Abstract

The invention discloses a method for extracting fructus amomi volatile oil, fructus amomi flavone and fructus amomi polysaccharide by utilizing fructus amomi. The method comprises the following steps: grinding fructus amomi, heating and extracting with a volatile oil extractor; condensing vapor in the extracting process to collect the fructus amomi volatile oil; sequentially centrifuging, concentrating, performing alcohol precipitation and centrifugally separating the fructus amomi extracted raw liquor in the extrator to obtain alcohol-precipitated supernate and alcohol-precipitated precipitation; concentrating the alcohol-precipitated supernate, and performing spray drying to prepare the fructus amomi flavone extract; and drying the alcohol-precipitated precipitation by adopting a heat-circulation oven or a plate-type vacuum dryer to prepare the fructus amomi polysaccharide extract. According to the method, the fructus amomi is extracted once to obtain the fructus amomi volatile oil, fructus amomi flavone and fructus amomi polysaccharide extract simultaneously, and realizes comprehensive utilization. The prepared products can be applied to foods, medicines and other fields, so that the production cost is effectively reduced, and reasonable utilization of resources is realized. The method has remarkable economic and social benefits.

Description

technical field [0001] The invention belongs to a preparation method of a traditional Chinese medicine extract, in particular to a method for extracting amomum volatile oil, amomum flavonoids and amomum polysaccharides by using amomum. Background technique [0002] Amomum villosum is the dry mature fruit of Amomum villosum Lour, Amomum villosum Lour. var. xanthioides T.L.Wu et Senjen or Amomum longiligularg T.L.Wu. The growth conditions of amomum are harsh, and they need to be grown in high temperature, humid subtropical regions, damp, warm, hot and foggy areas with annual rainfall above 1000mm, such as Yangchun and Gaozhou in Guangdong, and earthquakeproof areas in Guangxi. The yield per mu is about 110 kg, and the annual Amomum production is less. Amomum has the functions of dispelling dampness and appetizing, warming the spleen and stopping diarrhea, regulating qi and preventing miscarriage. It is mainly used for symptoms such as dampness and turbidity in the middle, abd...
