Overview | Hypericum perforatum or HypericumperforatumL. Also known as the thousand-storey building, St. John's wort St.John 'sworth, a perennial herb of Hypericum in the family garcinaceae, with multi-glandular spots on its flowers and leaves. It is one of the best-selling herbs in the world in recent years, containing a variety of ingredients with pharmacological effects, its extract is one of the products favored by foreign manufacturers after ginkgo biloba extract. Germany has been used as an antidepressant for over a hundred years. In the '80s, merue bio et al. reported that their active ingredients hypericin and pseudosysin have anti-retroviral Virus including anti-HIV effects against human immunodeficiency Virus. In recent years, foreign anti-AIDS Phase II clinical malignant glioma clinical research is also in progress. |
preparation | will be the raw material of Hypericum perforatum through water soaking means of pretreatment means, the extraction solvent containing effective components such as hypericin and pseudo-hypericin was obtained by alcohol extraction, and the extract rich in effective components was obtained by heating, steaming and concentrating the extraction solvent, can be used for direct drying preparation of extract extract powder, can also be further separated, preparation of high purity hypericin and pseudo hypericin. Specifically, the method for extracting and preparing the dry powder of the extract conforming to the international standard from the raw material of Hypericum perforatum is characterized in that the raw material of Hypericum perforatum is crushed and immersed in water for pretreatment, then, the pretreated raw materials are extracted with alcohol solution to obtain an alcohol solution containing hypericin and pseudo-hypericin, and the extracted alcohol solution is separated, and then the extraction solvent is concentrated and dried, extract extract powder is prepared or used for further refining to prepare high content active ingredient extract. |
biological activity | pseudo Hypericin and its homolog Hypericin are the major phenanthroline compounds in hypericum. Pseudo hypericin has anti-HIV Virus activity. |
