Abstract

The invention discloses an on-line ultraviolet analysis method for the dynamic tendency during extraction process of traditional Chinese medicines. The method comprises the steps of sampling in real time, detecting an ultraviolet reference spectrum and an extracting solution spectrum, obtaining the absorbancy, carrying out spectroscopy data pretreatment, calculating the absorbancy gradient, and the like; the method can be used for analyzing the dynamic tendency during the extraction process of the Chinese traditional medicines by analyzing the change situation of the absorbancy. According to the method, later off-line ultraviolet and the contents of solids are detected, so that the progress of the extraction process of the traditional Chinese medicines can be accurately reflected, the on-line quality control level during the process can be improved, quality information during the extraction can be quickly obtained in a non-destructive and real-time manner, the abnormal operation can be timely found and corrected, and the traditional Chinese medicines are safe, stable and effective.

Description

technical field [0001] The invention relates to online quality control and supervision of the extraction and production process of traditional Chinese medicines, in particular to an online ultraviolet analysis method for the dynamic trend of the extraction process of traditional Chinese medicines. Background technique [0002] In the rapid development of my country's traditional Chinese medicine pharmaceutical industry for many years, the modernization of traditional Chinese medicine has played a key role. The current production and processing process of traditional Chinese medicine includes extraction, concentration, separation, drying, drug forming and other operating units. The extraction of active ingredients is one of the key links in the production of traditional Chinese medicine. At present, there is basically no objective condition control and quality inspection in the extraction and production process of traditional Chinese medicine. It basically relies on manual exp...
