Chemical constituents from roots of Psammosilene tunicoides / 中国中药杂志

ABSTRACT

Three compounds, including a new one (1), were isolated from the roots of Psammosilene tunicoides. Based on analysis of NMR data as well as their physical and chemical properties, their structures were elucidated as 3,3'-(4,5-dimethoxynaphthalene-2,7-diyl) bis (1-nitropropan-1-one) (1), alpha-spinasterol-3-O-beta-D-glucopyranoside (2) and alpha-spinasteryl-3-O-beta-D-glucoside-6'-O-palmitate(3). Compounds 2 and 3 were isolated from this genus for the first time.
