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