Abstract:
AIMTo study the bioactive components from Schisandra propinqua (Wall.) Baill var. intermidia A. C. Smith.
METHODSCompounds were separated with a combination of multichromatography. Their chemical structures were determined on the basis of spectral analysis and chemical evidence.
RESULTSSeven compounds were isolated from the leaves of Helicia nilagirica. The structures were elucidated as 6'-O-alpha-L-arabinofuranosylthalictoside (1), 6'-O-beta-D-apiofuranosylthalictoside (2), thalictoside (3), icariside D2 (4), prinsepiol (5), (+)-1-hydroxypinoresinol (6) and (+)-medioresinol (7).
CONCLUSIONTwo compounds are new nitro phenolic glycosides.
