Problems solved by technology

[0003] Polygonatum polysaccharides are rich in Polygonatum polysaccharides and other substances, among which polysaccharides of Polygonatum polysaccharides have various functions such as lowering blood sugar, anti-aging, and anti-lipid peroxidation, but at the same time Polygonatum polysaccharides also contain a large amount of fixed calcium oxalate needle crystals, calcium oxalate needles Crystals can directly stimulate mucosal cells and cause cell damage, thereby producing a large amount of inflammatory mediators, causing irritation and even pain. Therefore, during the processing of Polygonatum odoratum, it is necessary to remove calcium oxalate needle crystals in Polygonatum odoratum as much as possible

Abstract

The invention discloses a fresh polygonatum odoratum freeze-dried decoction piece and a preparation method thereof, and relates to the field of traditional Chinese medicine, the fresh polygonatum odoratum is cleaned to remove impurities, the cleaned fresh polygonatum odoratum is cut into thick pieces, the thick pieces are placed in an acidic soak solution containing vegetable oil for ultrasonic impregnation, and the thick pieces are taken out and dried to obtain a first crude product; the first crude product is put into fermentation liquor containing oxalate decarboxylase to be fermented, and a second crude product is obtained after fermentation is finished; the second crude product is subjected to freeze drying under the vacuum condition, and a third crude product is prepared. According to the fresh polygonatum odoratum freeze-dried decoction piece, the content of calcium oxalate in the fresh polygonatum odoratum freeze-dried decoction piece is reduced, and meanwhile the dried decoction piece is not prone to embrittlement and easy to store.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine, in particular to a freeze-dried decoction piece of fresh Polygonatum odoratum and a preparation method thereof. Background technique [0002] The dry rhizome of Polygonatum Polygonatum is long cylindrical, slightly flat, with few branches, 4-18cm long, 0.3-1.6cm in diameter, yellow-white or light yellow-brown surface, translucent, with longitudinal wrinkles and slight The raised link has white dot-shaped fibrous root scars and disc-shaped stem scars, hard and brittle or slightly soft, easy to break, cuticle-like or granular, slightly odorous, sweet, sticky when chewed, and Sweet in taste, slightly cold; returns to lung and stomach meridians; nourishes yin and moistens dryness, produces body fluid and quenches thirst; used for lung and stomach yin injury, dry-heat cough, dry throat and thirst, internal heat and quenching thirst. [0003] Polygonatum polysaccharides are rich in Polygona...
