Embodiment Construction

[0010] The present invention uses ultrasonic technology to extract matrine in traditional Chinese medicine. The process steps of the present invention are as follows: crush flavescens into 40-mesh powder with a plant grinder, and add ethanol with a material-to-liquid ratio of 1:5 to 1:20. , the ethanol concentration is 60-95%, the soaking time is 1-5h, and then the ultrasonic extraction is performed at an ultrasonic power of 400w for 10-40min.

[0011] As a preferred solution, the process parameters of the present invention are: solid-liquid ratio 1:10, soaking time 3 hours, ethanol volume fraction 80%, ultrasonic extraction time 20 minutes.

[0012] The present invention selects material-liquid ratio, ethanol volume fraction, soaking time, ultrasonic extraction time as the influencing factors of matrine extraction rate, and their influence on the extraction rate of Sophora flavescens can be seen, figure 1 , figure 2 , image 3 , Figure 4 .

Abstract

The invention relates to an extraction process of sophocarpidine and belongs to the field of processing of traditional Chinese medicines. The extraction process of sophocarpidine, which is provided by the invention, is short in time and good in extraction effect. The process provided by the invention comprises the following steps of: crushing sophora flavescens into 40-mesh powder by a plant crusher; adding ethanol with material-to-liquid ratio of 1:5-1:20, wherein the ethanol concentration is 60-95% and the soaking time is 1-5 hours; then, performing ultrasonic extraction for 10-40 minutes under the condition that the ultrasonic power is 400w; centrifugalizing the extraction liquid at a rotating speed of 3000r / min for 10 minutes; and taking supernatant liquid.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine processing, and more specifically relates to a process for extracting matrine. Background technique [0002] Sophora flavescens is a leguminous plant, which is distributed in all parts of China except Hainan, Xinjiang and Qinghai, and has high economic and medicinal value. At present, the domestic alkaloids extracted, separated and identified from Sophora flavescens mainly include oxymatrine, matrine, isomatrine, hydroxymatrine, sophocarpine, oxysophocarpine, sophoramine, sophocarpine Pyridine, aloperine, cytisine, N-methylcytisine, anagenine, indophyline, dehydromatrine, d-matrine, d-isomatrine, d -Alkaloids such as oxymatrine, l-swollenine, l-methylchrysantrine, l-indoline, matrine, sophoryl, oxysophorine, N-methylcydidine. [0003] At present, conventional methods for extracting matrine include decoction, water distillation, solvent extraction, etc. The extraction time is long, the...
