Formulasi dan Evaluasi Emulgel Ekstrak Rimpang Jeringau (Acorus calamus L.) sebagai anti-acne

Dermatology studies in Indonesia show an increase in acne vulgaris incidents with the highest prevalence in adolescents. Acne topical therapy generally contains retinoids. However, this therapeutic option has drawbacks, namely burning sensation, dry skin, erythema, and itching of the skin. Along with people's interest in using natural products, alternative therapies with natural products are increasingly having economic value. One of the natural ingredients that have the potential to be anti-acne is Acorus calamus L. Sweet pea (Acorus calamus L.) is a plant whose leaves and rhizomes are used empirically by the Dayak tribe in Borneo to treat skin diseases. Acorus calamus rhizome ethanol extract can inhibit the growth of Propionibacterium acnes bacteria that predominate in acne inflammation. Acorus calamus rhizome extract in this study was formulated in the form of an emulgel because it effectively delivers hydrophobic active substances. Emulgel is also not greasy but moisturizes the skin. The research aimed to produce an anti-acne emulgel formulation from Acorus calamus extract as a natural raw material that meets the physical stability requirements. The research was conducted at the Phytochemical Laboratory, Pharmaceutical Technology Laboratory, and Microbiology Laboratory of Samarinda School of Health Sciences. The research stages are the preparation of plant extract, phytochemical analysis, preparation of emulgel, evaluation of emulgel, and antibacterial activity assay. The Emulgel formulation was carried out with variations in the concentration of the gelling agent, namely Carbomer 940 0.5% (Formula A), 0.75% (Formula B0, and 1% (Formula C). The results of the physical evaluation showed all formulas met the requirements of the organoleptic test, homogeneity test, pH test, spreadability test, and viscosity test. All formulas have non-Newtonian flow types with plastic properties. The antibacterial test results show that all formulas can inhibit the growth of Propionibacterium acnes bacteria.

Synthesis, Computational Pharmacokinetics Report, Conceptual DFT-Based Calculations and Anti-Acetylcholinesterase Activity of Hydroxyapatite Nanoparticles Derived From Acorus Calamus Plant Extract.

Over the years, Alzheimer’s disease (AD) treatments have been a major focus, culminating in the identification of promising therapeutic targets. A herbal therapy approach has been required by the demand of AD stage-dependent optimal settings. Present study describes the evaluation of anti-acetylcholinesterase (AChE) activity of hydroxyapatite nanoparticles derived from an Acorus calamus rhizome extract (AC-HAp NPs). The structure and morphology of as-prepared (AC-HAp NPs) was confirmed using powder X-ray diffractometer (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HR-TEM). The crystalline nature of as-prepared AC-HAp NPs was evident from XRD pattern. The SEM analysis suggested the spherical nature of the synthesized material with an average diameter between 30 and 50 nm. Further, the TEM and HR-TEM images revealed the shape and size of as-prepared (AC-HAp NPs). The interplanar distance between two lattice fringes was found to be 0.342 nm, which further supported the crystalline nature of the material synthesized. The anti-acetylcholinesterase activity of AC-HAp NPs was greater as compared to that of pure HAp NPs. The mechanistic evaluation of such an activity carried out using in silico studies suggested that the anti-acetylcholinesterase activity of phytoconstituents derived from Acorus calamus rhizome extract was mediated by BNDF, APOE4, PKC-γ, BACE1 and γ-secretase proteins. The global and local descriptors, which are the underpinnings of Conceptual Density Functional Theory (CDFT), have been predicted through the MN12SX/Def2TZVP/H2O model chemistry to help in the comprehension of the chemical reactivity properties of the five ligands considered in this study. With the further objective of analyzing their bioactivity, the CDFT studies are complemented with the estimation of some useful computed pharmacokinetics indices, their predicted biological targets, and the ADMET parameters related to the bioavailability of the five ligands are also reported.

