Abstract:
From the aerial parts of Solenostemma argel, two monoterpene glucosides have been isolated and identified as 6,7-dihydroxy-dihydrolinalool 3-O-beta-glucopyranoside and 6,7-dihydroxy-dihydrolinalool 7-O-beta-glucopyranoside. A pregnane glucoside was also isolated and assigned as pregn-5-ene-3,14-beta-dihydroxy-7,20-dione 3-O-beta-glucopyranoside together with the known compounds benzyl alcohol O-beta-apiofuranosyl-(1-->6)-beta-glucopyranoside, 2-phenylethyl O-alpha-arabinopyranosyl-(1-->6)-beta-glucopyranoside, astragalin and kaempferol-3-O-alpha-rhamnopyranosyl-(1-->2)-beta-glucopyranoside.
