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, (–)-(1S,3S)-1-methyl-1,2,3,4-tetrahydro-β-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–1H COSY, HSQC and HMBC).
