Scusalviosides A and B

Scutellaria salviifolia Benth. is an endemic species growing in Turkey that belongs to the family Lamiaceae. As a result of a phytochemical study on the aerial parts of S. salviifolia Benth., two new and 10 known compounds were isolated from the aqueous fraction of methanolic extract. The new compounds are methyl-α-pyrone glucosides, 3,4-dihydroxy-6-methylpyran-2-one 3-O-β -glucopyranoside (=scusalvioside A, 1), and 3,4-dihydroxy-6-methylpyran2-one 3-O-β -(6′ -O-E -caffeoyl) glucopyranoside (=scusalvioside B, 2) with new skeletal structures.
