Embodiment 1
[0017] Determination of Paeonol in Cut Tobacco
[0018] a. Weigh 40g of shredded cigarette tobacco sample, add chloroform-absolute ethanol (1:1, V / V) 400mL to the flask, soak overnight at room temperature, extract ultrasonically for 15min, cool to room temperature, filter, and extract Wash the shredded tobacco and container 3 times with 3×50mL, and combine the filtrates.
[0019] b. Concentrate the obtained filtrate to dryness at 20kPa, dissolve the residue with 40mL of methanol, and dilute to 50mL to obtain the test sample.
[0020] c, HPLC analysis is carried out to obtained sample.
