    ABSTRACT: To study the chemical constituents of Salsola collina. The compounds were isolated by column chromatography, and their structures were identified by physical and chemical properties and spectral data. Seven compounds were isolated and identified as n-lignoceric acid (1), n-dotriacontanic acid (2), beta-sitosterol (3), 5, 2'-dihydroxy-6, 7-methylenedioxy-isoflavone (4), vanillic acid (5), (-)syringaresinol 4,4'-bis-O-beta-D-glucopyranoside (6), salicylic acid (7). The compounds of 1, 2, 4, 5 and 6 are isolated from the plant for the first time.

    ABSTRACT: To study the chemical constituents of Salsola collina Pall.. Compounds were isolated by silica gel column chromatography. IR, MS, 1HNMR, 13CNMR, HMQC, HMBC, DEPT were used for the structural identification. Two amide alkaloids were obtained. They were identified as N-transferuloyl-3-methyldopamine (I), (10bS)-1,2,3,5,6, 10b-hexahydropyrrolo [2,1-a]-8,9-dihydroxyisoquinoline-3-one (II). Compound I was isolated from this genus for the first time. Compound II is a new compound named salsoline A.

    ABSTRACT: To study the bioactive constituents of the flower of Castanea mollissima Blume. Compounds were isolated and purified by column chromatography of silica gel and TLC. Structures were determined by various spectroscopic data, including IR, 1HNMR and 13CNMR, EIMS, FABMS and HMBC as well as comparison of the data with those reported in literatures. Five compounds were isolated and elucidated as myricetin (I), quercetin (II), gallic acid (III), 4-quinolinone-2-caboxylic acid (IV), (+) -isolariciresinol-9'-O-alpha-L-rhamnoside (V). These compounds were separated from the flower for the first time and compound V is a new compounds, named chestnutlignansoide.

    ABSTRACT: To study the bioactive constituents from the flower of Castanea mollissima Blume. Compounds were isolated and purified by column chromatography on silica gel and polyamide. Structures were determined by various spectroscopic data,including UV, IR, 1H and 13CNMR, EIMS and FABMS, 1H-13C-COSY and HMBC. Two compounds were isolated from the ethyl acetate fraction of 95% ethanol extract and the structures were elucidated as kaempferol-3-O-[6"-(E)-p-coumaroyl]-alpha-D-mannopyranoside (1) and kaempferol-3-O-[6", 4"-di-(E)-p-coumaroyl]-alpha-D-mannopyranoside (2). Compounds 1 and 2 are new compounds, named castanoside A and B respectirely.
