A new flavonoid glycoside from Trichilia emetica

A new compound, catechin-۳-O-α-L-rhamnopyranosyl (۱→۴) β-D-glucopyranoside was isolated from the ethylacetate soluble fraction of the aqueous extract of the whole seeds of Trichilia emetica (Family: Meliaceae). The structure of this compound was established on the basis of nuclear magnetic resonance (NMR), Infrared (IR) spectroscopy and ultraviolet-visible (UV-vis) spectrophotometry. The compound was also subjected to antimicrobial activity and brine shrimp lethality bioassay. The pure compound showed either no or reduced activity against microorganisms tested, it also showed no cytotoxicity.
