Abstract:
The chemical constituents of Cinnamomi Ramulus were investigated in this study. Twenty-two compounds were isolated by silica gel, Sephadex LH-20 gel column chromatographies and preparative HPLC and their structures were identified by various spectral analyses as dihydrorosavin(1), rosavin(2), 1-phenyl-propane-1,2,3-triol(3), patchoulol(4), graphostromane B(5),(+)-lyoniresinol-3 a-O-β-D-glucopyranoside(6),(-)-lyoniresinol-3 a-O-β-D-glucopyranoside(7), cinnacaside(8), subaveniumin A(9), 3-phenyl-2-propenyl-6-O-L-arabinopyranosyl-β-glucopyranoside(10), 2-phenylethyl-β-vicianoside(11), cinnacasol(12), [(2R,3S,4S,5R,6R)-6-(benzyloxy)-3,4,5-trihydroxytetrahydro-2H-pyran-2-yl] methyl hydrogen sulfate(13), coniferyl aldehyde(14),(2R,3R)-5,7-dimethoxy-3',4'-methylenedioxyflavan-3-ol(15), cinnacassin L(16), E-cinnamic alcohol(17),(E)-3-(2-methoxyphenyl)-2-propen-1-ol(18), 2-hydroxyphenylpropanol(19), cinnamomulactone(20),(+)-syringaresinol(21) and cinnamomumolide(22), respectively. Among them, 1 is a new compound and 3-7, 9-11, 13, 15, 18 and 19 were isolated from the plant for the first time.
