[Chemical Compositions from Stems and Branches of Sorbaria arborea]
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).
Conclusion:
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.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
