Embodiment 1
[0029] (1) Weigh 10g of cosmetics in quantitative filter paper, continuously extract with absolute ethanol, place the extracted residue at 100°C, and blow off the solvent until the residue weighs;
[0030] (2) Continuously extract the above residue with hexane, extract the residue at 100° C., and blow off the solvent until it reaches a constant weight;
[0031] (3) The hexane extraction residue was continuously extracted with tetrahydrofuran, and the insoluble residue was kept at 110° C. until the residue was at a constant weight;
[0032] (4) pulverize the residue extracted by tetrahydrofuran until the particle size is less than 320 mesh;
[0033] (5) Use the D / max-rA X-ray diffraction instrument to scan the sample in the fourth step under the conditions of 40Kv / 30mA, rotating anode CuKa, and Ni filter, and print the spectrum.
[0034] figure 1 is the X-ray spectrum of the sample, figure 2 It is pure sample standard spectrum
[0035] It can be seen from the X-spectrum sp...
Embodiment 2
[0037] (1) Weigh 10g of cosmetics in quantitative filter paper, continuously extract with absolute ethanol, place the extracted residue at 110°C, and blow off the solvent until the residue weighs;
[0038] (2) Continuously extract the above residue with hexane, extract the residue at 90° C., and blow off the solvent until it reaches a constant weight;
[0039] (3) Continuously extract the hexane extraction residue with tetrahydrofuran, and place the residue at 110° C. to dry until the residue has a constant weight;
[0040] (4) pulverize the residue extracted by tetrahydrofuran until the particle size is less than 320 mesh;
[0041] (5) The residue extracted by tetrahydrofuran and potassium bromide are compressed into tablets at a weight ratio of 1: 150-200, and the resolution is Δγ=4cm-1,64 under the condition of Nicolet Magna 550 Fourier infrared spectrometer Scan the sample in step 4 and print the spectrum.
