p style"text-aligned: center; height: 84px
; This product is a light yellow to orange red clear, transparent liquid, can be mixed in petroleum ether, ether, chloroform, acetate, ethanol, acetone
"Identification" take this product plus ethyl acetate to make 0.5% solution for test solutionTake the standard products of methyl positive ketone, acetaldehyde, laurylene, lemonene and other ethyl acetate made into each containing 10 sl /ml solution for control liquidTake fishy grass standard control herbs 1.0g with acetone 30 ml, ultrasonic extraction for 30 minutes, the filtrate cold wind blows off acetone plus ethyl acetate 1 ml dissolved as a control liquidTake the above three liquids each 5 sl, respectively, point on the same silicone G board, to cyclhexane-ethyl ethyl (9:1) to expand, spray dinitrobenzene test liquidThe corresponding location of the label spot shows the same color spot, compared to the standard medicinal spot, the corresponding rate is 60%
