Two new aromatic monoterpenoid glycosides, cruciaside A (2,5- O -β-D-diglucopyranosyl-3-hydroxy- p -cymene) ( 1 ) and cruciaside B (5- O -β-D-glucopyranosyl-2,3-dihydroxy- p -cymene) ( 2 ), were isolated from aerial parts of Cruciata taurica . The structures of the new compounds were determined by spectral and chemical methods. The new compounds seem to be promising as taxonomic markers for C. taurica . [ABSTRACT FROM AUTHOR]

Four phenylpropanoid glycosides lavandulifolioside 1, martynoside 2, verbascoside (=acteoside) 3 and leucosceptoside A 4,were isolated from aerial parts of Sideritis lycia Boiss. et Heldr.(Lamiaceae). Their structures were determined by chromatographic and spectroscopicmethods (UV, IR, [sup 1] H-NMR, [sup 13] C-NMR, FAB-MS). These compoundsand flavonoid glycosides isolated from the same plant in our previously studywere screened for their anti-inflammatory activity using the carrageenan-inducedmouse paw edema test. The active compounds were then investigated for theireffect on gastric ulceration. Although flavonoid glycosides showed higheractivity than the phenylpropanoid glycosides, the gastric ulceration effectof phenylpropanoid glycosides was less than flavonoid glycosides.
