Processing method for simultaneously improving resource utilization rate and quality of herba epimedii medicinal material

Abstract

The invention provides a processing method for simultaneously improving the resource utilization rate and quality of a herba epimedii medicinal material. The method comprises the following steps: removing impurities and residual stems from harvested fresh herba epimedii leaves, flatly laying the herba epimedii leaves in an electric-heating constant-temperature blast drying oven, drying the herba epimedii leaves at 120-135 DEG C for 30-50 minutes, taking out the herba epimedii leaves, and cooling the herba epimedii leaves. Compared with the prior art and a traditional drying method, the drying processing method provided by the invention has the advantages that the quality of the herba epimedii medicinal material can be remarkably improved, the contents of main components, namely icariin and baohuoside I in herba epimedii are greatly increased and reach the standard of the 2015 edition of Chinese pharmacopoeia, and meanwhile, the contents of other main active components are hardly reduced; moreover, the current situation that the quality of commercially available herba epimedii is generally unqualified can be improved, so abandoned medicinal materials which cannot meet the pharmacopoeia standard can be reused, the utilization rate of the resource of the herba epimedii medicinal material is greatly increased, waste of the resource of the herba epimedii medicinal material is avoided, and considerable economic benefits can be brought to the traditional Chinese medicinal material industry.

Description

technical field [0001] The invention belongs to the field of processing traditional Chinese medicinal materials, in particular to a method for drying and processing epimedium medicinal materials. Background technique [0002] Epimedii Folium is a plant of the genus Epimedium in the family Berberidaceae. It is Epimedium brevicomu Maxim., Epimedium sagittatum (Sieb. et Zucc.) Maxim., The dried leaves of Epimedium pubescens Maxim. or Epimedium koreanumNakai have the functions of invigorating kidney yang, strengthening muscles and bones, and dispelling rheumatism. Modern studies have shown that the active ingredients in Epimedium are prenyl flavonoids, such as icariin, epimedin A, epimedin B, epimedin C, and baohuoside I. The 2015 edition of "Chinese Pharmacopoeia" uses the content of icariin as the quality control standard of Epimedium medicinal materials, and stipulates that it should not be less than 0.5%. In 2014, we determined the content of icariin and other index compon...

Problems solved by technology

The 2015 edition of "Chinese Pharmacopoeia" uses the content of icariin as the quality control standard of Epimedium medicinal materials, and stipulates that it should not be less than 0.5%.

Because of this, the results of this study are not simply raising the drying temperature and repeating the previous processing methods, but innovative research based on high-level quality analysis and control methods. The results of the innovative research prove that the patented Epimedium Drying at 140-180°C in "Processing Method of Herba Herba Herba" (ZL 200610200024.7) can indeed increase the content of icariin, but it will lead to the destruction and degradation of other active ingredients in Epimedium and the degradation of the quality of the drug, which is almost not worth the loss
