One new flavonoid, 5,7,8,4'-tetrahydroxy-3-methoxyflavone-8-O-β-d-xylopyranoside (2), along with other four known flavones (1, 3-5) were isolated from the aerial parts of Solanum rostratum. 8-hydroxyflavonoid was isolated from series Androceras for the first time. The structure of the new compound 2 was determined on the basis of spectroscopic techniques, including IR, NMR and HRESI-MS. The chemotaxonomic significance of these compounds was summarised.
从刺萼龙葵地上部分分离得到一种新的黄酮类化合物5,7,8,4'-四羟基-3-甲氧基黄酮-8-O-β-D-吡喃木糖苷（2），以及其他四种已知黄酮（1, 3 - 5）。首次从Androceras系列中分离得到8-羟基黄酮类化合物。基于红外光谱（IR）、核磁共振（NMR）和高分辨电喷雾电离质谱（HRESI-MS）等光谱技术确定了新化合物2的结构。总结了这些化合物的化学分类学意义。
