Coumarin glycosides from Cruciata taurica

Two new coumarin glycosides along with two known coumarin glycosides, daphnine and daphnetine glucoside were isolated from aerial parts of Cruciata taurica. The structures of the new compounds were elucidated by spectral methods and chemical means as 7-O-(6'-acetoxy-b-D-glucopyranosyl)- 8-hydroxycoumarin, and 7-O-[6'-O-(3'',4''-dihydroxycinnamoyl)-b-D- glucopyranosyl]-8-hydroxycoumarin. The phylogenetic significance of coumarins in C. taurica was discussed.
