BACKGROUND For many years chemical preservatives have been used in food, to act as either antimicrobials or antioxidants or both. In general, consumers regard additive-free foods as safer since preservatives can cause health hazards like asthma and cancer and are suspected to be mutagenic and neurotoxic. The present study was carried out to evaluate the antimicrobial and antioxidant activity of...

A recent article by Rahzani et al. (1) published in the esteemed Cell Journal reported the antioxidative stress activity of Stachys lavandulifolia aqueous extract in humans and suggested its consumption as a supplement in the management of diseases related to oxidative stress. We would like to emphasize some of the limitations regarding antioxidant supplementation, in general, and Stachys lavan...

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 occurrence of diterpenoids from roots and aerial parts of the species of the genus Stachys (Lamiaceae, Labiatae) is reviewed. The presence of these diterpenoids in other taxa and their biological properties have been also reviewed.

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.
