Preparation method of rhizoma pinelliae preparata

Abstract

The invention relates to a preparation method of rhizoma pinelliae preparata, in particular to a preparing method of rhizoma pinelliae preparata, comprising the following steps of: preparing clean rhizoma pinelliae, separating according to the size, soaking in clear water till no dried cores are found, and taking out; preparing an appropriate amount of liquorice, adding water and decocting twice, merging the decocted liquor, adding calcined lime blocks in the obtained liquorice juice, adding an appropriate amount of clear water, fusing and removing lime mud, adding soaked rhizoma pinelliae, soaking and stirring once or twice everyday, keeping the pH value of the soaked liquor above 12, taking out till the section is yellow evenly and the mouthfeel is slightly numb, and drying to obtain the finished product, wherein 15kg of liquorice and 10g of calcined lime are used relative to every 100kg of clean rhizoma pinelliae. The method shortens the production time, improves the production efficiency, fully preserves the effective ingredients of the rhizoma pinelliae, greatly reduces the toxic ingredients, ensures the product quality, reduces the accessory consumption, saves the production cost, has easily controlled production process and guarantees the normalization of the rhizoma pinelliae preparation process.

Description

【Technical field】 [0001] The invention relates to a processing method of Chinese medicinal materials, more specifically, to a processing method of Pinellia fragrans. 【Background technique】 [0002] Chinese medicinal materials must be processed into decoction pieces before they can be used as medicine. This is a characteristic of clinical medicine in traditional Chinese medicine, and it is also a unique and proprietary pharmaceutical technology of traditional Chinese medicine. Its long-standing, extensive and profound processing technology and processing culture have risen to the core of the country. Technology and independent intellectual property rights have become a distinctive sign that distinguishes traditional Chinese medicine from Western medicine. At present, the country is also committed to the protection, inheritance, promotion and development of this national traditional technology.

Problems solved by technology

[0006] However, Pinellia is mostly soaked and bleached for a long time during the processing process, and the toxic components of Pinellia are insoluble or difficult to dissolve in water. Short-term soaking cannot achieve the purpose of detoxification, and long-term soaking will lose 88.1% of the water-soluble components. Alcohol-soluble components lose 87.5%, chloroform and methanol eluted components lose 76.6%, alkaloids lose 50%, and their efficacy is significantly reduced. Therefore, shortening the soaking time in water to avoid loss of active components is a technical problem that needs to be solved urgently in the Chinese medicine industry.
