Abstract

The invention discloses a kind of " glutinous rehmannia is fresh to carry vacuum drying powder decoction pieces ", are primarily characterized in that：Glutinous rehmannia harvest after, take advantage of it is fresh wash, be sliced, squeezing the juice, extracting, after extracting solution is condensed into clear cream, then be dried under vacuum to water content be less than 10%, crush, be sieved after be vacuum-packed.This prepared slice quality is stablized, and can both enter decoction decocting, can also directly enter pill, powder, tablet, capsule, is conducive to carry, Clinical practice is convenient.

Description

Glutinous rehmannia is fresh to carry vacuum drying powder decoction pieces

Technical field

The invention belongs to prepared slices of Chinese crude drugs technical fields, especially belong to the manufacture field of radix rehmanniae.

Background technology

Chinese medicine glutinous rehmannia is the fresh or dried root of scrophulariaceae rehmannia glutinosa plant.Glutinous rehmannia has clearing heat and cooling blood, nourishing Yin and promoting production of body fluid Effect.This product is mainly used for treatment heat and enters ying blood, febrile virulent maculae, hematemesis and epistaxis, consumption of YIN caused by febrile disease, the deep red polydipsia of tongue, Tianjin hinder constipation, the moon It shoots without hitting the target heat, hectic fever due to yin labor heat, Heat Diabetes etc. is a herb common on tcm clinical practice.The processing method of traditional glutinous rehmannia is：Autumn Season excavates, and removes removing LU, fibrous root and silt, using fresh herb；Or glutinous rehmannia is slowly baked to about most probably dry, packing, storage and transportation.To medicine materical crude slice factory Afterwards, it then washs, soften, be sliced, dry, pack.Such medicine materical crude slice volume is big, and Hygienic Standard is poor, is easy to make moist, is mildew, infested, It is unfavorable for taking care of, storage and transportation cost are high.In addition, such radix rehmanniae quality stability is poor, clinical efficacy is difficult to ensure, Patient takes inconvenience, works slow.Therefore, develop a kind of stable quality is reliable, storage/transportation is at low cost, be conducive to keeping, carry It is imperative with easy to use, rapid-action novel radix rehmanniae.Radix rehmanniae currently on the market, in addition to traditional medicine materical crude slice it Outside, also two kinds of forms of Ultramicro-powder medicine materical crude slice and concentrated granular medicine materical crude slice, but both using traditional medicine materical crude slice as raw material, quality determines In the quality of traditional medicine materical crude slice, and ultramicro decoction piece cannot solve the problems, such as that medicinal material pollutes；Concentrated granular can only extract it is water-soluble at Point.

Invention content

The invention discloses a kind of " glutinous rehmannia is fresh to carry vacuum drying powder decoction pieces ", are primarily characterized in that：It is harvested in glutinous rehmannia Afterwards, it cleans in time, removal impurity and the dis-medicinal part such as silt, cleans in taking advantage of using fresh herb tap water in 24 hours and be cut into 2 ~ 5mm Thick piece.The piece that this cuts is added in the water of 1 ~ 5 times of 50 ~ 70 DEG C of weight, impregnate and is constantly stirred 5 ~ 30 minutes, filtering, medicine Slag presses extracting juice.The water that 5 ~ 10 times of weight is added in the gained dregs of a decoction is boiled 10 ~ 30 minutes, is filtered while hot, the dregs of a decoction squeeze again Juice collects concoction.Merge above-mentioned concoction, crosses 60 ~ 100 mesh sieve, be concentrated under reduced pressure, temperature is 50 ~ 75 DEG C, and being concentrated into relative density is 1.15 ~ 1.25 clear cream.The clear cream of gained is dried under vacuum to water content at 60 ~ 80 DEG C and is less than 10%, is crushed, 60 mesh sieve is crossed, Vacuum packaging is to get finished product.Finished product medicine materical crude slice must not be less than 0.040% containing acteoside.This radix rehmanniae clinic generally uses Amount is 1 ~ 5g, can both enter decoction decoction, take after mixing it with water, and also can directly enter in pill, powder, capsule and tablet, to greatly improve The convenience and compliance of Clinical practice, is conducive to the treatment of clinical acute disease.

The present invention solve traditional radix rehmanniae is bulky, carrying cost is high, be unfavorable for keeping, easily mildew it is infested, defend The shortcomings such as the poor, unstable quality of raw condition, due to being to take advantage of fresh extraction, quality is drunk than ultramicro grinding medicine materical crude slice and concentrated granular Piece is more preferable.

Specific embodiment

It after glutinous rehmannia medicinal material is harvested, cleans, removes impurity and the dis-medicinal parts such as silt, using fresh herb is taken advantage of in 6 hours originally Water is cleaned, and is cut into the piece of 3mm thickness.This piece is added to 70 DEG C of pure water of 5 times of weight, is stirred 30 minutes, filtering, dregs of a decoction pressure Extracting juice.The pure water for adding 8 times of weight into the above-mentioned dregs of a decoction again is boiled 20 minutes and is extracted, filters while hot, the dregs of a decoction are again It squeezes the juice, collects concoction.Merge above-mentioned concoction, be concentrated under reduced pressure, temperature be set as 70 DEG C, be concentrated into relative density be 1.20 it is clear Cream.It is 8% that the clear cream of gained is dried under vacuum to water content at 80 DEG C, is crushed, and crosses 60 mesh sieve, is vacuum-packed to get finished product. The content of acteoside is 0.050% in finished product medicine materical crude slice.

Claims

1. a kind of glutinous rehmannia is fresh to carry vacuum drying powder decoction pieces, it is primarily characterized in that：It after glutinous rehmannia harvests, cleans, removes in time The impurity such as silt and dis-medicinal part are added 1 ~ 5 times in the piece for taking advantage of using fresh herb tap water in 24 hours and cleaning and being cut into 2 ~ 5mm thickness The water that 50 ~ 70 DEG C of weight is impregnated and is constantly stirred 5 ~ 30 minutes, and filtering, dregs pressing takes juice；5 ~ 10 are added in the gained dregs of a decoction The water of times weight, boils 10 ~ 30 minutes, filters while hot, and the dregs of a decoction are squeezed the juice again, collects concoction；Merge above-mentioned concoction, crosses 60 ~ 100 Mesh sieves, and is concentrated under reduced pressure, and temperature is 50 ~ 75 DEG C, is concentrated into the clear cream that relative density is 1.15 ~ 1.25；By the clear cream of gained 60 ~ It is dried under vacuum to water content at 80 DEG C and is less than 10%, crushes, crosses 60 mesh sieve, is vacuum-packed to get finished product；Finished product medicine materical crude slice stamen containing hair Flower glucosides must not be less than 0.040%.
