WEI Yao-yuan. Chemical Constituents from Bergenia scopulosa(Ⅰ)[J]. Chinese journal of experimental traditional medical formulae, 2012, 18(9): 154-156. DOI: 10.13422/j.cnki.syfjx.2012.09.029.
Objective: To study the chemical constituents from Bergenia scopulosa.Method: The constituents were isolated and purified with the use of macroporous adsorption resins
silica gel column chromatography
Sephedex LH-20
re-crystallization.Their structures were identified on the basis of physiochemical properties and special analysis.Result: Twelve compounds were isolated from methanol extracts of Bergenia scopulosa and their structures were identified as: β-sitosterol(1)
daucosterol(2)
(+)-catechin(3)
gallic acid(4)
arbutin(5)
bergenin(6)
4-O-galloylbergenin(7)
11-O-galloylbergenin(8)
pyrocatechol(9)
syringic acid(10)
quercetin(11)
rutin(12).Conclusion: Compounds 8-12 were obtained from this plant for the first time.