Synthesis of barium ferrite nanoparticles using rhizome extract of Acorus Calamus: Characterization and its efficacy against different plant phytopathogenic fungi

A green technology for producing barium ferrite (BaFe12O19) nanoparticles (BFNP’s) using Acorus Calamus rhizome extract was realized. To confirm the phase of magnetoplumbite structure without any impurities, the method of powder X-ray diffraction was performed using the Rietveld analysis and the FullProf program with the P63/mmc (No. 194) space group. Unit cell parameters were a = 5.8902(2) Å and c = 23.2103(7) Å. According to Scherrer’s calculations, the average crystallite size was from ∼ 32 to ∼ 35 nm. The results of scanning electron microscopy confirmed that synthesized BFNP’s are tightly packed and have an average grain size of ∼ 70 nm. Raman and IR active modes predicted by group theory are observed at ∼ 175 cm−1 and ∼ 677 cm−1, which corresponds to the presence of a spinel structure and trigonal pyramidal position in barium hexaferrite. It was established that the spontaneous magnetization is ∼ 52 emu/g and coercive force is ∼ 440 mT at room temperature. In vitro studies were performed to evaluate the antifungal activity of BFNP’s against various plant pathogenic fungi, namely: Fusarium oxysporum, Alternaria alternata, Colletotrichum gloeosporioides and Marssonina rosae. The antifungal effect of BFNPs was determined for different phytopathogenic fungi at a multiple dose of 200 mg/L, 300 mg/L, 400 mg/L, 500 mg/L and 600 mg/L. The maximum inhibition of mycelial growth (76.67%) was detected at 600 mg/L against the growth of Fusarium oxysoporum mycelium. The data obtained show that BFNP’s synthesized using Acorus Calamus rhizome extract can be applied as a potential antifungal agent.

Comparative physiological tolerance of unicellular and colonial Microcystis aeruginosa to extract from Acorus calamus rhizome

Microcystis blooms and their associated microcystins pose a significant health risk to humans. Microcystis normally occurs as colonies in eutrophic water bodies, and its physiological tolerance to algaecides is dissimilar to that of unicellular forms. However, the differences of physiological response to algaecides between unicellular and colonial Microcystis have been poorly explored. The current study investigated the effects of hexane extract of Acorus calamus rhizome (HEACR) on the physiological and photosynthetic mechanisms of unicellular and colonial M. aeruginosa in the laboratory. We analyzed the cell density, reactive oxygen species (ROS) level, malonaldehyde (MDA) content, photosynthetic pigments, capsular polysaccharide (CPS), and photosystem (PS II) parameters of the two morphological forms of Microcystis. Our results show that HEACR suppresses the growth of both unicellular and colonial M. aeruginosa, increases the intracellular ROS level and cause lipid peroxidation, as well as exerting a detrimental effect on chlorophyll a (chl a) content and photosynthetic efficiency. Almost 100% inhibition was observed for unicellular and colonial M. aeruginosa after 3 d exposure to 50 and 100 mg L−1 HEACR, respectively. The ROS level increase, MDA accumulation, the chl a decrease and carotenoid increase in unicellular M. aeruginosa were all more obvious than that in colonial cells. The fall in photosynthetic efficiency of unicellular M. aeruginosa were also more significant than that of colonial cells. After 3d exposure, the maximum quantum yield of PS II photochemistry (Fv/Fm), effective quantum yield of PS II photochemistry (Fv’/Fm’) and effective quantum yield of photochemical energy conversion in PS II (YII) of unicellular M. aeruginosa was almost totally inhibited by 20 mg L−1 HEACR, while the Fv/Fm, Fv’/Fm’ and YII of colonial M. aeruginosa decreased by 43%, 26% and 66% for 100 mg L−1 of HEACR, respectively. Comparing the two morphological forms of Microcystis, colonies show a greater increase in CPS level to more effectively resist the stress of HEACR and to mitigate ROS generation thereby better defending against oxidative damage. Furthermore, colonial M. aeruginosa shows better photoprotection ability than the unicellular form when exposed to HEACR. The colonies also sustain their maximum electron transport rate, increase their tolerance to strong light, and maintain a higher ability to disperse excess energy. These results demonstrated that HEACR can significantly interfere with the growth and physiological processes of both unicellular and colonial M. aeruginosa, but that colonial M. aeruginosa has a greater ability to adjust physiological tolerance to resist the stresses of HEACR.

