And use Ethanol to extract the flavonoid from the waxberry pit, do verifying of the flavonoid, which is extracted from the waxberry pit. Use absorp-tion of the ultraviolet to test the flavonoid content, At last, use the dilute method to add the flavonoid into the toffee grandually according to the toffee processing technics. Then we can obtain the waxberry pit toffee, that is health flavonoid toffee. Experiment result is that waxberry pit can not dissolve well with the toffee materials, use extracted flavonoid and add into the milk suguar is the best way to process the waxberry pit toffee ,and the color of sugar was changed by flavonoid, the best extraction plan to obtain the flavonoid is use 80% ethanol in the 3 hours calefaction at 60 ℃ water bathses. 关键词:杨梅核;总黄酮;奶糖; Keyword: waxberry; flavonoids ; Toffee;
