Abstract:
AIM To study the chemical constituents from the Stellaria dichotoma L.var.lanceolata Bge and their anti-inflammatory activities.METHODS The 95％ ethnol extract from S.dichotoma was isolated and purified by silica,MCI,C18 prep-HPLC,then the structures of obtained compounds were identified by physicochemical properties and spectral data.Their anti-inflammatory activities were evaluated by LPS induced RAW264.7 inflammatory cell model.RESULTS Ten compounds were isolated and identified as 3-hydroxy-β-carboline (1),taraxacine A (2),1,2,3,4-tetrahydro-1,3,4-trioxo-β-carbo1ine (3),1-acetyl-β-carboline (4),arenarine A (5),arenarine B (6),diisobutyl-phthalate (7),dibutyl-phthalate (8),(z,z,z)-9,12,15-octadecatrienoic acid,methyl ester (9),tricin (10).Compounds 1-6 had stronger anti-inflammatory activities with the IC50 values of 4.79-9.34 μg/mL.CONCLUSION All the compounds are isolated from this plant for the first time.Their stronger anti-inflammatory activities are discovered for the first time.
