Abstract

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

Description

A kind of field thistle is fresh to squeeze vacuum drying powder decoction pieces and its preparation technology

Technical field

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

Background technology

Chinese medicine field thistle is feverfew field thistleCephalanoplos segetum(Bunge) Kitam. dry ground Upper part.This product sweet, bitter, cold, the thoughts of returning home, Liver Channel.This product has cooling blood and hemostasis, the effect of eliminating stasis to resolve swelling, is mainly used in bleeding from five sense organs or subcutaneous tissue, urine Blood, have blood in stool, the treatment of metrostaxis etc..

The processing mode of conventional field thistle medicine materical crude slice is：After harvesting, impurity is removed, is dried, then accumulating of packing.Such herbal medicine drink Piece, bulky, Hygienic Index is poor, easily pollutes and goes mouldy, quality it is difficult to ensure that, be unfavorable for formula adjust and ensure that it faces Bed curative effect, or even to patient bring recessiveness harm.

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

The content of the invention

The invention discloses " a kind of field thistle is fresh to squeeze vacuum drying powder decoction pieces and its preparation technology ".This technique can be most Retain to limits the polarity and nonpolar active ingredient in field thistle medicinal material simultaneously, it is to avoid medicinal material is processed and stored up in existing medicine materical crude slice The loss of active ingredient and the decline of medical material quanlity caused by during fortune, reduce pollution of the medicinal material by mould etc., small to ensuring The steady quality and clinical safety of Ji medicine materical crude slice effectively have great importance.

To achieve these goals, the technical scheme is that：

Its aerial part is gathered in field thistle picking time, is cleaned, after washing, fresh squeezing is taken advantage of.In the dregs of a decoction after squeezing, 1 ~ 5 times is added The water of amount, stirs 5 ~ 30min, juice is taken with plate and frame filter press press filtration.The remaining dregs of a decoction press extracting juice again.Merge three concoctions, with 40 ~ 120 mesh screens, obtain field thistle concoction.Obtained field thistle concoction is concentrated under reduced pressure into relative density under the conditions of 40 ~ 75 DEG C is 1.05 ~ 1.30 medicinal extract, and by its in 40 ~ 70 DEG C vacuum drying 12 ~ 48 hours after crushed 60 ~ 120 mesh sieves, be vacuum-packed, Produce fresh squeeze of field thistle 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.Field thistle is enclosed in bag Thin layer differentiates collection of illustrative plates and/or efficient liquid phase characteristic spectrum, is used as " identity card " of 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 field thistle medicinal material of fresh collection, cleans and is 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 stablized, adjusted beneficial to accumulating and clinic, with very significant social effect And economic implications.

Embodiment

Embodiment 1

By the field thistle medicinal material of fresh collection, clean, silt is washed with water, take advantage of using fresh herb squeezer pressure extracting juice.The gained dregs of a decoction add 3 times The running water of amount, stirs 20min, plate and frame filter press pressure extracting juice.The remaining dregs of a decoction press extracting juice with squeezer again.By above-mentioned 3 Secondary concoction merges, with 100 mesh sieve net filtrations.Filtrate decompression is concentrated, and temperature is set as 65 DEG C.In medicinal extract relative density obtained by concentration For 1.15 when, be transferred in vacuum drying chamber, in 60 DEG C dry 48 hours, after crushing cross 60 mesh sieves, pack, 1kg/ bag, addition Packed antioxidant and drier, Vacuum Package.

Embodiment 2

By the field thistle medicinal material of fresh collection, clean, silt is washed with water, take advantage of using fresh herb squeezer pressure extracting juice.The gained dregs of a decoction add 5 times The running water of amount, stirs 30min, plate and frame filter press pressure extracting juice.The remaining dregs of a decoction press extracting juice with squeezer again.By above-mentioned 3 Secondary concoction merges, with 80 mesh sieve net filtrations.Filtrate decompression is concentrated, and temperature is set as 70 DEG C.In medicinal extract relative density obtained by concentration For 1.10 when, be transferred in vacuum drying chamber, in 65 DEG C dry 12 hours, after crushing cross 60 mesh sieves, pack, 1kg/ bag, addition Packed antioxidant and drier, Vacuum Package.

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