Description
Technical field:
The present invention relates to a kind of processing method of epimedium herb, belong to technical field of Chinese medicine.
Background technology:
Herba Epimedii derives from Berberidaceae Epimedium Epimedium L. plant, be to use one of long Chinese medicine, also be Guizhou genuine medicinal materials and important Miao Ethnomedicine commonly used, successive dynasties book on Chinese herbal medicine and Seedling medical literature are all on the books, and Herba Epimedii has kidney-replenishing, bone and muscle strengthening, effects such as supporing yang beneficial essence cure mainly impotence and seminal emission, and the muscles and bones flaccidity is soft, rheumatic arthralgia, diseases such as numbness contracture.Modern times also are usually used in treating diseases such as osteoporosis, climacteric syndrome, lump in breast, hypertension, coronary heart disease clinically, still have effects such as enhance immunity, defying age, antitumor, anti-AIDS in addition, are subjected to domestic and international extensive concern.
Herba Epimedii is always many with wild kind hyoscine, the Herba Epimedii crude drug of being purchased at present is after the peasant gathers wild epimedium herb mostly, prick conveniently hang on that the hillside tree sticks or the room before dry in the shade naturally behind the house or dry, appearance luster from epimedium herb, the color of blade is black partially, that have even go mouldy, result from the quality of medicinal material detection, during its icariin content and qualified, the time and don't qualified (" 2005 editions regulations of Chinese pharmacopoeia, the Herba Epimedii blade is pressed dry product and is calculated, contain icariin and must not be less than 0.50%), these are to be subjected to the epimedium herb kind, the place of production, collecting time, due to the factor affecting such as processing method, thereby influenced the effective of Herba Epimedii preparation, safety, controlled and stable.
In in recent years to the research that influences Herba Epimedii crude drug qualitative factor, find, even if some kind is according to " the method processed under 2005 editions Herba Epimedii items of Chinese pharmacopoeia, icariin content does not reach the pharmacopeia specified standard yet.The applicant adopts dries in the shade in the pharmacopeia or after the drying in the sun method carries out processed to multiple Herba Epimedii crude drug, measure its icariin content respectively, the result all is lower than 0.50% of pharmacopeia regulation for the icariin content of lower some kinds (as coarse wool Herba Epimedii and Epimedium wushanense etc.) of icariin content own.
Summary of the invention:
The objective of the invention is to: the processing method that a kind of epimedium herb is provided, the present invention is directed to the deficiencies in the prior art, adopt oven drying method that the Herba Epimedii crude drug is carried out processed, in conjunction with the characteristic of producing actual and epimedium active constituent, temperature to oven dry is investigated, reducing the loss of effective ingredient as far as possible, improve the quality and the production and processing efficient of epimedium herb, thereby guarantee with the epimedium herb to be product safe, effective, controlled and stable of raw material.
The present invention is achieved in that the epimedium herb fresh leaves that will gather, weighs, and lay places 140～180 ℃ of baking oven forced air dryings in square plate, stir in good time, and be 3～13 minutes drying time, weighs again, reduces 50 ± 3% to weight and gets final product.
When baking temperature was 140 ℃, be 7～13 minutes drying time.
When baking temperature was 180 ℃, be 3～7 minutes drying time.
For quality and the production and processing efficient that improves epimedium herb, with reference to " under 2005 editions Herba Epimedii items of Chinese pharmacopoeia on the basis of processing method and icariin content assaying method, can reduce the principle that effective ingredient runs off according to quick dewatering drying, in conjunction with the characteristic of producing actual and epimedium active constituent, we have designed the different processing method of epimedium herb, promptly dry in the shade or suning method, oven drying method, (60 ℃ of different temperatures in oven drying method, have been investigated, 100 ℃, 140 ℃, 180 ℃) to the influence of icariin content in the epimedium herb, several epimedium herbs that originate from Guizhou have been carried out experimentation.Through the research more than 2 years, experiment repeatedly, the epimedium herb sample that discovery is gathered behind fixedly epimedium herb kind, the place of production, collecting time, difference because of processing method, the difference of baking temperature particularly, its effective ingredient icariin content widely different increases with the rising of baking temperature.The result is for adopting the epimedium herb blade of 140～180 ℃ of air blast oven drying method processing, its icariin content is than drying in the shade or suning method processing high 2～15 times, the kind icariin content that has reaches 4.20%, surpasses " more than 8 times of 2005 editions regulations of Chinese pharmacopoeia; The kind that has is by drying in the shade or the suning method processed, and its icariin content never reaches Chinese Pharmacopoeia regulation (only being about 0.2%), and after the method processing, icariin content can bring up to 1.50%.
Below be to adopt distinct methods to carry out contrast experiment's research of processed to epimedium herb:
Processing method:
(1) dry in the shade or suning method with the epimedium herb fresh leaves of gathering, weigh, lay dries in square plate or dries in the shade, according to weather condition, the time was generally about a week, weighed again, reduced 50 ± 3% to weight and got final product, and measured its icariin content.
(2) oven drying method is with the epimedium herb fresh leaves of gathering, weigh, lay places 60 ℃, 100 ℃, 140 ℃, 180 ℃ baking oven forced air dryings in square plate respectively, stir in good time, make it to be heated evenly, be respectively 60 ± 10min, 30 ± 10min, 10 ± 3min and 5 ± 2min drying time, weigh again, reduce 50 ± 3% to weight and get final product, measure its icariin content.
Measurement result sees the following form:
The measured content Determination of Icariin of different processing methods is table (n=5, x ± s) as a result
Annotate: "-" expression is not done because of weather or the not enough reason of sample in the table.
By experimental result as seen, adopt the epimedium herb blade of 140～180 ℃ of oven drying method processing, its icariin content obviously improves.
When temperature surpasses 180 ℃, after the Herba Epimedii fresh leaves is put into baking oven, rapid zoom, the epimedium herb appearance color of being processed is bad; When temperature is lower than 140 ℃, some kinds that the icariin content of epimedium herb own is lower, as coarse wool Herba Epimedii and Epimedium wushanense etc., its icariin content does not reach 0.50% of pharmacopeia regulation, and these kinds are main flow kinds of the Herba Epimedii crude drug of purchasing, the coarse wool Herba Epimedii records kind for " Guizhou Province's Chinese crude drug, national quality of medicinal material standard ", and Epimedium wushanense is for " Chinese pharmacopoeia is recorded kind.Therefore, according to the characteristic of producing actual and this composition of icariin, selecting bake out temperature is 140～180 ℃.
Compared with prior art, the epimedium herb blade that adopts the inventive method to process, not only appearance luster and quality are good, difficult going mouldy, the active constituent content height, improved the quality of epimedium herb, guaranteed to be product safe, effective, controlled of raw material and stable with the epimedium herb; And the required place of processing is little, the working (machining) efficiency height, and suitability for scale production has great importance to Herba Epimedii GAP standardized planting, and relevant medical manufacturing enterprise is had stronger practicality.
