Study on HPLC fingerprint of Taxus chinensis var. mairei

Objective: To establish the HPLC fingerprint of Taxus chinensis var. mairei collected from different parts during different seasons and provide scientific basis for its comprehensive utilization. Methods: Supercritical CO2extraction was used to extract the effective fraction, HPLC method to establish the fingerprint and similarity evaluation software to analyze the fingerprint chromatogram. Results: 12 batches of Taxus chinensis var. mairei medicinal materials from different parts collected in different seasons were analyzed and HPLC fingerprint of Taxus chinensis var. mairei was established. Conclusion: The HPLC fingerprint can be used to evaluate the quality of Taxus chinensis var. mairei medicinal materials.
