Abstract
Objective:
Study on the non-anthraquinone constituents from rhizoma and radix of Rheum sublanceolatum.
Method:
The constituents were isolated through column chromatography and identified on the basis of their physiochemical and spectral data.
Result:
Six non-anthraquinone constituents were isolated and identified as n-octacosanic acid, sitosterol, daucosterol, 2-methyl-5-carboxymethyl-7-hydroxychromone, piceatannol and 6-hydroxymusizin-8-O-beta-D-glucopyranoside.
Conclusion:
All these compounds were firstly isolated from R. sublanceolatum.
