  • Method for detecting notoginseng using terahertz technology
    Patent number: 10837900
    Abstract: A method for detecting notoginseng using terahertz technology. The notoginseng samples are pulverized in pulverizer. The pulverized samples are mixed with polyethylene powder in the ratio of 1:4 to 1:6. The powder mixture is pressed in a tablet press to obtain notoginseng tablet. Terahertz spectrograph is started. A peak is saved, and a background signal is measured. The time-domain graph of the background without sample is acquired. The time-domain graphs of the notoginseng tablets are acquired. The time-domain graphs are transformed into frequency-domain graphs by Fourier transform. The frequency-domain graphs are converted to obtain absorption spectrum of the notoginseng tablets. The absorption peak position of test tablet is compared with that of standard tablet to determine its authenticity. The concentration of key active substances of the notoginseng test sample is quantitatively analyzed by integrating the area under absorption peak curve of the notoginseng test sample.
