Description
Invention field
The present invention relates to medicine method for making, particularly a kind of drying means of Radix Scutellariae, belongs to medical technical field.
Background technology
Radix Scutellariae is the dry root of Labiatae herbaceos perennial Radix Scutellariae Scutellaria baicalensis Georgi, and bitter in the mouth is cold in nature, heat clearing and damp drying, eliminating fire and detoxication, removing heat from blood, hemostasis, heat extraction are antiabortive, cure mainly hygropyrexia, fever disease in summer vomiting and nausea uncomfortable in chest, damp and hot feeling of fullness, dysentery, jaundice, cough due to lung-heat, high hot excessive thirst, heat in blood is told nosebleed, carbuncle sore tumefacting virus, the diseases such as frequent fetal movement.
" Chinese Pharmacopoeia " regulation: Radix Scutellariae spring, Qiu Erji excavate, and remove fibrous root and silt, hit rough bark after solarization, dry.Extractum in traditional drying method Radix Scutellariae, content of baicalin are low, quality of medicinal material poor stability.
Summary of the invention
Object of the present invention provides a kind of new Radix Scutellariae drying means, and the Radix Scutellariae extractum of preparation, content of baicalin are high, quality of medicinal material good stability.
The object of the present invention is achieved like this:
A drying means for Radix Scutellariae, is characterized in that: get cadmium yellow a kind of reed mentioned in ancient books, and vexed after steaming, freezing rear dry.
The drying means of a kind of Radix Scutellariae of the present invention, is characterized in that: freezing rear being dried is to be refrigerated to-5 DEG C with down to freezing, dry.
The drying means of a kind of Radix Scutellariae of the present invention, is characterized in that: freezing rear dry be dry or dry or dry after freezing.
So far completed the present invention, radix scutellariae medicinal materials extract content prepared by the present invention is high, and main active content of baicalin is high, and quality of medicinal material is stable.
Further illustrate usefulness of the present invention below by test example, test example is intended to further illustrate usefulness of the present invention, but not restriction of the present invention.
To, with a collection of cadmium yellow a kind of reed mentioned in ancient books, be dried by the following method.
1, dry: remove impurity, dry.
2, after steaming, dry: remove impurity, steam 15 minutes, take out, vexed, dry.
3, steam rear freezing drying: steam 15 minutes, vexed, be refrigerated to-5 DEG C with down to freezing, take out, dry.
One, the dry radix scutellariae medicinal materials extract content comparison of distinct methods
Under Radix Scutellariae item of Chinese Pharmacopoeia version in 2010, Extract mensuration is measured, and the results are shown in Table 1.
Table 1 distinct methods is dried radix scutellariae medicinal materials extract content (%, n=3)
Found out by table 1, after steaming, the content of the freezing Radix Scutellariae extractum drying is the highest.
Two, the dry radix scutellariae medicinal materials content of baicalin comparison of distinct methods
Under Radix Scutellariae item of Chinese Pharmacopoeia version in 2010, determination is measured, and the results are shown in Table 2.
Table 2 distinct methods is dried radix scutellariae medicinal materials content of baicalin (%)
Found out by table 2, the content of freezing rear dry Radix Scutellariae baicalin is the highest.
Three, the dry radix scutellariae medicinal materials quality stability comparison of distinct methods
Experimental condition: each sample is placed 12 months under 25 DEG C ± 2 DEG C of temperature, relative humidity 60 ± 10% conditions, in 0,3,6,9,12 month difference sampling and measuring content of baicalin, be the results are shown in Table 3.
Table 3 distinct methods is dried radix scutellariae medicinal materials quality stability result of the test
Found out by table 3, after steaming, dry and steam that rear freezing to dry baicalin in Scutellaria baicalensis Georgi content high, good stability.
Four, steam the dry radix scutellariae medicinal materials content of baicalin comparison of rear freezing distinct methods
To, with a collection of cadmium yellow a kind of reed mentioned in ancient books, remove impurity, steam 10 minutes, take out, vexed, be divided into 3 parts, to dry respectively, 60 DEG C of oven dry, dry.
Under Radix Scutellariae item of Chinese Pharmacopoeia version in 2010, determination is measured, and the results are shown in Table 4.
The dry content of baicalin (%) of freezing distinct methods after table 4 steams
| Medical material | Dry | 60 DEG C of oven dry | Dry |
| Content of baicalin | 19.14 | 19.11 | 19.13 |
Found out by table 4, freezing drying after steaming, 60 DEG C of oven dry, dry baicalin in Scutellaria baicalensis Georgi content basic identical.
