Abstract

The invention discloses a kind of fresh preparation technology for squeezing vacuum drying powder decoction pieces of black nightshade.The technique is cleaned, eluted after the harvesting of black nightshade medicinal material, and takes advantage of fresh squeezing, leaching concoction.The dregs of a decoction add water stirring, filtering squeezing.Gained concoction is concentrated under reduced pressure after merging, and is dried in vacuo, is vacuum-packed after crushing.Black Nightshade Herb medicine materical crude slice prepared by this method, remains the polarity in medicinal material and nonpolar active ingredient to greatest extent.Medicine materical crude slice is beneficial to accumulating, and convenient to adjust, quality controllable, curative effect is reliable, to ensureing that tcm clinical curative effect has great importance.The promotion and implementation of this law, will there are significant social effect and economic benefit.

Description

A kind of fresh preparation technology for squeezing vacuum drying powder decoction pieces of black nightshade

Technical field

The invention belongs to Chinese medicine manufacture field, more particularly to the processing technology of Chinese medicine black nightshade medicine materical crude slice.

Background technology

Chinese medicine black nightshade is plant of Solanaceae black nightshadeSolanum nigrumL. aerial part.With clearing heat and detoxicating, diuresis Effect.Clinic is mainly used in sore and toxic, skin eczema, difficult urination, chronic senile tracheitis, leukorrhea, prostate The treatment of inflammation, dysentery etc..

The processing mode of conventional black nightshade medicine materical crude slice is：Impurity is removed after harvesting, is dried, directly packing storage and transport.This Dry black nightshade Hygienic Index can not be up to standard a bit, and medicinal material easily occurs and goes mouldy, so as to cause the decline of medical material quanlity and clinic The reduction of curative effect.Such prepared herbal medicine in small pieces ready for decoction, it is bulky, easily occur it is rotten and contaminated, quality it is difficult to ensure that, be unfavorable for adjustment and match somebody with somebody Just and ensure its clinical efficacy.

At present, in the market also has the manufactured granule pieces sale after extraction of black nightshade medicinal material.The preparation of granule pieces Journey, extraction not only time consumption and energy consumption, and do solvent because commonly using substantial amounts of water, the nonpolar active ingredient in medicinal material is difficult to be extracted Out.Further, since the black nightshade medicinal material of extraction is also to dry and by storage for a long time, therefore, the loss of active ingredient It is and very big.In order to ensure the clinic of black nightshade medicinal material is effective, steady quality, a kind of new black nightshade medicine materical crude slice and its preparation technology Urgently develop.

The content of the invention

The invention discloses " a kind of fresh preparation technology for squeezing vacuum drying powder decoction pieces of black nightshade ".This technique can be maximum The polarity and the nonpolar active ingredient that retain in black nightshade medicinal material of limit, avoid medicinal material from being processed and storage and transport process in existing medicine materical crude slice In the loss of caused active ingredient and the decline of medical material quanlity, reduce medicinal material by mould etc. pollution, to ensuring black nightshade medicine materical crude slice Steady quality and clinical safety effectively have great importance.

To achieve these goals, the technical scheme is that：

Its aerial part is gathered in black nightshade picking time, is cleaned, after washing, is cut into 1 ~ 2cm section, adds 0.5 ~ 2 times of amount of medicinal material amount Water, stir 5 ~ 10 minutes, take advantage of fresh squeezing, the dregs of a decoction add the water of 1 ~ 5 times of amount, stir 5 ~ 30min, press extracting juice, merge twice Concoction, 40 ~ 120 mesh screens, obtain black nightshade concoction.Obtained black nightshade concoction is concentrated under reduced pressure into relatively under the conditions of 40 ~ 75 DEG C Density is 1.05 ~ 1.30 medicinal extract, and crushed 60 ~ 120 mesh sieves, vacuum after it is dried in vacuo 48 ~ 72 hours in 40 ~ 70 DEG C Packaging, produce fresh squeeze of black nightshade and be dried in vacuo powder decoction pieces.

On the label of product packaging bags, the name of an article in printing, medicinal part, planting site, medicine materical crude slice manufacturer, the date of manufacture, The information such as Contents of Main Components, meridian distribution of property and flavor, major function, usage and dosage, toxic side effect and contraindication.The included upper black nightshade of bag Thin layer differentiates collection of illustrative plates and/or efficient liquid phase characteristic spectrum, " identity card " as product.In addition, in the packaging bag of product, print There is Quick Response Code, former plant photo, medicinal material photo, medicine materical crude slice photo, character and the micro- mirror for obtaining product can be linked by scanning The information such as other feature.

The present invention is advantageous in that：

The black nightshade medicinal material of fresh collection, clean and directly squeezed after washing, filter, be concentrated under reduced pressure, being dried in vacuo, resulting powder Medicine materical crude slice, the active ingredient in medicinal material can be retained to greatest extent.This medicine materical crude slice volume compared to traditional medicine materical crude slice volume greatly Reduce, vacuum packaging so that prepared slice quality is more stable, is adjusted beneficial to accumulating and clinic, has very significant social effect And economic implications.

Embodiment

Embodiment 1

By the black nightshade medicinal material of fresh collection, clean, silt is washed with water, be cut into 1cm section, add the water of 1 times of amount, stirring 5min, take advantage of using fresh herb squeezer pressure extracting juice.The gained dregs of a decoction add the water of 5 times of amounts, stir 20min, press extracting juice.By above-mentioned 2 times Concoction merges, with 100 mesh sieve net filtrations.Filtrate decompression concentrates, and temperature is set as 65 DEG C.It is in medicinal extract relative density obtained by concentration When 1.10, it is transferred in vacuum drying chamber, is dried 48 hours in 75 DEG C, low-temperature grinding, moisture is not higher than 12%.

Embodiment 2

By the black nightshade medicinal material of fresh collection, clean, silt is washed with water, be cut into 2cm section, add the water of 2 times of amounts, stirring 10min, take advantage of using fresh herb squeezer pressure extracting juice.The gained dregs of a decoction add the water of 10 times of amounts, stir 30min, press extracting juice.By above-mentioned 2 Secondary concoction merges, with 80 mesh sieve net filtrations.Filtrate decompression concentrates, and temperature is set as 70 DEG C.In medicinal extract relative density obtained by concentration For 1.15 when, be transferred in vacuum drying chamber, in 70 DEG C dry 72 hours, low-temperature grinding, moisture be not higher than 12%.

Above example, only illustrate the technological thought of this invention, it is impossible to it is all whereby to limit protection scope of the present invention It is any change for being done on the basis of technical scheme according to technological thought proposed by the present invention, each falls within what the present invention protected Within the scope of.
