Objective:
To study the chemical constituents in the medicative part of Sorbaria sorbifolia.
Method:
By means of silica gel re-chromatography and thin layer chromatography, chemical constituents from the CHCl3 and EtOAc extract of the medicative part of S. sorbifolia were studied and their structures were identified by their physical-chemical constants, spectral analysis and comparison with the authorized samples.
Results:
Eight compounds were obtained and identified as follows: noreugenin (I), wogonin (II), 5,7,3',4'-tetrahydroxy-3-methoxyflavone (III), protocatechuic acid (IV), benzoic acid (V), p-hydroxy benzoic acid (VI), emodin (VII) and daucosterol (VIII).
Conclusion:
All of the compounds were isolated from this genus for the first time.
