Carbazole Alkaloids

The plant Murraya koenigii, commonly known as curry leaf tree is a rich source of carbazole alkaloids. A number of monomeric as well as dimeric carbazoles with C13, C18 and C23 skeleton have been isolated from the plant. In my present work, a new carbazole alkaloid, designated as mumunine, was isolated from the bark of Murraya koenigii (Linn) Spreng, along with a known carbazole alkaloid, viz. mahanimbine. The structure of the new alkaloid 1 was elucidated on the basis of 1D and 2D NMR spectral data analysis. In this paper, the isolation and structure elucidation of the new compound will be discussed in detail.

Methylene Chloride Extract

Re-investigation of the methylene chloride extract of the root of Ferula sinaica gave a sesquiterpene coumarin with a rare carbon skeleton and 3′,9′-di- epi-samarcandin. The structure elucidation was determined by MS; 1H- and 13C- 1D and 2D NMR spectral data.
