Chinese thorowax root screening and processing method

Abstract

The invention discloses a Chinese thorowax root screening and processing method. The steps of the method include impurity removing, cleaning, softening and drying. Instead of adopting traditional stewing and softening methods, the method adopts the softening method combining enzyme treatment and ultra-low temperature crushing effects, so that softening effects can be more prominent, convenient slicing can be achieved, and processing periods can be effectively shortened; many activity factors are embedded in the fiber structure of Chinese thorowax root, and partial cellulose and hemicellulose can be degraded by cellulase, so that the whole structure can become bulky and porous, and drug effects can be achieved more easily when decoction pieces are finally boiled and more easily to be absorbed; and through the enzymatic treatment of cutinase, the hydrolysis of keratinous polymer of the cuticle of the Chinese thorowax root can be catalyzed, monomers and oligomers can be hydrolyzed, and therefore, the dissolution of effective components in the decoction pieces can be further promoted.

Description

technical field

[0001] The invention relates to the technical field of processing Chinese medicinal materials, in particular to a method for screening and processing Bupleurum bupleuri. Background technique

[0002] Bupleurum, the name of traditional Chinese medicine. It is a herbal medicine included in "Chinese Pharmacopoeia", and the medicinal part is the dried root of Bupleurum bupleuri or Bupleurum angustifolia. Excavated in spring and autumn, removed stems, leaves and sediment, and dried. Bupleurum is commonly used to relieve symptoms. Also known as Dixun, Shancai, Mushroom Grass, and Firewood, it is bitter in nature and slightly cold, and returns to the Liver and Gallbladder Meridians. It has the effects of reconciling the exterior and interior, soothing the liver and promoting yang. For cold and fever, alternating cold and heat, malaria, liver depression and Qi stagnation, sternocostal pain, anal prolapse, uterine prolapse, and irregular menstruation.
