Systemic preparation method of chrysanthemum rice essential oil, chrysanthemum rice polysaccharide, chrysanthemum total flavone extract and chrysanthemum rice powder

Abstract

The invention discloses a coproduction method for extracting chrysanthemum rice essential oil from chrysanthemum rice by one-step batch feeding, obtaining chrysanthemum rice polysaccharide from residues after extracting the essence oil, obtaining chrysanthemum total flavones from the residues after obtaining the chrysanthemum rice polysaccharide, and processing the rest residues into chrysanthemum rice powder. By the method, the chrysanthemum rice essential oil can be produced from the same batch of raw materials; oil extraction ratio is up to 5 to 9 percent; the integrated fragrance outline of the chrysanthemum rice essential oil is maintained; the yield of the polysaccharide is over 10 percent; the total flavone content is 20 to 60 percent; the carotene content of the chrysanthemum rice powder is 4 mg/100g; the amino acid content of the chrysanthemum rice powder is about 15 g/100g; the chrysanthemum rice resource is utilized completely; the extracted biological active products can provide raw materials for medicaments, cosmetics and health-care food; and low-cost and high-additional-value production of the chrysanthemum rice is realized.

Description

Systematic preparation method of chrysanthemum essential oil, chrysanthemum polysaccharide, total chrysanthemum flavonoids extract and chrysanthemum powder technical field The invention belongs to the field of extraction, separation and preparation of natural products, and in particular relates to a method for jointly preparing chrysanthemum essential oil, chrysanthemum polysaccharide and chrysanthemum flavonoid extract and chrysanthemum powder by using chrysanthemum flower buds as raw materials. technical background "Zengguang Compendium of Materia Medica" records: "Chrysanthemum, a kind of wild chrysanthemum from Chuzhou Mountain. Scholars pick its pistil (bud) and dry it. It is as big as half a mung bean, very fragrant and light, round and yellow. Poison, powder therapy, expelling wind, clearing fire, and improving eyesight are the first, and produce Suichang stone practice." Zhao Xuemin, a pharmacist in the Qing Dynasty, pointed out that chrysanthemum is the flower bud ...

Problems solved by technology

All existing domestic and foreign about the relevant methods of chrysanthemum extract (CN200510032608.3; 200610049807.X; 200610028335.X;: 2008100609226; 101396387A), but the above reports mainly focus on the sporadic aspects such as flavonoids and essential oil extraction technology of chrysanthemum Technology and simple processing of individual products, lack of related systems, have not formed a large-scale comprehensive utilization of processing technology, resulting in waste of resources and low production efficiency

Jumi polysaccharide contains a very high (15%-30%) content in Jumi, and it has been found in recent studies that it has good antibacterial, anti-inflammatory, and blood lipid-lowering effects, and it has not been passed in previous research reports. The technology integration of the present invention takes full advantage of it
