Chemical constituents of acrial part of Bupleunum malconense / 中草药

ABSTRACT

Objective: To investigate the chemical constituents in the dried acrial part of Bupleunum malconense. Methods: Column chromatography, such as silica gel, MCI, and Sephadex LH-20 were used to isolate the compounds. Spectroscopic methods such as 1H-NMR and 13C-NMR were used to elucidate their structures. Results: Eleven compounds were separated and identified as quercetin (1), quercetin-3-O-α-L-arabinofuranoside (2), eriodictyol (3), 3',4',5,7-tetrahydroxy-3-methoxyflavone (4), protocatechuic acid (5), quercetin-3-O-α-L-rhamnopyranoside (6), kaempferol (7), isorhanmetin (8), rutin (9), β-sitosterol (10), and daucosterol (11). Conclusion: All 11 compounds are isolated from the plants in B. malconense for the first time. Compounds 3 and 4 are isolated from the plants in genus Bupleunum L. for the first time.
