Abstract The new natural product gossypetin 8- O -β- D -glucuronide-3-sulphate was isolated as a minor flavonoid constituent from the leaves of Malva sylvestris . The structure was established by chromatographic behaviour and acid hydrolysis yielding gossypetin, glucuronic acid and sulphate and confirmed by 1 H NMR and 13 C NMR spectroscopy.
摘要 从锦葵叶中分离出一种天然产物棉皮素8-O-β-D-glucuronide-3-sulphate,是一种次要的黄酮类成分。该结构是通过色谱行为和酸水解确定的,产生棉黄素、葡萄糖醛酸和硫酸盐,并通过 1 H NMR 和 13 C NMR 光谱证实。
