The polyphenolic content, antioxidant and antibacterial activities of the ethanolic extracts of Piper betle leaf obtained from soxhlet (PBSx), sonication (PBSn) and maceration (PBMn) extraction methods were studied. GC–MS analysis was carried out to determine the variation in the phytoconstituents in these extracts. Whereas, thin-layer chromatography (TLC)–bioautography was conducted to localise,...
Bauhinia purpurea leaf was extracted by Soxhlet, ultrasonication and maceration extraction methods using ethanol (99.5%, v/v) to obtain Soxhlet (SBE), ultrasonicated (UBE) and macerated (MBE) B. purpurea leaf extract. The effects of different extracting methods on the polyphenolic content and antioxidant activities using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic...
