Extracts prepared from seeds of Manilkara zapota, Anona squamosa, and Tamarindus indica were screened for their antibacterial activity by disc diffusion and broth dilution methods. Acetone and methanol extracts of T. indica seeds were found active against both gram-positive and gram-negative organisms. MIC values of potent extracts against susceptible organisms ranged from 53-380 μg/mL. Methano...

Fractions prepared from the methanol extract of Buchholzia coriacea stem bark exhibited a high concentration-dependent antibacterial and antifungal activity compared to the standard antibiotics, ampicillin and tioconazole. In the brine shrimp lethality (BSL) assay, the methanol extract was found to be non-toxic with an LC(50) of 1031 microg/ml. The two main compounds present in the most active ...

In this study, the bioactive compounds of Vernonia cinerea have been evaluvated using GC-MS. The chemical compositions of the whole plant methanol extract of Vernonia cinerea were investigated using Perkin-Elmer Gas Chromatography Mass Spectroscopy. GC-MS analysis of V. cinerea plant methanol extract revealed the existence of the GC-MS chromatogram of the seven peaks presented .The major compou...

Antifungal potential of aqueous extracts of forty plants of different families were tested against Fusarium oxysporum f.sp. ciceri causal agent of wilting of chick pea. Among forty plant species tested aqueous extract of Chenopodium ambrosioides has recorded significant antifungal activity against the test fungi. Solvent extracts viz. petroleum ether, benzene, chloroform, and methanol and ethan...

As a measure of testing the medicinal properties of Jatropha curcas, methanol extract obtained from both in vivo leaf and leaf derived callus were subjected to antimicrobial activity against six microorganisms, of the six different concentrations tested, the in vitro leaf callus extracts of at high concentrations (1.0 and 1.2%) inhibited the growth of Staphylococcus aureus and Pseudomonas sp. a...

Objective: Dracocephalum kotschyi (Lamiaceae family) has been usedin traditional medicine for stomach and liver disorders, headache and congestion. In the present study, we have investigated phytochemical properties and antioxidant activities of dichloromethane, ethyl acetate and methanol extracts of D.kotschyi. Material and Methods: Antioxidant activities of extracts were evaluated using the i...

Background: Biofilm formation by Pseudomonas aeruginosa is a serious concern in treatment of diseases and medical industries. Natural products that originate in plants can influence microbial biofilm formation. The effect of ethyl acetate, methanol and water- methanol extracts of Quercus brantii on biofilm formation and biofilm disruption of P. aeruginosa were investigated in this study. Methods...

background: garlic (allium sativum) is known for its anti-bacterial properties, but information on its effects against bacteria species that are important in fish diseases is scarce. objectives: the aim of this research was to use garlic as a natural product to improve the aquatic animal health status so as to compensate the demand for environment-friendly products for sustainable aquaculture. ...

polyamide 6 has been widely used in food packaging applications and also green tea contains amounts of antioxidant compounds. the aim of this study was investigation of green tea effects on properties of polyamide packaging polymer. polyamide 6 was dissolved in methanol which was saturated with calcium chloride. the active packaging film was produced by incorporation of methanol green tea extra...

Despite a long tradition of use in the treatment of mental disorders, Viscum album L. (Ujjral; family – Viscaceae) has not been systematically investigated to validate its traditional claims. The methanol extract of V. album aerial parts, its ethyl acetate fraction (EAF) and 1-butanol fraction (BF) were screened for various neuropharmacological activities. The methanol extract, EAF and BF exhib...
