摘要
Two new compounds cadin-2-en-1β-ol-1β-D-glucuronopyranoside （1）, guaia-l,7-dien-3β,13-diol-13α-D- glucofuranoside （2） along with three known compounds have been isolated from the culture hairy roots of Catharanthus roseus. Their structures have been elucidated with the help of 500 MHz NMR using 1D and 2D spectral methods： viz： ^1H and ^13C NMR, ^1H-^1H COSY, ^1H-^13C HETCOR and DEPT aided by ELMS, FAB-MS, HR-FABMS and IR spectroscopy.
