Abstract

The cyclic peptide alkaloid, chamaedrine, was isolated from the roots of Melochia chamaedris (Sterculiaceae), along with four known cyclic peptide alkaloids (adouetine X, frangulaline, scutianine B and scutianine C), and waltherione A, parasorbic acid, propacine, and (-)-epicatequine. Their structures were elucidated on the basis of spectroscopic analysis, especially by 2D NMR ((1)H-(1)H-COSY, NOESY, HMQC, HMBC).

摘要

从肖槿（梧桐科）的根中分离出环状肽生物碱查马德林，以及四种已知的环状肽生物碱（阿杜汀X、弗朗古林、斯库蒂宁B和斯库蒂宁C），还有瓦尔特里酮A、异山梨酸、原阿片碱和（-）-表儿茶喹宁。它们的结构通过光谱分析得以阐明，特别是通过二维核磁共振（（1）H-（1）H-COSY、NOESY、HMQC、HMBC）。