One step green synthesis of larvicidal, and azo dye degrading antibacterial nanoparticles by response surface methodology

The present study explored the one step extracellular green synthesis of Iron oxide (FexOy) and manganese oxide nanoparticles (MnNPs) using aqueous extract of Acorus calamus rhizome. The organic chemicals including polyphenol compounds responsible for bio-reduction and stabilization from the polyphenol enriched microwave irradiated aqueous extract of Acorus calamus were studied using GC–MS analysis. Further, their synthesis conditions were optimized using response surface methodology (RSM) and central composite design (CCD) using three variables. The green synthesized Iron oxide and Manganese oxide NPs were characterized by UV, FTIR, XRD, TEM and SEM. Results indicated that the Iron oxide NPs and mixture of iron and manganese NPs showed photocatalytic excellent activities in reducing dyes like methylene blue (0.1%) and Congo red (0.25%) at 0.03% NPs. However, Mn NPs showed moderate activity. On a contrary, manganese showed better larvicidal activity compared to Iron oxide NPs against the phytopathogens commonly affecting the vegetable crops. The present finding showed that high mortality rate at 30 μg/ml concentration of manganese NPs was comparatively interesting. In addition, NPs overall had appreciable activity with P. aeruginosa being more sensitive to Iron oxide NPs (22 ± 2 mm zone of inhibition) and manganese NPs (13 ± 2 mm zone of inhibition) and Iron oxide NPs completely inhibited the growth of A. flavus at 40 μg/ml concentration.

Evaluation of Acorus calamus L. rhizome extract as a bio preservative against wood fungal decay

Wood is most preferred structural material throughout the world and is considered as a complex biological composite with ubiquitous nature. Throughout the world there is an immense pressure on primary durable timbers due to their ever increasing demand. To reduce pressure on the primary species like; Teak, Sal and Deodar etc. one has to look for the other lesser known or secondary species as an alternative. Durability of these species can be enhanced with application of different preservatives and for this one of the best approach is to use herbal based ecofriendly preservatives rather than hazardous chemicals. In this study, the antifungal activity of Acorus calamus rhizome extract was tested on less durable local wood species. The results showed that average growth of Polyporus fungus on taken wood samples were retarded up to 69.44% after applying 2% concentration of rhizome extract and act as suitable bio-preservative for non durable wood species.

Acorus calamus rhizome extract mediated biosynthesis of silver nanoparticles and their bactericidal activity against human pathogens.

Silver nanoparticle (AgNP) synthesis and characterization is an area of vast interest due to their broader application in the fields of science and technology and medicine. Plants are an attractive source for AgNP synthesis because of its ability to produce a wide range of secondary metabolites with strong reducing potentials. Thus, the present study describes the synthesis of AgNPs using aqueous rhizome extract of Acorus calamus (sweet flag). The AgNP formation was evaluated at different temperatures, incubation time and concentrations of AgNO3 using Response surface methodology based Box–Behnken design (BBD). The synthesized AgNPs were characterized by UV–Visible spectroscopy, Fourier transform infra-red spectroscopy (FTIR), X-ray diffraction (XRD), and Scanning electron microscopy–energy-dispersive spectroscopy (SEM–EDS). The surface plasmon resonance found at 420 nm confirmed the formation of AgNPs. SEM images reveal that the particles are spherical in nature. The EDS analysis of the AgNPs, using an energy range of 2–4 keV, confirmed the presence of elemental silver without any contamination. The antibacterial activity of synthesized AgNPs was evaluated against the clinical isolates Staphylococcus aureus and Escherichia coli and it was found that bacterial growth was significantly inhibited in a dose dependent manner. The results suggest that the AgNPs from rhizome extract could be used as a potential antibacterial agent for commercial application.

