Abstract :From the overground parts of an endemic Sideritis species, S. stricta, 4 diterpenes, sideridiol (1), isosidol (2), isolinearol (3), and linearol (4); 2 flavonoid glycosides, isoscutellarein 7-O-[6'''-O-acetyl-b -D-allopyranosyl-(1 \to 2)]-b -D-glucopyranoside (5), and isoscutellarein 7-O-[6'''-O-acetyl-b -D-allopyranosyl-(1 \to 2)]-6''-O-acetyl-b -D-glucopyranoside (6); a methoxyflavone, xanthomicrol (7); and a phenylethanoid glycoside, verbascoside (=acteoside) (8) were isolated. The structures of the isolated compounds were established based on spectroscopic evidence (UV, IR, 1D- and 2D-NMR, MS).Keywords : Sideritis stricta, diterpenoids, flavonoids, flavonoid glycosides, methoxyflavones, phenylethanoid glycosides
