title: [Phenolic constituents from Lysimachia patungensis].
abstract: To study the chemical constituents of Lysimachia patungensis Hand.-Mazz., silica gel column chromatography, reverse phase ODS column chromatography, MCI and Sephadex LH-20, were used to separate the 95% EtOH extract of the whole plant of Lysimachia patungensis Hand.-Mazz.. The structures of the isolated compounds have been established on the basis of chemical and NMR spectroscopic evidence as well as ESI-MS in some cases. Twelve phenolic compounds were obtained and identified as quercetin-3, 3'-di- O-alpha-L-rhamnoside (1), myricetrin (2), quercitrin (3), rutin (4), 2-hydroxynaringenin-4'-O-glucopyranoside (5), naringenin 7-O-glucopyranoside (6), liquiritin apioside (7), licochalcone B (8), tetrahydroxymethoxy chalcone (9), methyl-p-coumarate (10), 2, 4, 6-trihydroxy acetophenone-2-O-glucopyranoside (11) and vaccihein A (12). Among them, compound 1 is a new compound, and compounds 5, 11 and 12 are isolated from the genus Lysimachia L. for the first time, and the others are isolated from the plant for the first time.
