从杨梅茎中分离到了两个新的五环三萜杨梅素A和B(1和2)，同时分离到了杨梅素、28-羟基-14-taraxeren-3-one、外延蜜梨醇、β -谷甾醇、4-甲基柱头素-7-烯-3-醇、12-hentriacontanol和1-triacontanol 7个已知化合物。通过化学和光谱学方法确定了它们的结构。1和2对几种不同细胞系的细胞毒活性进行了评估。
Two new pentacyclic triterpenoids myricarin A and B (1 and 2) have been isolated from the stems of Myricaria paniculata , together with seven known compounds, myriconal, 28-hydroxy-14-taraxeren-3-one, epi -friedelanol, beta-sitosterol, 4-methyl stigmast-7-en-3-ol, 12-hentriacontanol and 1-triacontanol. Their structures have been established by chemical and spectroscopic methods. Cytotoxic activities of 1 and 2 have been evaluated against several different cell lines.
