| 摘 要： | 目的:研究广西甜茶(Rubus suavissimus S.Lee)叶中的活性成分。方法:利用反复硅胶柱层析的方法对广西甜茶进行分离和纯化,通过IR、MS、NMR等光谱技术和化学方法鉴定化合物的结构。结果:从广西甜茶叶中分离得到2个对映-贝壳杉烯型二萜类化合物,经鉴定化合物Ⅰ为对映-13-羟基-贝壳杉-16-烯-19-羧酸(ent-13-hydrox-y-kauran-16-en-19-oic acid),化合物Ⅱ为对映-贝壳杉-16-烯-19-酸-13-O-β-D-葡萄糖苷(ent-kauran-16-en-19-oic-13-O-β-D-glucoside)。结论:化合物Ⅱ为首次从该植物中分得。

| Abstract: | 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. |
