Coumarin Glycoside from Cissus Sicyoides

Abstract

From the aerial parts of Cissus sicyoides , a new coumarin glycoside 5,6,7,8-tetrahydroxycoumarin-5 g -xylopyranoside was obtained together with known coumarin sabandin, two flavonoids kaempferol 3-rhamnoside and quercetin 3-rhamnoside and two steroids, sitosterol and 3 g - O - g - d -glucopyranosylsitosterol. The structure of compounds was elucidated by spectral analyses.
