喙果黑面神化学成分研究

The chemical constituents of Breynia rostrata

摘要: 目的研究大戟科植物喙果黑面神(Breynia rostrata Merr.)的化学成分。方法利用硅胶、凝胶等色谱技术分离纯化化学成分，根据化合物的理化性质和光谱数据进行结构鉴定。结果从喙果黑面神的正丁醇萃取部分分离得到4个化合物，分别鉴定为6-O-甲基丙酰基-α-D-吡喃葡糖(6-O-methylpropanoyl-α-D-glucopyranose，1)；4″-苯酚基-6-O-甲基丙酰基-β-D-吡喃葡糖苷(4″-phenolic-6-O-methylpropanoyl-β-D-glucopyranoside，2)；1-O-没食子酰基-β-D-吡喃葡糖苷(1-O-galloyl-β-D-glucopyranoside，3)；熊果苷(arbutin，4)。结论化合物1和2为新化合物，3和4均为首次从该种植物分离得到。

Abstract: AimTo study the chemical constituents of Breynia rostrata Merr. MethodsChromatography was used to isolate and purify the chemical constituents, their structures were identified by spectral analysis. ResultsFour glycosides were identified as 6-O-methylpropanoyl-α-D-glucopyranoside (1), 4″-phenolic-6-O-methylpropanoyl-β-D-glucopyranoside (2), 1-O-galloyl-β-D-glucopyranoside (3), arbutin (4). ConclusionCompounds 1 and 2 are new compounds; 3 and 4 were isolated from Breynia rostrata Merr. for the first time.
