Abstract

The present invention discloses a method for including andrographolide by using cyclodextrin and its medicinal preparation. The andrographolide is an importent active extract of medicinal plant andrographis. Its inclusion method includes: adding 10-60g of cyclodextrin or its derivative into distilled water and dissolving it; adding 6g of andrographolide extract into 5-10 ml of medicinal methyl alcohol, heating and dissolving it; pouring the cyclodextrin aqueous solution into andrographolide ethyl alcohol solution; ultrasonic vibrating mixed solution in ultrasonic generator for 20-30 min., adopting thin-layer chromatography to identify the cyclodextrin-andrographolide inclusion quality. It does not change chemical property and effective activity of the andrographolide, can be prepared intovarious dosage forms.

Description

Technical field: [0001] The invention relates to an inclusion technology of andrographolide, specifically discloses a method and a medicinal preparation for inclusion of andrographolide with cyclodextrin, and belongs to the technical field of natural medicines. Background technique: [0002] Andrographis paniculata is a plant of the Acanthaceae family, which has heat-clearing and detoxifying properties, and is mainly used to treat diarrhea and dysentery, cold and fever, sore throat, aphtha of the mouth and tongue, and carbuncle sores. Andrographolide is an important extract and active ingredient of the medicinal plant Andrographis paniculata. Its chemical structural formula is: diterpene bicyclic core and its five-membered lactone ring structure are the basic skeleton for clearing away heat and detoxifying. Because the andrographolide compound is insoluble in water, all adopt the way of chemical structure modification to introduce hydrophilic group to prepare various androgr...
