Abstract
In this paper, the carotenoids extraction conditions were studied. We can use petroleum ether and acetone(1:3,v)as extract solvent, and select the solid-liquid ratio of 90 (g/mL). Then we extract lycii carotenoids three times spending 1.5h under this condition. We select hexane acetone(90:10,v)as eluent, magnesium oxide diatomite(1:2,w/w)as adsorbent. Besides, we select petroleum ether and acetone as the developing solvent of TLC. Under this condition, the separation effect for pigment of Fructus Lycii extract and total carotenoid sample is superior.关键词
