TWO ALKALOIDS FROM Asparagus cochinchinensis

摘要

The phytochemical investigation of extracts from the roots of Asparagus cochinchinensis yielded a new indole alkaloid dimer, N-methyl-2,2'-ditryptamine (1), and a known β-carboline alkaloid, (-)-(15',35)-1-methyl-1,2,3,4-tetrahydro-p-carboline-3-carboxylic acid (2). Their structures were established on the basis of spectral data, particularly by the use of 1D NMR and several 2D shift-correlated NMR pulse sequences (~1H-~H COSY, HSQC and HMBC).
