Abstract
One new 14-membered frangulanine-type cyclopeptide alkaloid, oxyphyl line-A (1) has been isolated from the stem bark of Zizyphus oxyphylla together with the known 13-membered cyclopeptide, nummularine R (2). The structure was established on the basis of spectral studies particularly 2D NMR.
摘要
从酸枣的茎皮中分离出一种新的14元弗兰古宁型环肽生物碱——氧叶碱-A（1），以及已知的13元环肽——钱币树碱R（2）。该结构是基于光谱研究，特别是二维核磁共振确定的。
