Chemical constituents from Senecio cannabifolius var.integrilifolius(III)

Objective To investigate the chemical constituents from Senecio cannabifoliusvar.integrilifolius(Koidz.) Kitam. Methods Compounds were isolated and purified by various chromatographic techniques such as silica gel,Sephadex LH-20 and RP-18.And their structures were elucidated with physicochemical properties and spectroscopic data.Results Four chemical constituents were isolated and identified as chlorogenic acid(1),ethyl chlorogenate(2),p-hydroxy benzoic acid(3),ethyl-1-hydroxy-4-oxo-2,5-cyclohexadiene-1-acetate(4) respectively.Conclusion Compound 1-4 are isolated from this plant for the first time.
