Title:
INDUSTRIALIZED METHOD FOR RAPIDLY AND EFFICIENTLY EXTRACTING XANTHOPHYLL AND QUERCETAGETIN
Document Type and Number:
WIPO Patent Application WO/2020/228786
Kind Code:
A1
Abstract:
The present invention relates to the field of natural product extraction, and in particular relates to an industrialized method for rapidly and efficiently extracting xanthophyll and quercetagetin. The main improvement of the method lies in that a mixed solution of n-hexane and acetone solution is used as an extracting agent to extract marigold flower particles, wherein the volume fraction of acetone in the acetone solution is 80%-100%. The mixed extracting agent of the present invention has very high selectivity with regard to xanthophyll and quercetagetin, and can be used for effectively extracting the two effective components, and subsequently, xanthophyll and high-purity quercetagetin products can be obtained through simple separation; and the industrialized method has a simple process, is low in production cost, and is conducive to industrialized production.
