clove oil - Differential diagnosis
Authoritative Data Verified Data
- take about 80 m g of this product, add 2M l of toluene to dissolve, as a test solution. In addition, an appropriate amount of a control substance of eugenol and eugenol acetate was taken, and a mixed solution containing 25mg each in 1 μl of toluene was prepared as a control solution. According to the thin layer chromatography (General 0502) test, draw 2u1 of each of the above two solutions, respectively point on the same silica gel GF254 thin layer plate, with toluene as the developing agent, expand and take out, after placing for 5 minutes, perform the second unfolding, take it out, dry it, and examine it under a UV lamp (254nm), the chromatogram of the reference solution should show two clearly separated spots (the spots are eugenol and eugenol acetate from top to bottom), the position and color of the dominant spots in the chromatogram of the test solution should be the same as the spots of eugenol and eugenol acetate in the control solution. Then spray with anisaldehyde solution (anisaldehyde 0. 5ml, add glacial acetic acid 10ml to dissolve, add methanol 85ml and sulfuric acid 5ml, shake, then get. In the new system), heated at 105°C for 5 to 10 minutes, the position and color of eugenol and eugenol acetate in the chromatogram of the test solution should be the same as those of eugenol and eugenol acetate in the reference solution, below the solvent front and the eugenol acetate spot, one red spot should be shown, the solvent front spot being B- syringene.
- in the chromatogram recorded under the content determination item, the retention time of the main peak of the test solution should be the same as that of the control solution/3-syringene peak, the retention times of eugenol and eugenol acetate peaks were consistent.
above (1), (2) two items can be done one.
