Objective: To investigate the influences of the natural vitamin E on stability of Angelicas Sinensis Radix Oil
and provide scientific basis to ensure the stability of preparations made from Angelicas Sinensis Radix Oil. Method: Isothermal acceleration was taken with initial average rate method to detect the change of the refractive indexes. Rusult: At 293 K
the time of Angelicas Sinensis Radix Oil resolved 10%
20%
30% was t0.9=8.68 d
t0.8=18.37 d
t0.7=29.36 d;after added 0.01-1 natural vitamin E
the resolve time extended to t0.9=22.25 d
t0.8=47.10 d
t0.7=75.29 d. Conclusion: The stability of Angelicas Sinensis Radix Oil advanced 2.56 times after added 0.01∶1 natural vitamin E. The natural vitamin E could obviously enhance the stability of Angelicas Sinensis Radix Oil.
