title: [Chemical constituents from Paris mairei].
abstract: Twelve compounds were isolated from the rhizome of Paris mairei Lévl by silica gel, Sephadex LH-20 and ODS col-umn chromatographies. The structure elucidation was accomplished by ESI-MS and NMR methods. These compounds were identified as lupeol(1), lup-20(29) -ene-3β-yl octacosanoate(2), palmitic acid(3), glyceryl α-mono-palmitate(4), α-spinasterol(5), diosgenin (6), (25R) diosgenin-3-O-α-L-rhamnopyranosyl (1--> 4) -α-L-rhamnopyranosyl (1 --> 4) - [α-L-rhamnopyranosyl(1 --> 2)] -β-D-glucopyranoside(7), pennogenin(8), pennogenin-3-O-β-D-glucopyranosyl(1 -->3) - [α-L-rhamnopyranosyl(1 --> 2)] -β-D-glucopyranoside(9), flazin(10), calonysterone(11), and isorhamnetin-3-O-β-gentiobioside(12). Compounds 1-5,10-11 were isolated from the genus Paris for the first time, and all compounds were isolated from this plant for the first time.
