Abstract

The invention relates to a preparation method of superfine powder of rhizome of conic gymnadenia. The preparation method adopts fresh or dry rhizome of conic gymnadenia tubers as main raw materials and mainly comprises the following steps: (1) cleaning the raw materials of the rhizome of conic gymnadenia and removing external impurities; (2) soaking with a baking soda aqueous solution to deodorize; (3) drying at low temperature to obtain a clean dry product; (4) primarily crushing the rhizome of conic gymnadenia to meet the particle diameter in sample injection of superfine crushing equipment;and (5) carrying out superfine crushing at low temperature to obtain a sample. The preparation method has the advantages that the physical technologies are adopted in the whole preparation process, the operation is simple and convenient; due to the physical methods, the pollution of organic reagents to the raw materials is avoided, and the activity of functional substances such as mucilage and protein and the like can be retained to a greatest extent.

Description

technical field [0001] The invention belongs to the pulverization processing of traditional Chinese medicines, and in particular relates to a method for preparing superfine powder of palm ginseng with a particle diameter of ≤2.5 μm. Background technique [0002] Palm ginseng is a plant of the genus Gymnadenia in the family Orchidaceae, with a Latin name of Gymnadenia conopsea (L.) R.Br. It gets its name from its underground rhizome shaped like a palm. Produced in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei, Shanxi, Shaanxi, southeastern Gansu, western to northern Sichuan, northwestern Yunnan, and southeastern Tibet. Growing in hillside forest, grassland or gravel beach grass at an altitude of 265-4700m. [0003] Ginseng palm tuber is mainly composed of mucus, starch, protein, sugar, calcium oxalate and inorganic salts, and is a traditional national medicine. Tibetan medicine and Naxi medicine use tubers as medicine, and are used for lung deficiency asthma, tuberc...
