Two-stage cross-flow centrifugal extraction control system and method for extracting sinomenine

Abstract

The invention provides a two-stage cross-flow centrifugal extraction control system and method for extracting sinomenine. A control device of the two-stage cross-flow centrifugal extraction control system comprises a first extract liquid transfer pump, a second extract liquid transfer pump, a first liquid concentration detecting sensor, a second liquid concentration detecting sensor and a controller; the first liquid concentration detecting sensor is used for detecting a concentration of an extract liquid extracted by a first-stage centrifugal extractor; the second liquid concentration detecting sensor is used for detecting a concentration of an extract liquid extracted by a second-stage centrifugal extractor; and the controller is used for controlling the first extract liquid transfer pump and the second extract liquid transfer pump to output an extract liquid meeting a concentration requirement to the interiors of a first extract liquid receiving tank and a second extract liquid receiving tank according to the concentrations of the extract liquids detected by the first liquid concentration detecting sensor and the second liquid concentration detecting sensor. The two-stage cross-flow centrifugal extraction control system and method for extracting the sinomenine provided by the invention have a high automation degree and high extraction precision of the sinomenine.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of the pharmaceutical industry, in particular to a two-stage cross-flow centrifugal extraction control system and method for extracting sinomenine. [0003] 【Background technique】 [0004] Sinomenine is the main active ingredient in the herbal medicine of Fangjiaceae, Qingfengteng. It has anti-inflammatory, analgesic, anti-rheumatic and immunosuppressive effects. One of the strongest histamine releasers known in plants. In the prior art, the extraction of sinomenine from C. chinensis generally adopts the reflux extraction method. The content of sinomenine in C. chinensis is relatively high, and its basic nucleus is morphinane, which has good fat solubility. [0005] The production process in the prior art is as follows: take Teng chinensis, carry out heavy percolation with dilute hydrochloric acid, alkalinize the percolation liquid, centrifuge, then extract twice with chloroform, concentrate and cr...
