Novel processing method of paeonia sterniana medicinal slices

Abstract

The invention discloses a novel processing method of paeonia sterniana medicinal slices. The method comprises the following steps: (1) impurity removing: sorting the roots of paeonia sterniana and cleaning for later use; (2) pressure-reduced cold soaking and softening: carrying out pressure-reduced cold soaking and softening treatment on the roots of paeonia sterniana; (3) slicing: taking out the roots of paeonia sterniana and cutting into slices with thickness from 1mm to 2mm; (4) drying: drying the slices which are cut well at a temperature of 55 DEG C to 60 DEG C until the content of water in the slices reaches 8% to 12%; (5) packaging: cooling the slices to a room temperature and packaging in a sealing manner. According to the method, the roots of paeonia sterniana are softened via a pressure-reduced cold soaking method, so that the softening efficiency and the softening quality are substantially improved and the production period of the paeonia sterniana medicinal slices is shortened; the softening and soaking processes are both carried out below 30 DEG C, so that the damage to the roots of paeonia sterniana, due to the heating, is avoided, i.e., the loss of paeoniflorin is substantially reduced; any materials are not added during the whole process of the method, so that the medicinal properties of the paeonia sterniana medicinal slices are not changed.

Description

technical field [0001] The invention relates to a new method for processing Radix Paeoniae Alba decoction pieces, belonging to the technical field of Radix Paeoniae Alba medicinal material processing. technical background [0002] Chinese herbal decoction pieces are not only one of the three pillars of the Chinese medicine industry, but also occupy a central position. It can be directly formulated and taken as decoction according to the prescription of traditional Chinese medicine, and can also be used as raw material medicine for the production of Chinese patent medicine. Therefore, its quality directly affects the clinical efficacy of traditional Chinese medicine. [0003] The traditional processing process of Chinese herbal pieces is mainly cleaning, moistening, cutting, and processing. The root of Paeoniae Alba is hard, and it usually needs to be softened before slicing. The traditional softening treatment generally uses moistening. Low temperature often causes the med...

Problems solved by technology

Since the steaming method and cooking need to be heated to a temperature of about 100°C, and the outer skin of the Radix Paeoniae Alba root is removed before the steaming method and cooking, the method will greatly damage the paeoniflorin, and the addition of alum and ginger will change the medicinal properties of the Radix Paeoniae Alba. Does not meet the processing requirements of traditional Chinese medicine
