The oils obtained by hydrodistillation and steam distillation of the aerial parts of Stachys persica Gmel. and Stachys byzantina C. Koch grown in Iran were analyzed by GC/MS. The essential oil obtained by hydrodistillation of the aerial parts of S. persica was characterized by a high amount of non-terpenoid components of which methyllinoleate (27.7%), hexadecanoic acid (9.8%) and 6,10,14-trimet...

Recently a potent anti-inflammatory effect of hydroalcoholic extract of the aerial parts of the sterile stems of Stachys inflata has been reported. This study examined whether hydroalcoholic extract isolated from aerial parts of non-flowering stems of Stachys inflata (standardized to contain 4.5% caffeic acid derivatives) reduce myocardial infarct size arising from coronary artery occlusion (30...

The essential oil obtained from the aerial parts of the Turkish endemism Stachys aleurites (Lamiaceae) has been studied. The main constituents were sesquiterpene hydrocarbons: bcaryophyllene (33.7%), bicyclogermacrene (14.5%) and germacrene D (9.6%). The main monoterpene was a-pinene (8.4%). Some chemotaxonomical considerations have been provided. 2004 Elsevier Ltd. All rights reserved.

This paper investigates hedge fund performance and risk. The empirical evidence indicates that hedge funds differ substantially from traditional investment vehicles such as mutual funds. The funds with watermarks significantly outperform the funds without watermarks. The average hedge fund returns are related positively to incentive fees, the size of the fund, and the lockup period. Hedge funds...

Stachys officinalis L., palustris sylvatica L. (Lamiaceae) are widely used as herbal remedies. In this study, comparative assessment of the phenolic acids, flavonoids, anthocyanin, and tannins content, together with antioxidant activity extracts obtained from flowers, leaves stems was performed. Phenolic acids determined by HPLC method reached highest values in flower extract S. palustris, stem...

As invasive plant species are a major driver of change on oceanic islands, their control is an important challenge for restoration ecology. The post-control recovery of native vegetation is crucial for the treatments to be considered successful, but few studies have evaluated the effects of control measures on both target and non-target species. To investigate the efficiency of manual control o...

The caffeoyl derivatives of Stachys leaves (Labiateae) were identified as chlorogenic acid, verbascoside and stachyoside. The latter compound, reported here for the fist time, was shown to be a verbascoside derivative containing an extra glucose residue attached to C-2, C-3 or C-4 of rhamnose. Cotyledonary leaves of Stachys accumulate high levels (8 —16 ^mol/g dry tissue) o f the three caffeoyl...
