Extraction, Separation and Purification of Flavones in Onionskin
摘要
Abstract
This paper studied the technological process of extracting flavones from onionskin, established a HPLC method for determining the flavones in the extraction of the onionskin. The optimum ultrasonic extraction conditions for flavones were also established which were soak onion for 20min with 80% ethanol concentration and ratio of liquid to solid was l:10. In the study of the HPLC method for determining the flavones, we got the condition of a 5k~L sample injected, detection was carried out at 360 nm, a mixture of methanol and water with 0. 1% glacial acetic acid (45:55) was used as mobile phase. In the course of separation and purification, we got the crystallization with high pure. By the way of MS and NMR, we knew this material was quercetin.关键词
