Objective: To establish the UHPLC fingerprint and quantitative analysis of CBDA, CBD, THC, and THCA for hemp, and provides a basis for the quantity control of hemp. Methods: UHPLC was launched on a Phenomenex C18 (150 mm×4.6 mm, 2.6 μm) with mobile phase of acetonitrile-0.2% phosphoric acid aqueous solution at a flow rate of 1.0 mL · min-1, column temperature of 35 ℃, detection wavelength of 220 nm, and an injection volume of 2 μL by gradient elution. 15 batches of hemp samples from Daxing ’anling region and Qiqihar were analyzed to establish the fingerprint. Cluster analysis, principal component analysis and orthogonal partial least squares discriminant analysis were adopted to assess of UHPLC fingerprint of hemp. Results: the UHPLC fingerprint of hemp was established, and 26 common peaks were selected the 26 common peaks were compared with the reference substance. The structures of four chromatographic peaks were identified and simultaneously analyzed for content determination. four chromatographic peaks were identified as CBDA, CBD, THC and THCA.The similarity of fingerprint of them was greater than 0.950. The samples from Daxing’anling were clustered into class Ⅰ, with the best quality. The results show that hemp samples from different regions were quite different. The variable importance projection (VIP) showed that the four compounds to be tested were the main components leading to the difference of hemp. Conclusion: The established method is stable and reliable and can be used for qualitative and quantitative analysis of hemp. The findings of this study are expected to provide a scientific basis for quality control of hemp.
