Abstract:
OBJECTIVETo study the chemical constituents of Rhododendron seniavinii.
METHODCompounds were isolated from the aqueous extract of the leaves of R. seniavinii by using Sephadex LH-20, ODS open column chromatography and other means. Their structures were elucidated according to spectral data and physiochemical properties.
RESULTThirteen compounds were isolated from R. seniavinii and identified as 5-methoxydehydroconiferyl alcohol (1), dehydroconiferyl alcohol (2), (-)-syringaresinol (3), (-)-lyoniresinol (4), (+)-lyoniresinol 3alpha-O-beta-D-glucopyranoside (5), (-)-lyoniresinol 3alpha-O-beta-D-glucopyranoside (6), 3,4,5-trimethoxyphenyl-1-O-beta-D-glucopyranoside (7), nikoenoside (8), 3,5,7-trihydroxychromone-3-0-alpha-L-rhamnopyranoside (9), 3,4,5-trimethoxyphenol (10), scopoletin (11), scopolin (12) and quercitrin (13).
CONCLUSIONCompounds 1-12 were obtained from this plant for the first time.
