Objective: To predict shelf life of Aconiti Radix Cocta and provide basis for assessing its quality. Method: Contents of benzoylaconine
benzoylhypacoitine
benzoylmesaconine
aconitine
hypaconitine and mesaconine were determined by HPLC
with acetonitrile(A)-40 mmol·L-1 ammonium acetate(B) (0-45 min
30%-45%A;45-65 min
45%-50%A;65-75 min
50%-55%A;75-80 min
55%-65%A;80-85 min
65%A) as mobile phase by gradient eluting
detection wavelength was set at 240 nm.Initial average rate test was adopted to predict shelf life
contents change of diester alkaloids and monoester alkaloids in Aconiti Radix Cocta under different temperature were investigated. Result: Shelf life of Aconiti Radix Cocta had been determined as 0.69 years. Conclusion: High temperature was not conducive to stability of Aconiti Radix Cocta
initial average rate test could provide a reference for establishing validity of herbs.
