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