潞西山龙眼的化学成分研究

Chemical constituents from the leaf of Helicia tsaii

从山龙眼属植物潞西山龙眼的叶子中分离了6个化合物,利用核磁共振等方法,鉴定为熊果苷(1)、ro-bustaside B(2)、robustaside D(3)、β-谷甾醇(4)、helicide(5)和(E)-(4-羟基苯基)-丙烯酸甲酯(6)。这6个化合物均为首次从该植物中分离得到。

In order to search for the bioactive leading compounds from Helicia tsaii,six compounds were isolated from the leaf of this plant.They were identified as arbutin（1）,robustaside B（2）,robustaside（3）,β-sitosterol（4）,helicide（STHZ 5）and（E）-methyl 3-（4-hydroxyphenyl）acrylate（6）.All the compounds were isolated from this plant for the first time.
