[Compounds from fraction with cardiovascular activity of Chrysanthemum indicum]

In order to investigate the chemical constituents from the fraction with cardiovascular activtiy of Chrysanthemum indicum, the isolation and purification of compounds from this active fraction were performed, and the chemical structures were elucidated by spectral analysis and comparison of the spectral data with those reported in the literature. As a result, twelve compounds were obtained and identified as (2S) -eriodictyol-7-O-beta-D-glucuronide (1), (2S) -eriodictyol-7-O-beta-D-glucoside (2), (2S) -hesperetin-7-O-beta-D-glucuronide (3), luteolin-7-O-beta-D-glucoside (4), luteolin-7-O-beta-D-glucuronide (5), diosmetin-7-O-beta-D-glucuronide (6), quercetin -7-O-beta-D-glucoside (7), (2S)-eriodict-dicaffeoylquinate (8), 3, 5-dicaffeoylquinic acid(9), 3, 5-cis-dicaffeoylquinic acid (10), 1, 5-dicaffeoylquinic acid (11), and 1, 3-dicaffeoylquinic acid (12). The above result indicated that flavonoids were the ma-dicaffeoylquinate (8), 3, 5-dicaffeoylquinic acid (9), 3, 5-cis-dicaffeoylquinic acid (10), 1, 5-dicaffeoylquinic acid (11), and 1, 3-dicaffeoylquinic acid (12). The above result indicated that flavonoids were the major components of the active fraction. Compounds 2, 3, 7, 8 and 10 were obtained from this genus for the first time, and compounds 5, 6, 9, 11, and 12 were first isolated from C. indicum.
