An HPLC-DAD method has been developed to quantitatively analyze for the content of zeaxanthin dipalmitate, a major carotenoid in Fructus Lycii, in different species of the genus Lycium. Determination was performed using an Alltima C18 column with the mobile phase consisting of acetonitrile and
Zeaxanthin dipalmitate (ZDP) is a major non-saponified carotenoid in fully ripe fruits of Lycium barbarum L. In the present study, response surface methodology was used to optimize the ultrasonic-assisted extraction (UAE) conditions of carotenoids from the fruits of L. barbarum, and the optimal
An efficient combination strategy based on high-speed shear dispersing emulsifier technique and high-performance counter-current chromatography was developed for on-line extraction and isolation of carotenoids from the fruits of Lycium barbarum. In this work, the high-speed shear dispersing
