background: coriandrum sativum l. has been recommended for relief of insomnia in iranian traditional medicine. however, no pharmacological studies have yet evaluated its sedative effects. the aim of this study was to determine if extracts and essential oil of coriander seeds have sedative-hypnotic activity.   methods: the aqueous or hydro-alcoholic extracts or essential oil of coriander seeds (...

Aiming at the exploration of herbal use by society, crude extracts of the seeds of some commonly used medicinal plants (Vitis vinifera, Tamarindus indica and Glycin max) were screened for their free radical scavenging properties using ascorbic acid as standard antioxidant. Free radical scavenging activity was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical. The overall antioxi...

The present study is a designed protocol for investigation of the analgesic effect of oral and intraperitoneal (i.p.) administration of alcoholic Datura stramonium (DS) seed extract as a rich source of alkaloid substances. Male NMRI rats were divided into control and treatment groups. The treatment rats received different doses of the DS seed extract, which was prepared from alcoholic smashed s...

Among 60 vining species growing almost exclusively in the Northern hemisphere, only the grapevine (Vitis vinifera L.) (Vitaceae) is the single species largely used in the global wine industry. Grapes are important sources of antioxidants, such as phenolic compounds. The antioxidant activity of these polyphenols is considered much higher than that of the essential vitamins, thus contributing sig...

Polyphenol-rich grape seeds have a beneficial effect on human health. The present study was performed to investigate the effects of grape seeds on antioxidant activities in rats. Male Sprague-Dawley rats were randomly divided into a control diet group (C), a high-fat diet group (HF), a 5% grape seed-supplemented control diet group (G), and a 5% grape seed-supplemented high-fat diet group (HG). ...

The goal of this study was to determine the effect of putrescine, added to the culture medium, on the in vitro development of stenospermic grape (Vitis vinifera L) embryos. The cross breedings of Perlón x G.C88552 and Perlón x Argentina were used. 0 (control), 2 and 4 mM of putrescine were added to the immature seed's culture medium. In Perlón x Argentina, 2 mM of putrescine statistically incre...

Grape seeds represent a high percentage (20% to 26%) of the grape marc obtained as a byproduct from white winemaking and keep a vast proportion of grape polyphenols. In this study, seeds obtained from 11 monovarietal white grape marcs cultivated in Northwestern Spain have been analyzed in order to characterize their polyphenolic content and antioxidant activity. Seeds of native (Albariño, Caiño...

The identification of archaeological charred grape seeds is a difficult task due to the alteration of the morphological seeds shape. In archaeobotanical studies, for the correct discrimination between Vitis vinifera subsp. sylvestris and Vitis vinifera subsp. vinifera grape seeds it is very important to understand the history and origin of the domesticated grapevine. In this work, different car...
