Problems solved by technology

Since there is no general-purpose near-infrared technology, the patents and literature on the near-infrared online detection of Weisu granule extraction process have not yet been reported
In addition, the current determination of the content of the traditional Chinese medicine Weisu granule extract is determined by high-performance liquid chromatography. The process of this method is complicated and cumbersome, and the detection cycle is long. The content information of the active ingredients cannot be fed back in time, which is not conducive to the uniformity and stability of the quality of the drug.

Embodiment 1

[0061] For the prescription composition of this embodiment, refer to Embodiment 1 of patent CN200510038872.

[0062] The preparation method of the extract is to extract the volatile oil from the six flavors of perilla stalk, Cyperus cyperi, dried orange peel, citron, bergamot and Fructus aurantii, and store in another container. The dregs are decocted with betel nut and gallinacea with water twice, the decoction process continues to collect volatile oil, filtered, combined filtrates, and concentrated to obtain the product.

[0063] Install a near-infrared online detection system: a near-infrared online detection pipeline is designed. The near-infrared detection pipeline opens from the outlet of the extraction large circulation, and the liquid is transported upwards through a centrifugal pump. Near-infrared pretreatment system such as figure 2 shown.

[0064] The modeling work is as follows: first open the first valve (1), the third valve (3), the fourth valve (4), the fifth...

Abstract

The invention discloses a near infrared detection method in a Weisu granule extraction process. The near infrared detection method comprises the step of determining contents of effective ingredients, namely naringin, hesperidin and neohesperidin, in each time period of different batches in an extraction process. According to the invention, a method for carrying out online analysis on the content of each index component in the Weisu granule extraction process is established and is applied to online detection, real-time monitoring on the content of each index component in the Weisu granule extraction process is realized, and the quality control level and production efficiency in the Weisu granule extraction process are improved.

Description

technical field [0001] The invention relates to the field of medicine, in particular to an online near-infrared detection method and application of the Weisu granule extraction process. Background technique [0002] In order to realize the quality control of the production process of traditional Chinese medicine products and ensure the stability and controllability of the efficacy of traditional Chinese medicine products, comprehensive monitoring must be carried out from the pretreatment, extraction, concentration, preparation and other aspects of the medicine. The existing analysis technology process is complex and cumbersome, the detection cycle is long, and the content information of active ingredients cannot be fed back in time. In order to effectively control product quality, improve production efficiency, and better save costs, the key technology of online quality control in the production process is imperative. [0003] Weisu Granules is a formula based on 50 years o...
