摘要
目的:研究大叶冬青叶的化学成分。方法:采用多种色谱技术从大叶冬青叶中分离纯化化合物,通过波谱学方法鉴定化合物结构。结果:从大叶冬青叶中分离得到10个化合物,分别鉴定为:3β,13β-dihydroxy-urs-11-en-28-oic acid-13-lactone(1)、β-谷甾醇(2)、3-羟基-11-羰基-乌苏烷-12-烯(3)、(20S,24S)-epoxydammarane-3β,25-diol(4)、25-deuteriostigmasterol(5)、α-香树脂醇(6)、foliasalacin A4(7)、23-羟基乌苏酸(8)、反式对羟基肉桂酸(9)、β-胡萝卜苷(10)。结论:其中,化合物1、3~5、7、9为首次从该植物中分离得到。
Objective :To investigate the chemical constituents from the leaves of llex latifolia. Methods :The constituents were iso- lated and purified by various chromatographic techniques. Their structures were identified by UV, IR, MS and NMR spectroscopic analy- sis. Results:Ten compounds were isolated from the leaves of llex latifolia. Their structures were respectively identified as 3/3, 13β-Di- hydroxy-urs-11 -en-28-oic acid-13-1actone ( 1 ) ,β-sitosterol ( 2 ), 3-hydroxy-11 -oxours-12-ene ( 3 ), ( 20S, 24S ) -epoxydammarane-3/3,25- diol ( 4 ), 25-deuteriostigmasterol ( 5 ), a-amyrin ( 6 ), foliasalacin A4 ( 7 ), 23-hydroxyursolic acid ( 8 ), p-coumaric acid ( 9 ), and β-dau- costerol(10). Conclusion:Compounds 1,3 -5,7 and 9 are isolated from this plant for the first time.
