[Chemical constituents in aerial part of Reineckea carnea].

OBJECTIVE: To study the chemical constituents in the aerial part of Reineckea carnea. METHOD: The compounds were isolated by extraction, silica gel, gel, and reversed-phase silica gel coloum chromatography, and high-performance liquid chromatography. The structures were identified by various spectroscopic methods including 1D and 2D NMR spectrum, MS, IR, etc. RESULT: Six compounds were isolated and identified as 1alpha, 3beta-dihydroxy-5beta-pregn-16-en-20-one-3-O-beta-D-glucopyranoside (1), syringaresinol-beta-D-glucoside (2), sophoraflavone B (3), stigmast-5, 22-dien-3-O-beta-D-glucopyranoside (4), daucosterol (5), a-D-glucose (6). CONCLUSION: Compound 1 was a new compound, coumpounds 2-6 were obtained from the plant for the first time.
