Antioxidant activity of flavonoids from Sideritis raeseri.
Nine 7-o-allosyl glucosides of 5,8-dihydroxy substituted flavones were isolated from a fraction of the methanol extract of the aerial parts of Sideritis raeseri Boiss et Heldr. subsp. raeseri. The… Expand
Essential oil variation of Lavandula stoechas L. ssp. stoechas growing wild in crete (Greece)
A considerable quantitative variation of the essential oils occurred among the different populations, three of them being fenchone/camphor type and one 1,8-cineole/fenchone type and the variation in the quantitative essential oil composition between leaves and inflorescences was significant. Expand
LC-DAD-MS (ESI+) analysis and antioxidant capacity of crocus sativus petal extracts.
Quantitative analysis data obtained thus far have shown that Crocus sativus petals are a rich source of flavonoids, which suggests that the good antioxidant capacity detected in the various fractions of Crocus sitiva petals could be attributed to the presence of flav onoids. Expand
