目的:对蝉翼藤根茎的化学成分进行研究。方法:利用硅胶柱层析和Sephadex LH-20柱等色谱法对蝉翼藤根茎95%乙醇提取物进行分离,通过理化性质和波谱数据对所得化合物进行结构鉴定。结果:从蝉翼藤根茎95%乙醇提取物的二氯甲烷部位中分离了10个酮类化合物,分别鉴定为:1,7-二羟基酮(1)、1,3,8-三羟基-2-甲氧基酮(2)、1,7-二羟基-3,4-二甲氧基酮(3)、1,3,8-三羟基-4-甲氧基酮(4)、7-羟基-1,2-二甲氧基酮(5)、1,3,6-三羟基-2,7-二甲氧基酮(6)、1,4,8-三羟基酮(7)、1,7-二羟基-3-甲氧基酮(8)、1,6-二羟基-7-甲氧基酮(9)、1,8-二羟基-3,4-二甲氧基酮(10)。结论:其中,化合物7~10为首次从该植物中分离得到,同时化合物7~10为首次从该属植物中分离得到。
Objective: To study the chemical constituents of cicadae canellor rhizomes. Methods: The 95% ethanol extract of Rhizome cicadae was isolated by silica gel column chromatography and Sephadex LH-20 column chromatography. The structures of the obtained compounds were identified by physico-chemical properties and spectral data. Results: Ten kaempferol compounds were isolated from the dichloromethane fraction of 95% ethanolic extract of Cicadaemon canense root, which were identified as: 1,7-dihydroxychromanone (1), 1,3,8-tris Hydroxy-2-methoxy-fenchone (2), 1,7-dihydroxy-3,4-dimethoxycholorone (3), 1,3,8-trihydroxy- (4), 7-hydroxy-1,2-dimethoxycholorone (5), 1,3,6-trihydroxy-2,7-dimethoxycholorone (6) (7), 1,7-dihydroxy-3-methoxycholorone (8), 1,6-dihydroxy-7-methoxychondrone (9), 1,8- Hydroxy-3,4-dimethoxycholorone (10). Conclusion: Among them, compounds 7 ~ 10 were isolated from this plant for the first time, while compounds 7 ~ 10 were isolated from this genus for the first time.
