Abstract

The invention discloses a preparation method of a fresh dendrobium aqueous extract for treating cell injury and inflammation, and relates to the technical field of pharmacy. The invention aims to solve the problem of inflammation curative effect caused by cell injury of dendrobium. The method specifically comprises the following steps: taking 100g of fresh dendrobium, removing roots and leaves, reserving stems, crushing, and sieving with a 100-mesh sieve; adding 400-800ml of distilled water to immerse the medicinal materials, and repeatedly extracting for 2-4 times in a water bath of 70-85 DEG C, 1 hour each time; collecting multiple filtrates, combining, and filtering and sterilizing by using a filter membrane to obtain an extracting solution; concentrating a fresh dendrobium extracting solution at 40-55 DEG C under reduced pressure until the volume is 1 / 6-1 / 8 of the original volume, and then freeze-drying until the weight is constant. The fresh dendrobium is dendrobium huoshanense, dendrobium officinale, dendrobium nobile, dendrobium fimbriatum, dendrobium chrysotoxum, dendrobium aphyllum and dendrobium primulina. The fresh dendrobium aqueous extract has a certain protection effect on treatment of cell injury, and can inhibit inflammatory response induced by LPS..

Description

technical field [0001] The invention relates to the technical field of pharmacy, in particular to a method for preparing fresh dendrobium water extract for treating cell damage and inflammation. Background technique [0002] Trauma is an important disease that affects the health of the body. All skin trauma involving the dermis will end in the formation of scar tissue. Excessive hyperplasia of scar tissue often destroys the integrity of the human body surface, which not only affects the appearance, but also seriously affects the body. normal function. Fibroblasts are the main effector cells of scar tissue formation. Their activation, proliferation, migration, collagen synthesis and abnormal differentiation directly lead to the formation of scar tissue. At present, there are many kinds of drugs for treating scar formation, but the therapeutic effect is mediocre, and they have toxic and side effects, so their clinical application is restricted. The fresh or dried stems of va...
