Stilbenes Analysis

v-innovate Technologies provides one-stop high performance liquid chromatography (HPLC) services covering a wide variety of plant targeted metabolomics. Our stilbenes analysis services use HPLC technologies to deliver high resolution and reliable identification and quantification of stilbenes.

Overview

Stilbenes are the general name for a class of substances that have a parent nucleus of homo stilbene or its polymers. Monophenol and diphenolic hydroxy astragalus compounds are mainly found in parenchyma cells of the xylem of plant tissues. When the plant is infected by bacteria or stimulated by the outside, the total content of the stilbenes in the stimulated tissue area increases significantly. Therefore, natural stilbenes compounds may be stress products of plants. Stilbenes have a wide range of biological activities. In addition to the known antibacterial effect, some stilbenes have been found to have the effect of lowering blood lipid. Rhaponticin isolated from rhubarb has been applied in the clinical treatment of hyperlipidemia. There are some stilbenes that can protect the liver, dilate capillaries to improve microcirculation, dilate coronary vessels, lower blood pressure, fight allergies, inhibit platelet aggregation and fight tumors. The biological activity of stilbenes has been widely concerned. High performance liquid chromatography (HPLC) is a sensitive analytical technique that enables detection, identification and quantification of a variety of stilbenes by characterizing their chemical structure, even at low abundance. Comprehensive phytohormone profiling helps elucidate a plant’s responses to different conditions such as mutations, stress, and hormone treatments.

Applications of Stilbenes Analysis

• Reveal mechanisms of plant development
• Uncover plant's responses to biotic and abiotic stresses
• Safety assessment of crops
• Crop improvement
