OBJECTIVE
To study the bioactive constituents from leaves of Rubus suavissimus S. Lee.
METHODS
Column chromatography with silic gel was employed to isolate and purify the constituents. Their structures were elucidated by means of IR, MS, NMR and chemical methods respectively.
RESULTS
Two consituents were obtained, which were elucidated as ent-13-hydroxy-kauran-16-en-19-oic acid (I), ent-kaura-16-en-19-oic-13-O-beta-D-glucoside (II), respectively.
CONCLUSION
Compound II was seperated from Rubus suavissimus S. Lee for the first time.
目的
研究甜茶（Rubus suavissimus S. Lee）叶中的生物活性成分。
方法
采用硅胶柱色谱法分离纯化成分。分别通过红外光谱（IR）、质谱（MS）、核磁共振（NMR）和化学方法阐明其结构。
结果
得到两种成分，分别鉴定为对映-13-羟基-贝壳杉-16-烯-19-酸（I）、对映-贝壳杉-16-烯-19-酸-13-O-β-D-葡萄糖苷（II）。
结论
化合物II首次从甜茶中分离得到。
