The present study was designed to investigate the antioxidant activity of aqueous and methanol extracts of Erythrina indica Lam leaves by in vitro methods viz. 1, 1-Diphenyl-2-Picrylhydrazyl, nitric oxide radical scavenging activity, and inhibition of lipid peroxidation by thiobarbituric acid reactive substances (TBARS) method on isolated rat liver tissues. Quantitative analysis of antioxidativ...
Phycobiliprotein-containing water and carotenoid-containing methanolic extracts of three different cyanobacteria, Pseudanabaena sp., Spirulina sp. and Lyngbya sp., were studied for their DPPH scavenging, iso-bolographic studies, and anti-nephrolithe activities. The best EC50 values for DPPH scavenging were in Lyngbya water (LW, 18.78 ± 1.57 mg·mg(-1) DPPH) and Lyngbya methanol (LM, 59.56 ± 37.3...
The antimicrobial activities of chloroform, acetone and two different concentrations of methanol extracts of Ocimum basilicum L. were studied. These extracts were tested in vitro against 10 bacteria and 4 yeasts strains by the disc diffusion method. The results indicated that the methanol extracts of O. basilucum exhibited the antimicrobial activity against tested microorganisms. While the chlo...
abstract stachys is one of the largest genera in the flowering plant family. it is in the subfamily lamioideae (labiatae), spreading and growing in different parts of iran. the purpose of this study was to investigate the chemical properties of stachyslavandulifolia as well as the essence, ethanol and methanol extracts of this plant. it was collected from chulus located in the west of mazandara...
The preliminary phytochemical study and invitro antimicrobial activity of Coriander sativum (Apiaceae) was investigated against some pathogens isolated from patients with infectious diarrhea. The various solvents extract like aqueous, methanol, chloroform, petroleum ether and hexane were screened for antimicrobial activity against Enterotoxigenic E.coli, Enteropathogenic E.coli,, Salmonella typ...
Andrographis alata Nees is an important medicinal plant. The current study was to investigate the antibacterial, antifungal activity and phytochemical analysis of the various leaf and stem extracts of A.alata. Methanol, ethanol, chloroform, acetone and petroleum ether extracts of shade dried plant leaf and stem of A.alata were tested for antibacterial, antifungal and phytochemical screening. Th...
The efficacy of Gomphrenacelosioides extracts in traditional medicine in the treatment of infectious diseases was evaluated by biological assays. The bioactivities of the extracts of this plant were tested against organisms. The ethyl acetate and methanol extracts of the plant displayed inhibition activities on Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli a...
INTRODUCTION The aim of the study was to examine the cytotoxicity and evaluate the antiviral and virucidal activity of methanol and methanol/H(2)O extracts from the herb of Peucedanum salinum. Plants belonging to the genus Peucedanum (Apiaceae family) have been used in traditional medicine for a long time. MATERIAL AND METHODS The examination of the cytotoxicity of the extracts in the concent...
The anti-feedant and growth inhibitory effects of seed extracts of custard apple in hexane, ethyl acetate and methanol were tested against neonate and 7 days old larvae of the Khapra beetle, Trogoderma granarium, using a feeding bioassay. The LC50 values for hexane, ethyl acetate and methanol extracts were 1195.41, 305.36 and 1446.32 ppm for neonate larvae; 5805, 1300 and 5815 ppm for 7 days ol...
The extracts of the leaves and stem bark of anacardium occidentale were screened for phytochemically for the presence of secondary metabolites and for in vitro antibacterial activity. The phytochemical screening revealed the presence of alkaloids and tannins. The methanol and aqueous leaf extracts and the methanol extract of the stem bark were tested against Klebsiella pneumoniae, Staphylococcu...
