Abstract Iridoids are a class of secondary metabolites found in wide variety plants. typically plants as glycosides, most often to glucose. The genus Stachys L. is one the largest genera Lamiaceae family, containing iridoids. Aim aim this study was isolation and identification iridoids from aerial parts byzantina K. Koch germanica Methods For iridoids, different chromatographic methods (NP-TLC,...

A key criterion for applying hedge accounting under SFAS 133 is the demonstration of hedge effectiveness. Retrospective assessment of hedge effectiveness may reveal hedge ineffectiveness – the extent to which a gain (loss) on the hedging derivative is not offset by a corresponding loss (gain) on the hedged item. SFAS 133 requires that this accounting measure of hedge ineffectiveness be reported...

Stachys genus with medicinal properties and high polymorphic features has been considered oneof the largest genera of Lamiaceae. The aim of this study was to determine the flavonoid patternvariations and flavonoid groups in ten Stachys species belonging to two sections; Fragilicaulis,and Aucheriana. The studied species were collected from natural habitats in Iran and analysedfor their flavonoid...

Stachys, Lamiaceae familyasının en geniş yayılış gösteren cinslerinden birisidir. Bu cinse ait türler biyolojik aktiviteleri ve etnomedikal kullanımları ile bilinmektedir. çalışmada, Stachys macrantha’nın toprak üstü kısımlarının farklı çözücülerle (etanol, metanol etil asetat) elde edilen ekstraktlarının toplam fenolik flavonoid içeriği antioksidan (ABTS, DPPH) enzim inhibisyon (α-amilaz, α-gl...
