Studies On The Chemical Constituents Of Duchesnea Indica Andr. Focke

Duchesnea indica Andr.Focke,the entire plant of Duchesnea indica Andr.Focke in Rosaceae,had the effect on alleviating fever and disintoxication.The petroleum ether portion of EtOH extract of this plant showed antineoplastic activities in vitro.Few reports about chemical and active constituents of this plant can be found in literature.Twenty one compounds were isolated by column chromatographic methods using silica gel,ODS,HPLC and Sephadex LH-20.On the basis of chemical evidence and spectral analysis,the structures of fifteen compounds were identified as euscaphic acid(1),arjunic acid(2).P-hydroxy cinnamic acid(3),apigenin(4),kaempferol(5),corosolic acid(6), maslinic acid(7),tomentic acid(8),kaii-ichigeside F1(9),potengriffioside A(10), rosamultin(11),kaempferol-3-O-β-D-glucoside(12),isoquercitrin(13),β-sitosterol(14), and daucostarine(15).Among them,compound 2,3,4,5,10,12 were isolated from this plant for the first time.
