Abstract

The invention discloses a garlicin cyclodextrin clathrate compound, preparation and the process for preparing same, wherein the allicin, cyclodextrin or their derivatives (such as beta-cyclodextrin, hydroxypropyl-beta-cyclodextrin) can be used for preparing garlicin cyclodextrin clathrate compound, which can be used for preparing various preparations of different oral preparation, suppositorium, spray, and injection.

Description

technical field [0001] The present invention relates to the field of medical technology, specifically, it uses cyclodextrin or its derivatives to form inclusion complexes with allicin or adds cyclodextrin or its derivatives to improve the solubility and stability of allicin in water and reduce irritation. Sex, mask bad smell, thus make allicin cyclodextrin inclusion compound and its preparation. Background technique [0002] Garlic is the underground bulb of the Allium genus garlic in the Liliaceae family. Spicy in taste, warm in nature, it belongs to the spleen, stomach, and lung meridians, and has the effects of detoxifying, killing insects, reducing swelling, and stopping dysentery. It has been used as a folk medicine in my country for thousands of years. Allicin is the main active ingredient in the volatile oil of garlic. Modern studies believe that allicin has strong antibacterial, antiprotozoal, trichomonas, antiviral, antitumor, antioxidative,...
