Phytochemical constituents of the root of Combretum micranthum G. Don (family: Combretaceae)
The root of Combretum micranthum was evaluated phytochemically. β-sitosterol was isolated and characterized from the hexane extract of C. micranthum root. Epicatechin and catechin as penta-acetates; epigallocatechin, gallocatechin and bartogenic acid –28– β – D – glucoside as hexa-acetates were isolated and characterized from the acetylated methanol extract of the root. The structures of the compounds were established by comparing their spectroscopic data (IR, proton, carbon-13, DEPT 90/135) with data published in the literature [1, 2, 3, 4].
