Chemical constituents of Semen Sojae Praeparatum and their proliferation activity on rat osteoblasts / 中国药学杂志

ABSTRACT

OBJECTIVE: To study the chemical constituents and their proliferation activity on rat osteoblasts of Semen Sojae Praeparatum. METHODS: The compounds were isolated by chromatography on silica gel column, MCI and sephadex LH-20 column. Their structures were elucidated by spectral analysis. The proliferation test was performed by using rat osteoblasts with MTT assays in vitro. RESULTS: Twelve compounds were obtained and identified as daidzin(1), daidzein(2), genistein(3), genistin(4), glycitein(5), glycitin(6), apigenin(7), β-sitosterol(8), stigmasterol(9), campesterol(10), syringaldehyde(11), syringic acid(12), respectively. CONCLUSION: Compounds 5-11 are isolated from Semen Sojae Praeparatum for the first time. The five isoflavones show proliferation activity on rat osteoblasts, and aglycones proved to show better activity than glycosides.
