Problems solved by technology

[0005] In recent years, the use of microwave-assisted extraction has achieved good results in the extraction of other plant anthocyanins and polyphenols. It has the advantages of accelerating plant cell wall breaking, improving reaction rate and extraction rate, saving solvents, safety, and pollution-free. The extraction method can quickly heat up through microwaves, destroying the cells so that the extract can quickly and efficiently enter the extractant, but the anthocyanin is unstable in nature, and if the extraction temperature is too high, it is easy to oxidize and decompose. Efficient extraction methods of anthocyanins and polyphenols are necessary

Description

technical field [0001] The invention relates to the field of plant extraction, in particular to a method for extracting anthocyanins and polyphenols from calendula. Background technique [0002] Calendula is a plant of the Compositae family, also known as calendula, calendula, and mountain calendula. It is native to southern Europe and the Mediterranean coast. Now it is cultivated in Sichuan, Guizhou, Guangdong, Guangxi and other provinces in my country. It is a kind of A promising economic plant, which can be used in food, medicine and cosmetics, as well as in the chemical industry. Calendula is a variety of volatile oils, total saponins, polyphenols, anthocyanins, pigments, flavonoids, etc. The active ingredient is a functional substance, which has the effects of invigorating the stomach, astringent, hemostasis and healing, and has the effects of moisturizing, anti-inflammation and promoting cell regeneration on the skin. At present, its research is mainly on the volatile oi...
