从美丽Mitragyna speciosa中分离得到一个新的吲哚生物碱7 β-羟基-7H-mitracilitine（1）和一个新的氧化吲哚生物碱isopeciofoleine（2），以及9个已知的生物碱。本文还首次报道了异山芹叶碱（3）、异黄桐叶碱（4）、佩楠酰巯基乙胺（5）和3-异佩楠酰巯基乙胺（6）的H-1和C-13 NMR谱数据。(C)2013爱思唯尔有限公司保留所有权利。
A new indole alkaloid, 7 beta-hydroxy-7H-mitraciliatine (1) and a new oxindole alkaloid, isospeciofoleine (2) together with nine known alkaloids were isolated from Mitragyna speciosa and characterized by NMR, CD, and MS spectroscopic data analyses. The H-1 and C-13 NMR spectroscopic data of isospeciofoline (3), isorotundifoline (4), paynantheine (5), and 3-isopaynantheine (6) were also reported for the first time. (C) 2013 Elsevier Ltd.
