Problems solved by technology

After testing, the extract concentrated by this conventional concentration method has a harpagoside content of 0.18-0.25 mg / g and a glycyrrhizic acid content of 3.87-6.45 mg / g. The granule harpagoside produced by this extract The content is 0.28-0.40mg / 10g granules, and the content of glycyrrhizinic acid is 6-10 mg / 10g granules. It is found through research that in the process of conventional decompression concentration, the temperature of the concentrate is as high as 75-85°C, and harpagoside is at this temperature It is easily oxidized and hydrolyzed to produce cinnamic acid or other components, and glycyrrhizic acid will be partially converted into other components, so the content of active ingredients harpagoside and glycyrrhizic acid in extracts and granules produced by this method are relatively high. Low, correspondingly, leading to a reduction in the content of active substances in the finished drug, which correspondingly reduces the therapeutic effect of the drug

Abstract

The invention provides a preparation method of Xuanmai Ganjie granules. The method comprises the following steps: decocting and concentrating radix scrophulariae, radix ophiopogonis, liquorice and platycodon grandiflorus; and performing refluxing treatment on the concentrate for 2.5-3.5 hours while keeping the refluxing temperature at 55-65 DEG C to finally obtain granules. In the finished product of Xuanmai Ganjie granules prepared in the invention, the contents of active ingredients, namely harpagoside and glycyrrhizic acid, are remarkably increased, and the treatment effect of the medicine is correspondingly enhanced, which is a great beneficial technical progress; and on the premise of neither increasing production equipment nor changing production flow, low cost and high yield are realized, and tremendous economic and social benefits are created by the most economical way.
