OBJECTIVE
To investigate the chemical constituents from the stems and branches of Sorbaria arborea.
METHODS
The chemical constituents were isolated and purified by silica gel column chromatography, Sephadex LH-20 column chromatography and recrystallization. Their structures were identified by physicochemical properties and spectra analysis.
RESULTS
Ten compounds were isolated and identified as ursolic acid (1), cucurbitacin F (2), (-) -epicatechin (3), daucosterol (4), arbutin (5), 3-O-β-anthemisol (6), 2,6-dimethoxy-p-hydroquinone-4-O-β-D-glucopyranoside (7), lupeol (8), betulin (9) and lup-20 (29) -en-3β, 30-diol (10).
CONCLUSIONS
All the compounds are isolated from this plant for the first time, and compounds 1, 6 - 8 and 10 are obtained from Sorbaria genus for the first time.
