Studies on the Chemical Constituents of Lysimachia paridiformis Franch. var. stenophylla Franch.

Objective To study the chemical constituents of Lysimachia paridiformis Franch.var.stenophylla Franch.Methods Various chromatographic techniques were used to isolate the constituents from the chloroform and water fractions of Lysimachia paridiformis Franch.var.stenophylla Franch.,and their structures were identified by spectral and chemical methods.Results Six compounds were isolated and identified as β-sitosterol(I),Daucosterol(Ⅱ),,Alternariol(Ⅲ),Methyl-2,4-dihydroxybenzoate(Ⅳ),Alternariol monomethyl ether(V),Huazhongilexin(Ⅵ).Conclusion Compounds(Ⅰ)-(V) were obtained from this plant for the first time.
