Automatic judgment and control for eluant receiving of buckeye extract

Abstract

The invention provides an automatic detection and control method of elusion start points and end points during macroporous resin purification of buckeye extract. An aescin macroporous resin purification near-infrared calibration model is built by using total content of aescin as evaluation index, the calibration model is used in online detection of buckeye extract macroporous resin elusion, and accordingly automatic judgment of elusion start points and end points during macroporous resin purification of buckeye extract is achieved, and automatic control of eluant receiving and receiving stopping is achieved. The method is fast, accurate, high in automation level and the like, manual errors are reduced, the problem that products of different batches are poor in quality uniformity is solved, effective component loss and waste can be avoided effectively, and a new technique is provided for automatic control and process quality control during macroporous resin purification of buckeye extract.

Description

technical field [0001] The invention relates to an automatic control in the production process of Zhongyue, in particular to an automatic judgment and control of the starting point and the end point of the eluate received by the extract of salsa seeds during the elution process of the macroporous resin. Background technique [0002] Aescin is a mixture containing more than 30 kinds of saponins extracted and separated from the Chinese herbal medicine Suluozi. It belongs to the triterpenoid saponins, and aescin A, B, C, and D are its main active ingredients. Salazi comes from the dry mature seeds of Aesculus aesculus or Tianshi Chestnut. It is sweet and warm in nature and returns to the liver and stomach meridian. Its main functions are soothing the liver and regulating qi, harmonizing the stomach and relieving pain. , chest and abdomen distension, epigastric pain. Aescin is the most important active ingredient of the traditional Chinese medicinal material Salazi. Modern medi...

Problems solved by technology

[0005] The invention provides a near-infrared on-line detection method and an automatic control system for the elution process of the extract of the salsa seed in the macroporous resin, which realizes the change of the content of various active ingredients as the monitoring index in the elution process as the starting point for receiving the eluent Rapid judgment and automatic control of end point and end point, thus overcoming the problem of poor quality uniformity of different batches of products, avoiding loss and waste of active ingredients, and saving labor costs, suitable for industrialized mass production
