Abstract
The invention discloses dried figwort and a preparation method thereof. The method comprises the steps of figwort digging, cleaning, airing, slicing, microwave vacuum drying, forced air drying and packaging; different drying processes are adopted according to different types of Nanchuan figwort. A microwave vacuum drying technology is applied to the preparation of dried Nanchuan figwort, so that the prepared dried figwort has the advantages of high quality, high efficiency, low consumption and low emission, and the process parameters can be directly used in large-scale production. In the prepared dried figwort, major medicinal compositions of figwort are kept, so that the defects of the conventional medicinal material processing are overcome, and the market benefit can be achieved directly. Moreover, the dried figwort can be taken as high-quality figwort decoction pieces, and is a high-quality medicinal material for development of figwort health-care products.
Description
Technical field
The present invention relates to Chinese medicine manufacture field, in particular a kind of Radix Scrophulariae is done and preparation method thereof.
Background technology
Radix Scrophulariae is the dry root of goatweed Radix Scrophulariae, and another name Radix Scrophulariae, black ginseng, Zhejiang Radix Scrophulariae, black Radix Scrophulariae etc., rank 40 kinds of conventional bulk medicinal materials kinds of China, has the effect of heat-clearing and toxic substances removing, removing heat from blood YIN nourishing.Nanchuan District, Chongqing City, from introducing a fine variety, plant existing more than 50 years history of Radix Scrophulariae, is awarded " township of Chinese genuine medicinal materials Radix Scrophulariae " for 2010,2011 Nian Bei China Chinese crude drug association called afters " Nanchuan Radix Scrophulariae ".Nanchuan Radix Scrophulariae output accounts for the whole nation more than 68% at present, and Nanchuan Radix Scrophulariae main breed is ' river Radix Scrophulariae ', ' grace Radix Scrophulariae ' and ' Zhejiang Radix Scrophulariae ', the dry traditional method of continuing to use to fresh medicine.Because traditional method lacks scientific management and standardized production, directly cause Nanchuan Radix Scrophulariae economic flow rate and commodity price is irregular differs, its quality of remote-effects and popularity.
Radix Scrophulariae main pharmacodynamics composition is iridoid glycoside and Phenylpropanoid Glycosides glycosides, and Harpagide, harpagoside, aucubin are three main iridoid glycoside constituents in Radix Scrophulariae, have the effects such as antiinflammatory, blood sugar lowering, enhancing immunity, anti-hepatitis virus; Angole glycoside C and verbascoside are Phenylpropanoid Glycosides methods of glycosides main in Radix Scrophulariae, have anticoagulant, protect the liver, the effect such as antioxidation.Harpagoside, aucubin poor heat stability, easily decompose, and angole glycoside C and verbascoside absolute acid stability are good, but oxidizable degeneration, so the drying means of fresh medicine and concocting method are larger to its quality influence.
Microwave vacuum drying is Modern New Technology, and it combines microwave drying and vacuum drying advantage separately, extensive use in agricultural product.Modern dry technology is applied to processing of crude drugs, significant for improving quality of medicinal material, enhance productivity and implementing industrialization.
The technology of existing dry Radix Scrophulariae has following shortcoming: (1) is long drying time; (2) baking temperature is high; (3) technique linear dependence is poor; (4) drying process does not relate to the comparison of Radix Scrophulariae breed difference.
Summary of the invention
Technical problem to be solved by this invention is the deficiency existing for prior art, provides a kind of Radix Scrophulariae to do and preparation method thereof.
Technical scheme of the present invention is as follows:
The preparation method that Radix Scrophulariae is dry, its step comprises that Radix Scrophulariae is excavated, cleans, dried, section, microwave vacuum drying, forced air drying, packing.According to Nanchuan Radix Scrophulariae different cultivars, drying process is different; Its drying process is: (1) river Radix Scrophulariae: the first stage adopts 2000W microwave, and dry terminal is discharge rate 55%～57%, meets linear equation y=32.475x-95.313, R2=0.9981; Second stage adopts 1500W microwave, and dry terminal is discharge rate 65%～67%, meets linear equation y=26.323x-18.538, R2=0.9962; Phase III adopts 1000W microwave, and dry terminal is discharge rate 70%～71%; After microwave vacuum drying, forced air drying is to constant weight, and accumulative total discharge rate is 76～77%; (2) grace Radix Scrophulariae: adopt 1500W microwave, dry terminal is discharge rate 60%～62%, meets linear equation y=25.570x-208.92, R2=0.9995; After microwave vacuum drying, forced air drying is to constant weight, and accumulative total discharge rate is 76～78%; (3) Zhejiang Radix Scrophulariae: the first stage adopts 2000W microwave, and dry terminal is discharge rate 44%～46%, meets linear equation y=31.596x-34.275, R2=0.9997; Second stage adopts 1500W microwave, and dry terminal is discharge rate 60%～61%, meets linear equation y=26.716x-68.409, R2=0.9914; After microwave vacuum drying, forced air drying is to constant weight, and accumulative total discharge rate is 75～76%; Wherein, y is displacement, the g of unit; X is the time, the min of unit.
It is dry that described preparation method obtains Radix Scrophulariae.
The present invention is by microwave vacuum drying technology for the dry making of Nanchuan Radix Scrophulariae, and the Radix Scrophulariae that makes is dry has advantages of " high-quality and efficient low consumption low emission ", and its technological parameter can be directly used in large-scale production.The dry main pharmacodynamics composition that has kept Radix Scrophulariae of Radix Scrophulariae prepared by the present invention, has overcome the shortcoming that traditional medicine is processed, and can directly bring market income.In addition, the dry high-quality Radix Scrophulariae decoction pieces that can be used as of this Radix Scrophulariae, is also the high-quality medical material of exploitation Radix Scrophulariae health product.
