The invention provides whole blood RNA quick lysate which does not need erythrocyte pyrolysis firstly, and an RNA extraction method. According to the method, the usage of toxic reagents is reduced toa large extent, RNA extraction steps are simplified, and RNA obtained through purification is good in integrity and high in purity and can be directly used for various molecular biology experiment ofRT-PCR, Northern blot, Dot blot and the like. Every 1000ml by volume of the whole blood RNA quick lysate disclosed by the invention consists of the following components by dosage of 0.2M-4M of guanidine thiocyanate, 0.2M-3M of ammonium thiocyanate, 0.01M-0.2M of anhydrous sodium acetate, 0.05M-0.3M of glacial acetic acid, 0.1%-2%(W/V) of sodium lauroyl sarcosine, 0.02M-0.3M of sodium chloride, 1%-15%(V/V) of glycerine, 10%-75% (V/V) of a water saturation phenol solution, and the balance DEPC treating water.
