Abstract
Five novel 18,19-secooleanane-type triterpene glycosyl esters, namely arjunasides A-E, were isolated from the MeOH extract of the bark of Terminalia arjuna along with nine known oleanane triterpenoids. The structures of the new compounds were determined by spectroscopic analyses including 2D NMR, HRESIMS, and CD spectra.
摘要
从诃子（Terminalia arjuna）树皮的甲醇提取物中分离得到了五种新型 18,19-螺烷型三萜糖苷酯，分别为诃子苷 A-E，同时还分离得到了 9 种已知的齐墩果烷型三萜。通过二维 NMR、高分辨质谱和 CD 光谱等光谱分析确定了这些新化合物的结构。
