Alkaloids from Rhizome of Menispermum dauricum and Their Anti-inflammatory Activity
摘要
Abstract
Objective:To study the chemical structures and anti-inflammatory activity of alkaloids from Menispermum dauricum.Methods:The dried rhizome of M. dauricum were powdered and percolated with HCl(pH 3.0).The extract was concentrated under reduced pressure after adjusted to pH 7.0 and subjected to alkaline silica gel and ODS column chromatogra-phies to obtain alkaloids portion.The alkaloid-containing portion was purified by preparative HPLC,using MeOH-H2O as the mobile phase.The structures were identified by extensive spectroscopic analyses,including ESIMS and NMR.Results:Ten al-kaloids were isolated from the plant and identified as lakshminine(1),telazoline(2),daurioxoisoporphine A(3),daurioxoi-soporphine B(4),scrodentoside A(5),(-)-1,3,4-dehydrocepharanthine(6),(+)-1,3,4-dehydrocepharanthine-2′β-N-oxide(7),cissampentine A(8),cissampentine B(9),and(-)-pseudocurine(10).Compounds 6,8,9,and 10 exhib-ited anti-inflammatory activities in vitro,with IC50values of 6.0,12.0,8.5,and 9.7 μmol·L-1,respectively. Conclusion:Compounds 1-10 were obtained from the rhizomes of M.dauricum for the first time.关键词
