Abstract:
Object To establish the process of purification for ?-linolenic acid from the fruit oil of Camptotheca acuminata Decne.. Methods Complexometry by AgNO 3 was applied. Results The optimal conditions: the AgNO 3 concentration was 4 mol/L, the complexometric temperature was lower than 15 ℃, and the complexometric time was 2 h. The purity of ?-linolenic acid was 91.25%. Conclusion The concentration of ?-linolenic acid from the fruit oil of C. acuminata can reach to 45.8%, therefore it is a new abundant resource for ?-linolenic acid. ?-linolenic acid can be well purified in the fruit oil by this process.
