Objective: To optimize ultrasonic extraction technology of antitumor diterpenoid from Pteris dispar. Method: Four factors of the concentration of ethanol
extraction time
extraction times and solid-liquid ratio were investigated by L9(34) orthogonal design test
the content of ent-11α-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F) was defined as index
the content of 5F was determined by HPLC. Result: A2B2C3D3 was optimum ultrasonic extraction technology
which was ultrasonic extracted 3 times with 12 times the amount of 75% ethanol by 65 min each time. Conclusion: This optimized process was stable and available.
