Objective: To establish variation relationship equation between alkaloids content and time in processing process of Aconiti Radix. Method: Aconiti Radix Cocta samples were prepared by pressurized steaming method
the content of six kinds of alkaloids in each sample was determined by HPLC
and optimum processing time was estimated by curve fitting of their content-time trend. Result: After Aconiti Radix was processed 15-150 min at 111 ℃(0.05 MPa)
fitting regression equation of variation relationship curve between diester alkaloids content in Aconiti Radix Cocta with processing time was C=0.273+0.236×lnt(R2=0.753
F=48.818
P<0.01)
monoester alkaloids was C=0.115×t-0.005(R2=0.850
F=90.660
P<0.01). Conclusion: This established method provided a theoretical support about fast processing Aconiti Radix and estimating processing time of Aconiti Radix.
