Abstract:AIM:To investigate the chemical constituents of Sonchus arvensis L.METHODS:Compounds were isolated and purified by various chromatographic techniques,and their structures were elucidated by physicochemical properties and spectroscopic data.RESULTS:Eleven chemical constituents were isolated and identified as ergost-6,22-diene-3β,5α,8α-triol(1),stigmast-5-ene-3β,7α-diol(2),stigmasta-5,22-dien-3β,7β-diol(3),3β,5α,6β-trihydroxy-stigmast-7,22-diene(4),stigmast-6β-hydroxy-4,22-diene-3-one(5),β-sitosterol(6),daucosterol(7),isoscopoletin(8),aesculetin(9),emodin(10),and apigenin(11).CONCLUSION:Compounds 1-5,8-10 were isolated from the genus Sonchus for the first time,which could be significant from the chemotaxonomic point of view.
Keywords:Sonchus arvensis  Steroid  Phenol  Chemical constituents
