cytellin and linarin

To study on the chemical constituents of Lobelia chinensis.. The coloumn chromatographic techniques were applied to isolate constituents, and their structures were elucidated by means of spectral data analysis.. Sixteen compounds were isolated and identified as daucosterol (1), diosmetin (2), apigenin (3), chrysoeriol (4), loteolin (5), hesperidin (6), loteolin-7-O-beta-D-glucoside (7), apigenin-7-O-beta-D-glucoside (8), linarin (9), diosmin(10), 5,7-dimethoxy-8- hydroxycoumarin (11), palmitinic acid (12), lacceroic acid (13), stearic acid (14), beta-sitosterol (15), daucosterol (16).. All of these compouds were obtained from L. chinensis for the first time.

To study on the active components of Nardostachys chinensis Batal, the compounds were isolated and purified by chromatographic methods, with their structures identified by spectral analysis and comparison with published data. 9 compounds were obtained and their structures were identified as acaciin, ursolie acid, octacosanol, kanshone A, nardosinonediol, nardosinone, aristolen-9beta-ol, oleanolic acid and beta-sitosterol. Acaciin, ursolie acid and octacosanol were obtained from Nardostachys chinensis Batal. for the first time. Acaciin and ursolie are the active components of antihiotics and anti-inflammatory.
