Chemical constituents of the branch of Amoora gigantea Pierre ex. Laness

Abstract

The dried branch of Amoora gigantea Pierre ex. Laness. were extracted by organic solvents. The crude extracts from different fractions were seperated by column chromatography and seven components were obtained. The structures of them were established on the basis of physical properties, chemical properties and spectral evidences. These seven components were identified as a mixture of long chain carboxylic acids, 5alpha-dammara-20(21), 24-diene-3-one, a mixture of steroids (campesterol, stigmasterol and beta-sitosterol), mixture of steroid glycosides (campesterol-3-O-beta-D-glucopyranoside, stigmasterol-3-O-beta-D-glucopyranoside and beta-sitosterol-3-O-beta-D-glucopyranoside), sucrose, myo-inositol and KCl.