Effects of Acorus calamus Rhizome Extract on the Neuromodulatory System in Restraint Stress Male Rats.

Prolonged exposure to stress mainly affects the cognitive functions of the brain by inducing neuronal damage mediated through oxidative stress. Acorus calamus (AC) has long been used in Indian folk medicine for various central nervous system (CNS) abnormalities. Hence the present study investigates the effect AC on learning and memory in rats. Adult Wistar male rats were subjected to restrained stress for 21 days (6 hr/day) and the animals were concurrently administered AC for 21 days orally. The Hebb-Williams maze and elevated plus maze served as standard behavioural models for testing memory. The rats were sacrificed on 22nd day and the brain homogenate was taken for various biochemical assessments. Sodium potassium ATPase activity and TBARS levels showed a significant decrease in the stress group compared to control. After administration of AC, the activity of Na- K- ATPase and levels of TBARS showed a tendency to revert back to normal. However there was no effect on AOPP levels, even after the treatment, which remained high. The present study shows the preventive action of AC rhizome powder on stress induced cognitive functions and modulatory effect on antioxidants and Na-K-ATPase activity.

Toxicity study of ethanolic extract of Acorus calamus rhizome

Acorus calamus is widely used in traditional medicine in various ailments. However, there is no toxicological information available regarding its safety after exposure. The present study was designed to evaluate potential toxicity of an ethanolic extract of Acorus calamus Linn. rhizomes after acute and chronic administration in Wistar rats. In the acute toxicity study, female Wistar rats were treated with ethanolic extract by oral gavage at dose levels of 175, 550, 1750 and 5000 mg/kg body weight according to OECD 425. Animals were observed periodically during the first 24 h after administration of the extract, and daily thereafter for 14 days. In the chronic toxicity study, the ethanolic extract of Acorus calamus was administered orally at doses of 0, 200, 400 and 600 mg/kg body weight daily for 90 days in Wistar rats. The effects on clinical signs, body weight, food consumption, organ weight, haematology, clinical biochemistry, as well as histology, were studied. No mortality was observed, but clinical signs like abdominal breathing, piloerection and tremors were observed for 30 min in rats dosed with 1750 mg and 5000 mg/kg body weight of extract. No statistical significant data in body weight and feed consumption were observed. Haematological and biochemical analysis showed no marked differences in any of the parameters. Pathologically, neither gross abnormalities nor histopathological changes were observed. The ethanolic extract of A. calamus does not appear to have toxicity on acute and chronic administration in Wistar rats. Key words: Acorus calamus, acute toxicity, chronic toxicity

Anticellular and immunosuppressive properties of ethanolic extract of Acorus calamus rhizome

Modulation of immune response to alleviate disease has been of interest since long. Plant extracts have been widely investigated for possible immunomodulatory properties. We have evaluated the anticellular and immunomodulatory properties of ethanolic extract of Acorus calamus rhizome. This extract inhibited proliferation of mitogen (phytohaemagglutinin; PHA) and antigen (purified protein derivative; PPD)-stimulated human peripheral blood mononuclear cells (PBMCs). In addition, A. calamus extract inhibited growth of several cell lines of mouse and human origin. It also inhibited production of nitric oxide (NO), interleukin-2 (IL-2) and tumor necrosis factor-α (TNF-α). Intracytoplasmic interferon-γ (IFN-γ) and expression of cell surface markers, CD16 and HLA-DR, on human PBMC, were not affected on treatment with A. calamus extract but CD25 expression was down regulated. Our study demonstrates the antiproliferative and immunosuppressive potential of ethanolic extract of A. calamus rhizome in vitro.
