The different extracts of Hedychium spicatum Buch.-Ham. (Zingiberaceae) were evaluated for antioxidant activity by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and reducing power determination method. Total phenol and total flavonoid content in each extracts were also determined. Gallic acid and ascorbic acid were used as reference standards. They exhibited strong antioxida...
background: considering the wide consumption of some synthetic antioxidants and their probable negative health effects, in this study, the protective effects of satureja hortensis l. extracts in stabilizing soybean oil against oxidation at different concentrations (200 and 400 ppm) were tested. methods: the aerial parts of s. hortensis l. were collected from isfahan province and extracted with ...
The antibacterial activity of the aqueous, ethanol, methanol and petroleum ether Soxhlet extracts of sundried stem bark of Spathodea campanulata P. Beauv. (Bignoniaceae) was investigated by testing the extracts against B. subtilis, E. coli, P. aeruginosa and S. aureus. The minimum inhibitory concentration (MIC) of the methanol extract was determined against the four bacteria strains and C. albi...

Present study was based upon the phytochemical screening, antimicrobial and antithrombotic potential of a traditional herb Spharenthus indicus (commonly called East Indian globe thistle). A range of solvents from non-polar to polar (n-hexane, ethyl acetate, methanol) were used to attained the extract by employing conventional and modern methods of extraction like orbital shaker assisted extract...
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...

Antioxidant activity of Avicenni marina L and Avicennia officinalis L fruit extracts in ethyl acetate, acetone, methanol and ethanol were studied by ABTS, CrO5 and FRAP method. All the extracts possessed significant amount of the antioxidant activity, extracts in methanol and ethanol was demonstrated convincingly higher antioxidant activity by all the three methods. Whereas, the ethyl acetate e...
Quorum sensing controls the virulence determinants in most proteobacteria. In this work, the hexane, chloroform and methanol extracts of an Ayurveda spice, namely clove (Syzygium aromaticum), shown anti-quorum sensing activity. Hexane and methanol extracts of clove inhibited the response of C. violaceum CV026 to exogenously supplied N-hexanoylhomoserine lactone, in turn preventing violacein pro...
