[Swertiapunimarin from Swertia punicea Hemsl].
A new secoiridoid glycoside, swertiapunimarin (I), was isolated from the whole plant of Swertia punicea Hemsl. The structure was elucidated as 6'-O-beta-D-glucopyranosylsweroside on the basis of chemical and spectroscopic analysis. The other seven known compounds were identified as sweroside (II), swertiamarin (III), oleanolic acid (IV), daucosterol (V), beta-sitosterol (VI), 2,3-dihydroxy-1,4-benzodicarboxylic acid (VII) and methylswertianin (VIII).
