Chemistry

2',5,7- trihydroxy-3.6-dimethoxy flavone-7-O-b-D-galactopyranosyl-[1®4]-O-a-L-rhamnopyranoside is reported from the seeds of Echinops echinatus. 7-hydroxyisoflavone, kaempferol-4'-methylether, kaempferol-7-methylether, myricetin-3-O-a-L-rhamnoside, kaempferol and kaempferol-3-O-a-L-rhamnoside, are reported from the whole plant of Echinops echinatus.

An antiinflammatory active flavanone glycoside 5,7-dihydroxy-8,4'-dimethoxyflavanone-5-O-a-L-rhamnopyranosyl-7-O-b-D-arabinopyranosyl-(1®4)-O-b-D-glucopyranoside A along with a known compound dihydroquercetin-4'-Me ether is also reported from the leaves of Echinops echinatus.

Apigenin, apigenin 7-O-glucoside, and a new acylflavone glucoside named echitin (I) were isolated from Echinops echinatus flowers.
