[Non-anthraquinone constituents from Rheum sublanceolatum C. Y. Cheng et Kao].
OBJECTIVE
Study on the non-anthraquinone constituents from rhizoma and radix of Rheum sublanceolatum.


METHODS
The constituents were isolated through column chromatography and identified on the basis of their physiochemical and spectral data.


RESULTS
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.


CONCLUSIONS
All these compounds were firstly isolated from R. sublanceolatum.
