Flavonoid and phenolic glycosides from Salvia officinalis

Two novel phenolic glycosides cis-p-coumaric acid 4-O-(2'-O-beta-D-apiofuranosyl)-beta-D-glucopyranoside and trans-p-coumaric acid 4-O-(2'-O-beta-D-apiofuranosyl)-beta-D-glucopyranoside were isolated and identified from Salvia officinalis together with 4-hydroxyacetophenone 4-O-(6'-O-beta-D-apiofuranosyl)-beta-D-glucopyranoside, luteolin 7-O-beta-D-glucoside, 7- and 3'-O-beta-D-glucuronide, 6-hydroxyluteolin 7-O-beta-D-glucoside and 7-O-glucuronide, and 6,8-di-C-beta-D-glucosylapigenin (vicenin-2). The luteolin glucuronides and vicenin-2 were identified as new sage constituents.
