结果表明，其最佳浸提方案是：成品茶样经粉碎过40目（0.45mm）筛，称取样品3g茶样用400ml沸蒸馏水冲泡，置于100℃恒温水浴锅中浸提30min后抽滤定容至500ml，而后用茚三酮比色法测定其含量。

• Results showed that the best extracted design was: the baked green tea was sifted through a 0.45 mm sieve, the 3 g of sample tea were infused by 400 ml boiling deionized water, and extracted in boiling water bath for 30 min and then the extraction was sucked with suction pump and settled to the volume of 500 ml.
