Objective:
To study the chemical constituents from Serissa serissoides DC. roots.
Methods:
Seven compounds were obtained from the 80% ethanol extract of Serissa serissoides roots by repeated column chromatography over silica gel, Sephadex LH-20 and Polyamide. Their structures were identified by analysis of their spectral data and physics character.
Results:
Seven compounds obtained from the plant leaves were identified as: (+)-pinoresinol(1), (-)-syringaresinol( 2), (+)-meduiresinol(3), (-)-olivil(4), beta-sitosterol(5), oleanolic acid(6) and daucosterol(7).
Conclusion:
They are all known compounds. Compound 2 and 4 was obtained from this genus plants for the first time, and compounds 1,3 and 7 as known compounds were obtained from the root of the plant firstly.
