In this research, we investigated the antidiabetic activity of Vitis elegans rhizome, which is used as traditional treatment for diabetes mellitus. The methanol, chloroform, petroleum ether, and hexane extracts of the plant root were obtained through serial exhaustive extraction and were analyzed by Thin Layer Chromatography (TLC).  Glycogen phosphorylase (GP) assay was done to determine the in...

A Vitis hybrid-Vitis coignetiae red wine was vinified by fermentation of a mixture of a Vitis hybrid-Vitis coignetiae must with Saccharomyces cerevisiae KCTC 7904 at 25℃ for 10 days. The Vitis hybrid-Vitis coignetiae red wine showed high antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity (67.8%) and antioxidant activity (76.7%). The antihypertensive ACE inhibitor in the ...

Grape must harbors a complex community of yeast species responsible for spontaneous alcoholic fermentation. Although there are detailed studies on the microbiota of Vitis vinifera L. grapes, less is known about the diversity and behavior of yeast communities present on fermenting grape must from other species of Vitis. In this work, we used a culture-dependent method to study the identity and d...

Vitis hybrid (Sheridan)-Robus coreanus red wine was vinified by fermentation of a mixture of Vitis hybrid and Robus coreanus must at 25℃ for 10 days. The Vitis hybrid-Robus coreanus red wine had ethanol contents of 10.9%. It had high antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity of 57.8% and antioxidant activity of 64.8%. Changes in the physicochemical properties an...

The use of many psychotropic drugs (PDs) is associated with increased caloric intake, significant weight gain, and metabolic disorders. nematode Caenorhabditis elegans (C. elegans) has been used to study the effects PDs on food intake. However, little known about body fat C. elegans. In elegans, feeding behavior metabolism are regulated through independent mechanisms. This aims evaluate intake ...

Trichomes are widely distributed on surfaces of different organs in the grape genus Vitis and are of taxonomic utility. To explore the morphology, structure and ontogeny of Vitis trichomes, we investigated the diversity and distribution of trichomes in 34 species of Vitis. Two main types of trichomes in Vitis are documented: non-glandular and glandular. Within non-glandular trichomes, ribbon an...

Native American grape (Vitis) species have many desirable properties for winegrape breeding, but hybrids of these non-vinifera wild grapes with Vitis vinifera often have undesirable aromas. Other than the foxy-smelling compounds in Vitis labrusca and Vitis rotundifolia , the aromas inherent to American Vitis species are not well characterized. In this paper, the key odorants in wine produc...

salicylic acid (sa) plays a key role in plant disease resistance and hyper-sensitive cell death but is also implicated in hardening responses to abiotic stress. the aim of this study is to examine the effects of salicylic acid on the growth, eco-physiological and biochemical characteristics in zinnia elegans plant exposed to copper stress. effects of copper (cu) on biomass, root length and shoo...
