Abstract

A new carbazole alkaloid, designated as murrayakoeninol, was isolated from the leaves of Murraya koenigii (Linn) Spreng, along with four known carbazole alkaloids, viz. mahanimbine, koenimbine, O-methylmurrayamine-A and murrayazolinine and one from the bark viz. girinimbine. The structure of the new alkaloid 1 was elucidated on the basis of 2D NMR spectral analysis and chemical reactions.
