Isoscutellarein 7-glucosyl(1-->2)xyloside from sixteen species of Sideritis.
A new flavone diglycoside isolated from the aerial parts of Sideritis lutoela was characterized as isoscutellarein 7-O-beta-D-glucopyranosyl(1-->2) beta-D-xylopyranoside by means of spectral analyses, applying 2D NMR techniques and NOE experiments. Its presence in 15 other species of Sideritis is described.
