Many herbal remedies have been employed in various medical systems for treatment and management of different diseases. The plant Oxalis corniculata Linn. has been used in different system of traditional medication for the treatment of diseases and ailments of human beings. β-sitosterol, betulin, 4-hydroxybenzoic acid, ethyl gallate, methoxyflavones, apigenin, and 7-O-β-D-glucopyranoside were previously isolated from the whole plant of Oxalis corniculata.linn. The review reveals that wide ranges of phytochemical constituents have been isolated from the plant like flavanoids, tannins, phytosterols, phenol, glycosides, fatty acids, galacto-glycerolipid and volatile oil. The leaves contain flavonoids, iso vitexine and vitexine-2”- O- beta – D- glucopyrunoside. It is rich source of essential fatty acids like palmitic acid, oleic, linoleic, linolenic and stearic acids. It has been reported that the plant contains anti-inflammatory, anxiolytic, anticonvulsant, antifungal, antiulcer, antinociceptive, anticancer, antidiabetic, hepatoprotective, hypolipedemic, abortificient, antimicrobial and wound healing properties. The current study is therefore reviewed to provide requisite phytochemical and pharmacological detail about the...

Povidone-Iodine Ointment was prepared using polyethylene glycol base by fusion method and the gel was prepared using Poloxamer 407 as a gelling agent by cold process. The different characteristics of povidone-iodine ointment and gel were compared from the results obtained for assay and total, available and complex iodine contents. These values were comparable with marketed formulations. The formulations were tested for wound healing and antimicrobial activity. Wound healing studies show that the time taken for complete wound healing was slightly less for prepared povidone-iodine ointment and gel than the marketed preparations. Antimicrobial activity also found to be almost equal for the different...

In our study, the sample (cheese) was selected for isolation and identification of Lactobacillus species as local probiotic isolate. The strain was subjected to microscopic and macroscopic investigations for probiotic selection. The world health organization criteria (WHO) were applied to all Lactobacillus species against E. coli, P. areoginosa, S. aerus, Chromobacterium, Serratia and A. flavus, antibiotic sensitivity test, acid and bile tolerance test, heamolytic activity. Antimicrobial compound called bacteriocin was partially purified. The Lactobacillus species was identified by 16S rRNA gene sequencing and specific catalase gene was also amplified. Data showed that Lactobacillus plantarum has a high inhibitory activity, tolerant to bile and acid, highly resistant to many antibiotics. Antimicrobial peptide was partially purified, characterized and bacteriocin produced by L. plantarum remained constant activity after heating at 121oC for 10 min. L. plantarum may be an alternative and promising way for eradicating many diseases. L. plantarum produces antimicrobial metabolites can give reasonable assurance of the control of pathogenic microorganisms. Increase the number of food-poisoning patients, the inhibition of the...

In the present study, the endophytic actinomycetes were collected from three medicinal plants Azadiracta indica, Ocimum sanctum and Phyllanthus amarus. Endophytic actinomycetes were isolated using different media like Starch casein agar, Starch casein nitrate agar, Actinomycetes isolation agar and Soyabean agar, while it showed more colonies in Starch casein agar. The endophytic actinomycetes were stained and biochemical tests were performed. Antimicrobial compound was purified from the filtrate by ethanol extraction method. Antagonistic activities of endophytic actinomycetes isolates were tested against bacterial pathogens (Staphylococcus aureus, Streptococcus pyogenes, Klebsiella pneumoniae and Pseudomonas aeruginosa) and the fungi Rhizopus. For the selected isolates antibiotic resistance was checked using various antibiotic discs like Amoxycillin, Penicillin, Rifampicin and Ampicillin. The strains which showed efficient antibacterial activity were selected to study the effect of mutation by physical and chemical method. In this study, UV mutated endophytic actinomycetes increase antibiotic production than non-mutated endophytic Actinomycetes, whereas in chemical mutation it does not increase the antibiotic...

Symphonia globulifera L.f. (Anani) is an arboreal species, which occurs in the Amazon with antimalarial and antimicrobial properties, especially in the treatment of skin inflammations. It is also used as a general tonic and laxative for pregnant women and its sap/latex is used against rheumatism and tumors. The utilization of natural products from plant origin implies in pharmacobotanical quality control, which consist of the technical specifications of the species. Anatomical description of the leaves and petioles of Symphonia globulifera L. f. were performed. Epidermal cells on both sides of the leaves were observed; they are heterodimensional and polygonal. The stomata are anomocytic and were found only on the abaxial surface. The petiole is plan-convex coated with quadrangular cells and thick cutinization. The results are relevant to the anatomical characterization of the species since data on leaf anatomy of S. globulifera are...
