Description

Radix bupleuri processed product and processing method thereof
Technical Field
The invention relates to the technical field of processing of traditional Chinese medicine decoction pieces, in particular to a radix bupleuri processed product and a processing method thereof.
Background
The Chinese medicinal material bupleuri radix is derived from dried root of Bupleurum chinense DC or Bupleurum angustifolium Willd belonging to Umbelliferae, and has been used as traditional Chinese medicine for thousands of years. The research shows that: the bupleuri radix contains saponin, volatile oil, polysaccharide, flavone, etc., and has antiinflammatory, antibacterial, and antiviral effects. Saikosaponin (saikoaponins, SS) is the main chemical and bioactive components of bupleurum, and the chinese pharmacopoeia (first part of 2020 edition) uses the total amount of Saikosaponin a (saikoaponin a, SSa) and Saikosaponin d (saikoaponin d, SSd) as the quality control index of bupleurum medicinal material. Both SSa and SSd belong to the class of native saponins. Clinically, the bupleurum is mainly decocted into a decoction, so that the content of SSa and SSd in the decoction can be influenced, and further the drug effect is influenced.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a radix bupleuri processed product and a processing method thereof, so as to solve the problems of low saikosaponin content and low dissolution rate in the conventional radix bupleuri processed product.
The technical scheme for solving the technical problems is as follows: provides a processing method of a radix bupleuri processed product, which comprises the following steps:
(1) soaking radix bupleuri crude decoction pieces in sodium bicarbonate water solution;
(2) parching the soaked radix bupleuri crude decoction pieces with slow fire, and cooling to obtain radix bupleuri processed product.
The invention has the beneficial effects that: saikosaponin (saikoaponins, SS) is the main chemical and bioactive components of bupleurum, and the chinese pharmacopoeia (first part of 2020 edition) uses the total amount of Saikosaponin a (saikoaponin a, SSa) and Saikosaponin d (saikoaponin d, SSd) as the quality control index of bupleurum medicinal material. SSa and SSd both belong to primary saponins, epoxy ether bonds in the structures of the primary saponins are unstable, and are easy to crack to form secondary saponins, the bupleurum is processed by an alkaline method, and the cracking of the epoxy ether bonds can be inhibited in an alkaline environment, so the content of the saikosaponin in the bupleurum can be improved, and meanwhile, certain combined type saikosaponin can be directly or indirectly converted into free type saikosaponin in the roasting processing process, so the content of the saikosaponin in the bupleurum is further improved, and the saikosaponin is easier to dissolve out under the alkaline condition, so the dissolution rate of the saikosaponin in the bupleurum can be improved.
On the basis of the technical scheme, the invention can be further improved as follows:
further, the raw radix bupleuri decoction pieces in the step (1) are prepared by removing impurities and residual stems from raw radix bupleuri medicinal materials, cleaning, moistening, slicing into thick pieces and drying.
Further, the drying temperature was 58 to 63 ℃.
Further, in the step (1), the mass ratio of the radix bupleuri crude decoction pieces to the baking soda is 100: 1-6, and the concentration of the sodium bicarbonate aqueous solution is 60-100 g/L.
Further, the soaking time in the step (1) is 0.5-3 h.
Further, the temperature of the fire in the step (2) is 100-200 ℃.
Further, the time for frying dry in the step (2) by slow fire is 5-10 min.
The invention has the following beneficial effects: the prepared bupleurum root processed product has the content of the total saikosaponin which is about 2 times higher than that of the raw bupleurum root decoction pieces, and the content of the saikosaponin a and the saikosaponin d which is more than 2 times higher than that of the raw bupleurum root decoction pieces; as the bupleurum root is mainly used as a decoction in clinic, the dissolution rate of saikosaponin a and saikosaponin d in the prepared bupleurum root product is about 2 times higher than that of bupleurum root crude decoction pieces when the bupleurum root is decocted in water.
