本文对八角莲进行了化学成分研究。采用硅胶、反相硅胶RP-C18及凝胶LH-20柱色谱等方法分离八角莲中的化学成分,应用IR、MS、NMR、2D-NMR等方法进行结构分析。从八角莲95%乙醇提取物中分离鉴定了10个化合物:dysoverine D(1)、dysoverine F(2)、dysoverine A(3)、podoverine A(4)、α-足叶草脂素(5)、芦丁(6)、山柰酚-3-O-β-D-吡喃葡萄糖苷(7)、槲皮素-3-O-β-D-吡喃葡萄糖苷(8)、山柰酚(9)及槲皮素(10)。化合物2为新化合物,化合物1、3~6均为首次从该植物中分离得到。
In this paper, the chemical composition of the octagonal lotus was studied. The chemical constituents of S. japonica were separated by silica gel, reverse phase silica gel RP-C18 and gel LH-20 column chromatography. The structures of the cells were analyzed by IR, MS, NMR and 2D-NMR. Ten compounds were isolated and identified from 95% ethanol extract of Anoectochilus: dysoverine D (1), dysoverine F (2), dysoverine A (3), podoverine A , Rutin (6), kaempferol-3-O-β-D-glucopyranoside (7), quercetin-3-O-β-D-glucopyranoside (8) (9) and quercetin (10). Compound 2 is a new compound, and compounds 1, 3 and 6 are isolated from this plant for the first time.
