Analysis of Taxus cuspidata twigs and leaves by HPLC-FPS / 中草药

ABSTRACT

Objective To study the HPLC fingerprints (HPLC-FPS) Taxus cuspidatea twigs and leaves (TCTL) for reflecting the internl chemical information and evaluating its internal quality of TCTL. Methods HPLC was used to analyze the alcohol extracts of TCTL. Results The fingerprint of TCTL was established. HPLC-FPS of ten batches of T. cuspidata samples collected at different time were analysed and extablished. The correlation technicl parameters of T. cuspidata were obtained, i.e. the main common peak with relative retention time and relative peak area. Conclusion The fingerprint can be used to evaluate the quality of TCTL.
