Isolation and identification of a new molecule from Curculigo Orchioides (hypoxidaceae)
Abstract The novel compound 2- β -D-glucopyranosylox y-5-hydrox ybenzyl-2’,6’-dimethoxy-3’-hydroxybenzoate, a glycoside of substituted benzyl benzoate isolated from C. orchioides. The molecular formula C 2 2 H 2 6 O 1 2 was deduced from HRFAB-MS m/z 505.1323 [M+Na] + (required 505.1322 for C 22 H 2 6 O 1 2 Na). Assignments of proton and carbon resonances were deduced from analysis of 1 H- 1 H COSY, heteronuclear HMQC, and HMBC 2D chemical shift correlations.
