Processing method of radix polygonum multiflorum preparata

Abstract

The invention relates to a processing method of radix polygonum multiflorum preparata. The processing method comprises the steps of picking, wherein medicinal materials of radix polygonum multiflorum are taken and picked, and impurities are removed; cleaning; steaming, wherein the cleaned radix polygonum multiflorum is put into a cooking pot, steam is introduced for steaming, and after steaming is completed, medicine juice is collected; pre-drying, wherein the steamed radix polygonum multiflorum is taken out and put in an oven to be dried until the moisture content of the radix polygonum multiflorum is 10-15%; cutting, wherein the radix polygonum multiflorum is taken out, and cut into thick slices by a turntable-type slicer, and each slice is 2 mm in thickness; medicine moistening, wherein the collected medicine juice is uniformly mixed into the sliced radix polygonum multiflorum, after the radix polygonum multiflorum is moistened and completely absorbs the medicine juice, the treated radix polygonum multiflorum is put into the oven, the drying temperature is 60-70 DEG C, the drying time is 2-4 hours, and after drying, the moisture content of the radix polygonum multiflorum is 10% or below. According to the processing method, the steaming time is moderate, so that the content of stibene glucoside is significantly increased.

Description

technical field [0001] The invention relates to a preparation method of Chinese herbal medicine, in particular to a processing method for preparing Radix Polygoni Multiflori. Background technique [0002] For the processing method of Radix Polygoni Multiflori, in prior art, generally be to use black soybean to mix steaming method, nine steaming and nine drying methods etc. The disadvantage of the prior art is that after the black beans are mixed and steamed, the contents of emodin and emodin methyl ether both in the methanol solution and the ether solution all decrease, and the longer the processing time, the more the reduction. The content of stilbene glycosides also decreased with the extension of steaming time. The steaming time is too long, which affects the output of active ingredients. [0003] In the 2015 edition of the "Chinese Pharmacopoeia", there are also two methods of preparation, which are steaming method with black soybean juice and steaming method. The disa...

The steaming time is too long, which affects the output of active ingredients

[0003] In the 2015 edition of the "Chinese Pharmacopoeia", there are also two methods of preparation, which are steaming method with black soybean juice and steaming method. The disadvantages of these two methods are that the production efficiency of the process is low, the yield is low, and the energy consumption is large. large-scale industrial production

Chinese patent document CN107308218A discloses a nine-steamed and nine-processed Polygonum multiflorum processing method, which has complicated process and various conditions, requires nine steamed and nine-processed processes, repeated steaming, many steps, long processing time, low efficiency, and high energy consumption. high cost
