Abstract

The invention discloses a extractive method of hyperforin phenolic acid and preparation method of hyperforin phenol acid injection. The hyperforin phenolic acid is consisted of total phenolic acid of more than 95 % and total hypericin of 1.2 %. The extraction method of the hyperforin phenolic acid is characterizing by: reflux extracting medicinal materials 3 times with 75 % ethanol, degreasing with ether, extracting with ethyl acetate, eluting D101 resin, which extraction is absorbed on, with ethanol of 40 % and 80 %, concentrating residual liquid and eluent of 40 %, separating by column chromatogram of polyamide, extracting by ethyl acetate, drying, getting phenolic acid extract and mixing with dry matter of 80 % ethanol eluent to prepare hyperforin phenolic acid (intermediate). The injection is prepared of intermediate, medicinal assistant material and water for injection, and can produce to small injection, transfusion agent and freezing-dried powder injection. The injection has high bioavailability, high concentration of blood and medicine, quick effect, and exact curative effect for curing depression, virus A and B hepatitis.

Description

Technical field: [0001] The invention relates to a preparation method of effective part hypericin extracted from Hypericum perforatum medicinal material and an injection thereof, belonging to the technical field of traditional Chinese medicine. The invention has the functions of protecting the liver, soothing the liver and relieving stagnation, and has the effect of antiviral hepatitis, and is mainly used for treating depression caused by emotional discomfort, stagnation of qi, and hepatitis A and B caused by hepatitis virus invasion. viral hepatitis.
