红背山麻杆(Alchornea trewioides)为山麻杆属植物,作为传统的中药被用来减轻疾病和身体不适,但它的药效物质基础尚未完全清楚。为了全面掌握红背山麻杆药效物质基础,采用80%丙酮对其新鲜叶进行提取,并利用MCI gel CHP 20P、Sephadex LH-20等色谱柱进行分离共得到9个化合物。这些化合物的结构经氢谱与碳谱比较分析鉴定为鞣花酸(1)、3-O-甲基没食子酸(2)、decarboxyellagic acid(3)、1-O-没食子酰基-β-D-葡萄糖(4)、1,6-二-O-没食子酰基-β-D-葡萄糖(5)、柯里拉京(6)、叶下珠鞣质D(7)、furosonin(8)、老鹳草素(9)。其中化合物2~9均为首次从该属植物中分离得到。
Alchornea trewioides, a plant belonging to the genus Amapium, is used as a traditional Chinese medicine to relieve illnesses and illnesses, but its pharmacodynamic basis has not yet been fully understood. In order to fully understand the pharmacological substance base of Rhizoma Zedoariae, nine fresh compounds were extracted with 80% acetone and separated by MCI gel CHP 20P and Sephadex LH-20. Nine compounds were obtained. The structures of these compounds were identified as ellagic acid (1), 3-O-methyl gallic acid (2), decarboxyellagic acid (3), 1-O- galloyl-β-D- Glucose (4), 1,6-di-O-galloyl-β-D-glucose (5), Corilagin (6), Phyllanthus annuus D (7), furosonin (8) Prime (9). Compounds 2 to 9 were isolated from this genus for the first time.
