美登木属植物中木栓烷型三萜的结构及其13C NMR波谱特征

摘要

卫矛科美登木属(Maytenus)植物因发现具有较强抗肿瘤活性而备受关注，其中木栓烷型三萜是主要活性成分之一，并具有较特征的A环或A/B环均为芳香化结构。该文综述了近年(1995~2013年)来美登木属植物中木栓烷型三萜的结构类型及其13C NMR特征，为这类化合物的结构鉴定和波谱数据归属提供参考。%Maytenus species are shown to have antitumor activity. Friedelane triterpenoid is found to be one of most active components, especially aromatic friedelane triterpenoid with A ring or A/B rings. In this study, the chemical structures and of and 13C NMR characteristics of friedelane triterpenoids from Maytenus reported in the literature from 1995 to 2013 are summarized and reviewed. The findings are potentially useful for structure elucidation and assignment of the spectroscopic signals of this type of compounds.
