Rapid and undamage determination of fruit of Eucalyptus globules labill by near infrared spectroscopy and clustering analysis / 中成药

ABSTRACT

AIM: To provide a rapid method for identifying fruit of Eucalyptus globule labill. METHODS: A new method, using NIRS for rapid and nondestructive classfication of the fruit of Eucalyptus globules labill and its counterfeit drug, the fruit of Eucalyptus robusta Smith, was proposed and then cluster analysis was adopted. RESULTS: The result showed that two kinds of fruits had their own characteristic NIRS spectra. CONCLUSION: The method is quick, simple and reliable, and in combination of the fingerprint NIRS spectrum and the clustering analysis is easy to identify the adulteration.
