Problems solved by technology

The traditional sun-drying and drying processing methods cannot strictly control the temperature, which causes the decomposition and loss of active ingredients in Panax notoginseng
Although the more advanced microwave drying, spray drying and infrared drying processes can reduce the impact of improper temperature control on the active ingredients in Sanqi, it is difficult to retain the original color, smell and shape of Sanqi, and the cost of these three drying processes is relatively high
[0004] Since Panax notoginseng has important medicinal value and economic value, and the traditional drying process of Panax notoginseng can no longer meet the current demand, it is urgent to develop a drying process of Panax notoginseng that does not affect the active ingredients and appearance of Panax notoginseng and is easy to operate

Abstract

The invention provides a pseudo-ginseng drying process and a pseudo-ginseng powder preparation process, as well as lyophilized pseudo-ginseng and pseudo-ginseng powder prepared by the same. The pseudo-ginseng drying process comprises the following steps: lyophilizing fresh pseudo-ginseng to obtain lyophilized pseudo-ginseng; drying in three stages, namely drying at the first stage at a heating temperature of 5-20 DEG C and a vacuum degree of 25-35Pa for 10-20 hours, drying at the second stage at heating temperature of 20-40 DEG C and a vacuum degree of 15-25Pa for 3-12 hours, and drying at thethird stage at heating temperature of 40-60 DEG C and a vacuum degree of 2-15Pa for 15-25 hours. The pseudo-ginseng drying process can be used for reducing loss of effective ingredients and keeping the color, smell and shape of pseudo-ginseng. The pseudo-ginseng preparation process adopts a superfine grinding method, is simple in process operation, and the prepared pseudo-ginseng has high contentof effective ingredients and uniform granularity.

Description

technical field [0001] The invention relates to the technical field of preparation of traditional Chinese medicines, in particular to a drying process of notoginseng and a preparation process of notoginseng powder and the obtained freeze-dried notoginseng and notoginseng powder. Background technique [0002] Panax notoginseng is the root tuber of Panax notoginseng of the Araliaceae genus Panax, also known as Jinbuhuan, Tianqi, Tianqi, Shensanqi, and Yunnan Sanqi. It is mainly produced in Yunnan, Guangxi, Sichuan and other places, and it is mostly cultivated. Notoginseng contains 24 kinds of saponins, 17 kinds of amino acids, 17 kinds of trace elements, notoginseng, notoginseng saponins and essential VB, VE and other physiologically active substances. Notoginseng tastes sweet, slightly bitter, warm in nature, and belongs to the liver, stomach, heart, and small intestine meridian. It has the functions of stopping bleeding, dispelling blood stasis, reducing swelling and relievi...
