Description:
A new Carboline alkaloid, Trifiline D ( 1 ) and a new degraded diterpenoid, Trigoxyphin X ( 4 ) were isolated from the roots and stems of Trigonostemon lii . Their structures were elucidated by extensive spectroscopic analyses including 1D- and 2D-NMR techniques. Compound 1 exhibited weak inhibitory activity against MCF-7, A-549, MGC-803 and COLO-205 with IC 50 values ranging from 27.4 to 35.4 μM. This article is protected by copyright. All rights reserved.
