Structure elucidation of a flavonoid glycoside from the roots of Clerodendrum serratum (L.) Moon, Lamiaceae

Abstract

Apigenin-7-glucoside, C21H20O10 (7-(β-D-glucopyranosyloxy)-5-hydroxy-2-(4-hydroxyphenyl)-4H-1-benzopyran-4-one), was first time isolated from the roots of Clerodendrum serratum (L.) Moon, Lamiaceae. Structure elucidation of the compound was carried out by ¹H NMR and FAB-MS studies.
