    Chemical constituents of Paris polyphylla var. yunnanensis[Reference: WebLink]
    Thirteen compounds were obtained from the 30% ethanol eluting fraction of macroporous resin and their structures were elucidated by their spectral data and physicochemical properties,which were identified as calonysterone( 1),glycoside St-J( 2),methyl ester of glycoside St-J( 3),cussonoside B( 4),methyl 3, 4-dihydroxybenzoate( 5),α-ecdysone( 6),20-hydroxyecdysone( 7),pinnatasterone( 8),polyphyllin H( 9),polyphyllin Ⅶ( 10),parisaponin I( 11),Parisyunnanoside B( 12),polyphyllin Ⅱ( 13). Among them,compounds 1- 5 were obtained from the genus Paris for the first time,and 1- 6 were isolated from this plant for the first time.

    Steroidal saponins from the rhizome of Paris polyphylla and their cytotoxic activities.[Pubmed: 19085682 ]
    Two new furostanol saponins and one new spirostanol saponin were isolated from the rhizome of Paris polyphylla Smith var. yunnanensis, together with 18 known steroidal saponins. The structures of the new steroidal saponins were elucidated as 26-O-beta-D-glucopyranosyl-(25R)-5-ene-furost-3 beta, 17 alpha, 22 alpha, 26-tetrol-3-O-alpha-L-arabinofuranosyl-(1-->4)-[alpha-L-rhamnopyranosyl-(1-->2)]-beta-D-glucopyranoside (2, parisyunnanoside A), 26-O-beta-D-glucopyranosyl-(25R)-5, 20 (22)-diene-furost-3 beta, 26-diol-3-O-alpha-L-arabinofuranosyl-(1-->4)-[alpha-L-rhamnopyranosyl-(1-->2)]-beta-D-glucopyranoside (7, Parisyunnanoside B), and (25R)-spirost-5-ene-3 beta, 12 alpha-diol-3-O-alpha-L-rhamnopyranosyl-(1-->4)-alpha-L-rhamnopyranosyl-(1-->4)-[alpha-L-rhamnopyranosyl-(1-->2)]-beta-D-glucopyranoside (13, parisyunnanoside C) by MS and 1 D and 2 D NMR analysis. The isolated compounds were evaluated for their cytotoxicity against HL-60 human promyelocytic leukemia cells. Our results showed that the spirostanol framework of the aglycone and the terminal alpha-L-rhamnopyranosyl with 1-->2 linkage to the sugar chain of saponins at C-3 are essential for their high cytotoxicity, whereas the hydroxy group substitution at C-12 or C-17 of the aglycone causes a reduction in their activity.
