Thin-Layer Chromatography Identification of Paris fargesii Rhizome,Trillium tschonoskii Rhizome,and Paris Rhizome
Paris Saponin Ⅱ,Ⅵ,H were used as reference substances,and the rhizomes of Paris fargesii,Trillium tschonoskii,and Paris(The rhizome of Paris polyphylla Smith var.chinensis(Franch.)Hara and Paris polyphylla Smith var.yunnanensis(Franch.)Hand.-Mazz.)were identified by thin-layer chromatography(TLC).The results showed that the three reference substances had high resolution and clear spots on the silica gel G thin-layer plate with chloroform-methanol-water(15∶5∶1)as the developing agent under the conditions of 20 ℃±2 ℃ and 50％～60％.According to the difference in components,TLC can be used to distinguish Par-idis fargesii rhizome,Trillium tschonoskii rhizome,and Paris rhizome.
