RESUMEN

Objective To apply accelerated solvent extraction (ASE) technique to extract Achyranthes bidentata and to explore the application of this technique in quality control of Chinese materia medica. Methods Investigation of single factor was used to optimize the conditions that affected the efficiency for ASE from A. bidentata by RP-HPLC using ecdysterone as a quantitative marker. Results The optimized conditions for ASE of A. bidentata were obtained as follows: methanol as solvent, particle size between 0.3 and 0.45 mm, temperature at 100 ℃, pressure under 10.34 MPa, 6 min duration and once extraction. Conclusion ASE technique can be used to extract A. bidentata quickly and effectively.
