Abstract
The influence of saponification method,the content of sodium hydroxide in the process of saponification,saponification temperature,saponification time and antioxidants TBHQ usage in the process of extracting with three kinds of health food as the research object.Results show that 120 ℃ ± 2 ℃,sand bath,adding sodium hydroxide in the process of saponification 60 g,saponification temperature is 120 ℃,saponification time is 35 minutes and in the process of extracting antioxidants TBHQ dosage of 0.02% 10 ml,the sample has the very good recovery rate and precision,the recovery rate of D2 and D3 were 92.5% and 93.7%;precision of D2 and D3 were 1.7% and 1.3%.关键词
