treat inflammatory skin conditions, namely, acne vulgaris, dermatitis and eczema, psoriasis, and rosacea, in a clinical setting. The quality, efficacy, and safety of various EOs, as well as the way in which they are prepared, are reviewed, and the potential, as well as the limitations, of EOs for the treatment of inflammatory skin conditions are discussed. Twenty-nine eligible studies (case studies, uncontrolled clinical studies, and randomized clinical studies) on the applications of EOs for inflammatory skin conditions were retrieved from scientific electronic databases (PubMed, Embase, Scopus, and the Cochrane Library). As an initial result, tea tree (Melaleuca alternifolia) oil emerged as the most studied EO. The clinical studies with tea tree oil gel for acne treatment showed an efficacy with fewer adverse reactions compared to conventional treatments. The uncontrolled studies indicated the potential efficacy of ajwain (Trachyspermum ammi) oil, eucalyptus (Eucalyptus globulus) oil, and cedarwood (Cedrus libani) oil in the treatment of acne, but further research is required to reach conclusive evidence. The placebo-controlled studies revealed the positive effects of kānuka (Kunzea ericoides) oil and frankincense (Boswellia spp.) oil in the treatment of psoriasis and eczema. The quality verification of the EO products was inconsistent, with some studies lacking analyses and transparency. The quality limitations of some studies included a small sample size, a short duration, and the absence of a control group. This present review underscores the need for extended, well-designed clinical studies to further assess the efficacy and safety of EOs for treating inflammatory skin conditions with products of assured quality and to further elucidate the mechanisms of action involved.

IN VITRO ANTIOBESITY ACTIVITY OF SOME PLANTS THROUGH A MODIFIED LIPASE INHIBITION ASSAY

The objective of the present study was to evaluate the antiobesity potential of various plant (leaves or seed) extracts through a modified in vitro lipase inhibitory activity assay. Dimethyl sulphoxide (DMSO, negative control or solvent) extracts as cold infusion of leaves and seeds of some plants were studied for lipase inhibitory potential using porcine pancreatic lipase enzyme, p- nitro phenyl acetate and orlistat (as positive control or standard inhibitor). Among the leaves, the Urtica dioica showed the best pancreatic lipase inhibition activity (52.0 %). On the other hand, among the seeds, Trachyspermum ammi showed the highest per cent lipase inhibition (91.68 %). Among six leaves’ and seven seeds’ extract, it was evident that the seeds showed better pancreatic lipase inhibition activity over the leaves in the study. The lipase inhibition was found to be in the range of 34.43 to 91.68 % for the plants in study. DMSO extract of the plants under the study showed significant pancreatic lipase inhibitory activity indicating strong antiobesity activity. Therefore, the plants can be further investigated for the identification and isolation of chief bioactive constituents for developing the lead molecules for obesity treatment.

Antibacterial effects of chitosan-based hydrogels containing Trachyspermum ammi essential oil on pathogens isolated from dogs with otitis externa

BackgroundGrowing antibiotic resistance has made treating otitis externa (OE) increasingly challenging. On the other hand, local antimicrobial treatments, especially those that combine essential oils (EOs) with nanoparticles, tend to be preferred over systemic ones. It was investigated whether Ajwain (Trachyspermum ammi) EO, combined with chitosan nanoparticles modified by cholesterol, could inhibit the growth of bacterial pathogens isolated from OE cases in dogs. In total, 57 dogs with clinical signs of OE were examined and bacteriologically tested. Hydrogels of Chitosan were synthesized by self-assembly and investigated. EO was extracted (Clevenger machine), and its ingredients were checked (GC-MS analysis) and encapsulated in chitosan-cholesterol nanoparticles. Disc-diffusion and broth Micro-dilution (MIC and MBC) examined its antimicrobial and therapeutic properties.ResultsStaphylococcus pseudintermedius (49.3%) was the most common bacteria isolated from OE cases, followed by Pseudomonas aeruginosa (14.7%), Escherichia coli (13.3%), Streptococcus canis (9.3%), Corynebacterium auriscanis (6.7%), Klebsiella pneumoniae (2.7%), Proteus mirabilis (2.7%), and Bacillus cereus (1.3%). The investigation into the antimicrobial properties of Ajwain EO encapsulated in chitosan nanoparticles revealed that it exhibited a more pronounced antimicrobial effect against the pathogens responsible for OE.ConclusionsUsing chitosan nanoparticles encapsulated with EO presents an effective treatment approach for dogs with OE that conventional antimicrobial treatments have not cured. This approach not only enhances antibacterial effects but also reduces the required dosage of antimicrobials, potentially preventing the emergence of antimicrobial resistance.

Synergistic antibacterial effects of Trachyspermum ammi L. essential oil and sodium nitrite in combination on artificially inoculated food models

The addition of carminative essential oils could be an approach for food preservation and would minimize or substitute chemical preservatives. In the present study, essential oils (n=11) namely, Anethum sowa, Cinnamomum zeylanicum, Citrus bergamia, Cymbopogon flexuosus, Cymbopogon martini, Cymbopogon winterianus, Elettaria cardamomum, Mentha arvensis, Ocimum basilicum, Salvia sclarea and Trachyspermum ammi, were screened against Aeromonas hydrophila and Listeria monocytogenes. The largest diameters of zone of inhibition, 19.9 ± 0.33 mm and 21.7 ± 0.58 mm, were exhibited by T. ammi essential oil against Aeromonas hydrophila and Listeria monocytogenes, respectively. Growth inhibition studies for T. ammi essential oil, sodium nitrite and their combinations were also carried out on cucumber, apple, gram flour soup and mutton broth models. The combination of T. ammi essential oil and sodium nitrite depicted synergism and was also effective in reducing the bacterial counts in artificially inoculated food systems.

Trachyspermum copticum aqueous seed extract-derived silver nanoparticles: Exploration of their structural characterization and comparative antibacterial performance against gram-positive and gram-negative bacteria

Abstract In this study, the aqueous seed extract of Trachyspermum copticum was employed to fabricate silver nanoparticles (AgNPs) for their antibacterial performance. The structural characteristics of the phytofabricated AgNPs were investigated using ultraviolet–visible, energy dispersive X-ray, dynamic light scattering, zeta potential, field emission scanning electron microscope, and Fourier transform infrared spectroscopy. Further, the antibacterial effects of AgNPs were evaluated against two standard gram-positive strains of Staphylococcus aureus and Streptococcus pyogenes and two standard gram-negative strains of Escherichia coli and Klebsiella pneumoniae. The findings showed the phytofabrication of spherical-shaped AgNPs with a Z-average diameter of 119.7 nm and the polydispersity index of 0.56. The minimum inhibitory concentration of AgNPs against S. aureus, S. pyogenes, E. coli, and K. pneumoniae strains was 0.25, 1, 0.5, and 0.5 μg·mL−1, respectively. In addition, the minimum bactericidal concentration of these nanoparticles (NPs) against the mentioned strains was 8, 16, 4, and 4 μg·mL−1, respectively. Furthermore, the AgNPs enhanced the generation of reactive oxygen species significantly in all studied bacteria compared to the control (P < 0.05) suggesting an oxidative-associated antibacterial mechanism of AgNPs. Moreover, a dose-dependent cell death was found in all bacterial samples based on flow cytometry analysis. Overall, this study showed a biological approach for the biosynthesis of AgNPs with significant antibacterial effects.
