Embodiment 1

[0019] A kind of extracting method of Tian Qi oil, the step of its extracting method is:

[0020] (1) Pre-extraction treatment: Weigh a certain amount of rhizome of Tianqi, put it into the grinder for super grinding, and obtain the grinding material A, and set it aside;

[0021] (2) Initial extraction: add ethyl acetate, just submerge the grinding material A obtained in step (1), select the extraction temperature as 35°C, the extraction pressure as 10MPa, the extraction time as 30min, and the flow rate of carbon dioxide as 10L / h to obtain the extraction Liquid B, spare;

[0022] (3) Alkalinization: Extract the extract B obtained in step (2) with 0.25% sodium hydroxide solution at a concentration of 1 times for 3 consecutive extractions, collect the oily liquid in the upper layer to obtain oily liquid C, and set aside;

[0023] (4) Acidification: Add 2 times the amount of 2mol / L hydrochloric acid dropwise to the oily liquid C obtained in step (3) for acidification until the bl...

Abstract

The invention relates to an extraction method of pseudo-ginseng oil. The extraction method changes a traditional crushing and water-alcohol extraction method, and implements extraction by using superfinishing and supercritical carbon dioxide extraction method; and the extraction method comprises the following steps: (1) pretreatment; (2) primary extraction; (3) alkalization; 4) acidification; and (5) extraction. The extraction method both can improve the extraction rate of pseudo-ginseng oil, and can reduce the production cost, thereby providing raw material guarantee for the development of multiple pseudo-ginseng oil dosage forms.

Description

technical field [0001] The invention belongs to the field of veterinary medicine, in particular to a method for extracting Tianqi oil. Background technique [0002] Tianqi, a perennial herb, is mostly used in the folks in my country to treat bruises and swelling, chest pain, blood stasis, amenorrhea, dysmenorrhea, postpartum stasis of yin and abdominal pain, and sore carbuncle swelling and pain. Studies have shown that it contains a variety of active ingredients, the most important of which is Tianqi oil, which has the functions of antibacterial and hemostatic, regulating cardiovascular and body immune mechanisms, and has been widely used in the fields of medicine, food and chemical industry. Lead compounds of potential development value. [0003] At present, there is no perfect extraction scheme for Tianqi oil, so the main purpose of the present invention is to provide an extraction process for Tianqi oil, improve the oil yield of Tianqi oil, and reduce production costs. ...
