LC/MS characterization of phenolic antioxidants of Brindle berry (Garcinia gummi-gutta (L.) Robson)
Characterisation of antioxidant fraction of the fruit of Garcinia gummi-gutta was done using liquid chromatography mass spectroscopic (LC/MS) analyses. Total poly phenolics and radical scavenging activity of various extracts such as acetone, methanol and hydroalcohol were estimated spectrophotometrically. The active extract was analysed by LC/MS in order to identify the molecular mass and tentative structures of major compounds. Phenolic compounds such as luteolin 7-O-glucuronide, kaempferol 3-O-(6-O-acetyl) glycoside, dicaffeoylquinic acid, apigenein-6-C-pentosyl-8-C-hexoside and p-coumarylquinic acid were identified from hydro alcoholic extract of G. gummi-gutta.
