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.

Background & Aim: The present study was aimed to evaluate and compare the antibacterial activity of Schrophularia striata Boiss. andStachys schtschegleevii Sosn. Extracts against seven clinical isolates. The test isolates were Streptococcus agalactiae, Enterococcus faecalis, Staphylococcus saprophyticus, E. coli, Klebsiella pneumoniae, Proteus mirabilis an...

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...

      Random samples from asymptomatic leaves and branches of five native medicinal plants: Stachys lavandulifolia, Rumex pulcher, Hypericum scabrum, Starja bachteriarica and Achillea kellalensis were collected from Chaharmahal province of Iran and examined for the presence of endophytic bacteria and fungi with biological activity. From 8 isolated endophytic ...

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...

The genus Stachys belongs to Lamiaceae family with about 300 species and worldwide distribution. In the present study, the cytotoxic activity of four fractions of different Satchys species (S. byzatina C. Koch., S. inflata Benth., S. setifera Ten. and S. persica Gmel.), has been investigated against HT-29 (colon carcinoma), Caco-2 (colorecta...

BACKGROUND The phytochemical analysis of Stachys alopecuros subsp. divulsa, an endemic Italian species, has been recently reported and has showed the presence of 8-O-acetylharpagide (2), harpagide (3), allobetonicoside (4), and 4¢-O-galactopyranosyl-teuhircoside (5). In this paper, an in deep study of its glycosidic fraction with the aim to widen the knowledge on its secondary metabolites conte...
