The invention relates to the technical field of monitoring of preparation processes of natural
plant chemical components, and discloses a real-time monitoring and
analysis method for an extraction process of medicinal
plant total flavonoids, which is characterized in that in the extraction process of the medicinal
plant total flavonoids, the
ethanol concentration, the material-to-
liquid ratio, the extraction duration and the
granularity are compared for many times; the
ethanol concentration, the material-
liquid ratio, the extraction time length and the
granularity concentration in the extraction process of the medicinal plant total flavonoids are determined. According to the real-time monitoring and
analysis method for the extraction process of the medicinal plant total flavonoids, the process parameters of the
ethanol concentration, the material-to-
liquid ratio, the extraction duration and the
granularity in the ethanol extraction process of the medicinal plant total flavonoids are monitored to judge whether the requirements are met or not, and self-adaptive adjustment is carried out; the problem that the extraction rate of the total flavonoids is too low due to too large deviation of technological parameters of ethanol extraction of the total flavonoids of the
medicinal plants is avoided, the stability of the ethanol extraction rate of the total flavonoids of the
medicinal plants is guaranteed, and then the product quality is guaranteed.
