Embodiment 1
[0128] 1. Take 4Kg of refined shea olein with AV=0.5, triterpenoid alcohols and sterol content of 7.20%, add methanol and milk with a mass ratio (refined shea oil:methanol) of 3:1 Sodium methoxide with 0.7% quality of the fruit liquid oil, reacted at 70°C for 2.5 h, separated the liquid, took the upper liquid, washed with water, stood still to separate the liquid, took the upper liquid, and distilled under reduced pressure to remove the residual solvent to obtain the transesterification product. The yield was 92.0%, and the content of triterpene alcohols and sterols was 7.13%.
[0129] 2. Take 1kg of the shea olein transesterification product obtained in the previous step, and carry out molecular distillation at a distillation temperature of 110°C, a rotational speed of 250rpm, and a pressure of 10 -3 mbar. A 130 g heavy phase sample was obtained by distillation, and the content of triterpene alcohols and sterols was 50.86%. (The specific content of unsaponifiable matter in ...
