鞭打绣球中苯酚类化合物的研究

On the phenolic compounds from Hemiphragma heterophyllum Wall

利用色谱法从鞭打绣球的95%乙醇提取物的乙酸乙酯部分中分离得到10个苯酚类化合物.根据化合物的理化性质及波谱数据分析,将其确定为:异香草酸(1),5-甲氧基-2-羟基苯甲醛(2),4-羟基-3-甲氧基苯甲醛(3),丁香醛(4),4-羟基苯甲醛(5),3,4-二羟基苯甲酸(6),丁香酸(7),3-甲氧基-5-丙基苯酚(8),阿魏酸(9),阿魏酸甲酯(10).以上所有化合物均为首次从该种植物中分离得到.

Ten phenolic compounds were isolated from 95% ethanol extracts of Hemiphragma heterophyllum by chromatography, spectroscopy technique, and some methods in computational chemistry. The isolates were identified as isovanillic acid ( 1 ), 5-methoxy-2-hydroxy benzaldehyde ( 2 ), 4-hydroxy-3-methoxy benzaldehyde ( 3 ), syringaldehyde ( 4 ), 4-hydroxy-benzaldehyde ( 5 ), 3,4-dihydroxy-benzoic acid ( 6 ), syringic acid ( 7 ), 3-methoxy-5-propylphenol ( 8 ), 4-hydroxy-3-methoxy cinnamic acid ( 9 ) and 4-hydroxy-3-methoxy cinnamic acid methyl ester ( 10 ) based on the detailed spectral analysis. It is very noteworthy that all the compounds were obtained from this plant for the first time.
