产品说明

一般描述

Violaxanthin is an epoxidized carotenoid obtained from plants. It is an orange-colored natural xanthophyll pigment.

应用

Violaxanthin has been used as a standard/control in high-pressure liquid chromatography (HPLC) analysis of pigment extracts to confirm the high-level astaxanthin accumulation suspected from the visual phenotype of Nt-AXT plants.

生化/生理作用

紫黄质是一种环氧胡萝卜素,是辣椒素的前体。它是参与绿色植物质体进化(氧进化)的三种叶黄素之一,并参与光诱导的相互转换,即紫黄质循环。9-顺式环氧类胡萝卜素(紫黄质)裂解为黄黄素是脱落酸生物合成的关键调控步骤。
Violaxanthin is a powerful antioxidant and a vital precursor to important compounds like fucoxanthin and β-damascenone. It is a non-photochemical fluorescence quenching structural component of the xanthophyll cycle that shields the photosynthetic system from excessive light. The 2,2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS+) radical scavenging action of violaxanthin extracted from water spinach/water morning glory is strong, and it also inhibits lipid peroxidation and red blood cell hemolysis. Hence, it has the potential to be used in a wide range of medicinal and health products.
