The invention relates to a tea leaf aroma extraction method comprising the following steps of: (1) extracting the tea leaf aroma by taking microwave as a heat source to obtain a tea leaf aroma extracting solution; and (2) carrying out vacuum concentration on the tea leaf aroma extracting solution to obtain a concentrated solution; filtering the concentrated solution to obtain a filtrate; adsorbing the filtrate by using silver nitrate complex silica gel, and then, eluting by using absolute ethyl alcohol to obtain a tea leaf aroma eluant, namely tea leaf aroma. According to the method provided by the invention, the microwave is used as the heat source, the longest extraction time is up to 60minutes, and therefore, the possibility of generating bad flavor is greatly reduced, and the yield is increased by 2-3 times as comparison with that of the traditional steam distillation method; and in addition, the method is short in treatment time, simple in steps and capable of shortening the pretreatment time.
