Abstract

Powder decoction pieces and its preparation technology are dried in vacuo the invention discloses a kind of fresh squeeze of motherwort.The technique is cleaned, eluted, and take advantage of fresh squeezing, leaching concoction after the harvesting of motherwort 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.Motherwort powder decoction pieces prepared by this method, remain 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 motherwort 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 motherwort medicine materical crude slice.

Background technology

Chinese medicine motherwort is labiate motherwortLeonurus japonicusHoutt. on fresh or dry ground Part.This product is pungent bitter, cool, has effects that to invigorate blood circulation, silt of dispelling, menstruation regulating, disappear water, can be clinically used for treating menoxenia, Threatened abortion is had difficult labour, placenta retension, postpartum anemic fainting, abdominal pain due to blood stasis, and metrorrhagia and metrostaxis, rushes down blood, carbuncle swells sore etc. at hematuria.

The processing mode of conventional motherwort medicine materical crude slice is：Tap, dry when summer cauline leaf is luxuriant, Hua Weikai or first is opened, or Segment is dried, packing storage and transport.The motherwort medicinal material that these are dried is bulky, is easy to be contaminated in storage and transport process With go mouldy, quality it is difficult to ensure that, be unfavorable for conditioning agent formulation and ensuring its clinical efficacy.

At present, in the market also has the granule pieces sale that motherwort medicinal material is made after extraction.Due to granule pieces system During standby, not only time consumption and energy consumption is extracted, and is difficult to be extracted because conventional water does the nonpolar active ingredient in solvent, medicinal material Out.Further, since the motherwort medicinal material of extraction is also to dry and by storage for a long time, therefore, the damage of active ingredient Mistake is also very big.In order to ensure the clinic of motherwort medicinal material is effective, steady quality, a kind of new motherwort medicine materical crude slice and its system Standby technique is urgently developed.

The content of the invention

The invention discloses " a kind of motherwort is fresh to squeeze vacuum drying powder decoction pieces and its preparation technology ".This technique can be with Retain the polarity and nonpolar active ingredient in motherwort medicinal material to greatest extent, 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., to ensuring benefit The steady quality and clinical safety of Brittle Falsepimpernel Herb medicine materical crude slice effectively have great importance.

To achieve these goals, the technical scheme is that：

Its aerial part is gathered in motherwort picking time, is cleaned, after washing, the section of 1 ~ 10cm length is cut into, fresh pressure extracting juice, medicine is taken advantage of Slag adds the water of 1 ~ 5 times of amount, stirs 5 ~ 30min, and plate and frame filter press press filtration takes juice, and the dregs of a decoction press extracting juice again, merge 3 concoctions, Juice is filtered to take with 60 ~ 120 eye mesh screens.By the concoction of gained, it is concentrated under reduced pressure in 40 ~ 75 DEG C, it is 1.05 ~ 1.25 to obtain relative density Medicinal extract, temperature be 40 ~ 70 DEG C, pressure be 0.06 ~ 0.09MPa, vacuum drying 6 ~ 24 hours after, crushed 60 ~ 100 mesh sieves, Vacuum packaging, produces fresh squeeze of motherwort and is dried in vacuo powder decoction pieces.

It is the name of an article in printing, medicinal part, planting site, manufacturer, the date of manufacture, main on the label of product packaging bags The information such as component content, meridian distribution of property and flavor, major function, usage and dosage, toxic side effect and contraindication.The thin of motherwort is enclosed in bag 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, being printed on Quick Response Code, former plant photo, medicinal material photo, medicine materical crude slice photo, character and the microscopical characters for obtaining product can be linked by scanning The information such as feature.

The present invention is advantageous in that：

Fresh motherwort medicinal material cleans direct segment after washing and squeezes, filters, being concentrated under reduced pressure, being dried in vacuo resulting powder drink Piece, the active ingredient in medicinal material can be retained to greatest extent.This medicine materical crude slice volume greatly subtracts compared to traditional medicine materical crude slice volume Small, quality is more stablized, beneficial to accumulating and clinical adjustment, with very significant social effect and economic implications.

Embodiment

Embodiment 1

By the motherwort medicinal material of fresh collection, clean, with water wash, be cut into the section of 2cm length, take advantage of using fresh herb squeezer pressure extracting juice. The gained dregs of a decoction add the running water of 2 times of amounts, stir 20min, stand Aspirate supernatant after 30min and filter to obtain concoction.The dregs of a decoction are squeezed Machine is squeezed, leaching concoction.The motherwort concoction that above-mentioned 3 times are filtrated to get merges, and is concentrated under reduced pressure, temperature is set as 60 DEG C. When concentration gained medicinal extract relative density is 1.15, it is transferred in vacuum drying chamber, temperature is 60 DEG C, pressure is 0.09Mpa conditions Under, dry 12 hours, 60 mesh sieves are crossed after crushing, pack adds bagged dryer and antioxidant, Vacuum Package, moisture Not higher than 12%.

Embodiment 2

By the motherwort medicinal material of fresh collection, clean, with water wash, be cut into the section of 5cm length, take advantage of using fresh herb squeezer pressure extracting juice. The gained dregs of a decoction add the running water of 5 times of amounts, stir 30min, stand after 60min, plate and frame filter press press filtration takes juice.Dregs of a decoction squeezer Squeezing, leaching concoction.The motherwort concoction that above-mentioned 3 times are filtrated to get merges, 100 mesh screens, filtrate decompression concentration, temperature It is set as 70 DEG C.When medicinal extract relative density obtained by concentration is 1.10, it is transferred in vacuum drying chamber, temperature is 70 DEG C, pressure Under the conditions of 0.08Mpa, dry 24 hours, 80 mesh sieves are crossed after crushing, pack adds bagged dryer and antioxidant, vacuum Encapsulation, moisture is not higher than 12%.

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.
