[description] this product as yellow or brown yellow clear liquid; the specific aroma of cinnamon, sweet, bitter, dew set in the air or stored for a long time, color depth gradient, thickened. This product is soluble in ethanol or acetic acid. The relative density is 1.055 ~ 1.070 (Appendix VII A). Refractive index should be 1.602 ~ 1.614 (Appendix VII F). [identification] to take this product, cooling to 0 degrees Celsius, and other capacity of the nitrate shake, that is, the precipitation of crystalline precipitation. [content] according to gas chromatography (Appendix VI B) determination. The chromatographic conditions and system suitability tests with polyethylene glycol (PEG) -20M as the stationary phase, the coating concentration is 10%; the column temperature is 190. The number of theoretical plates should not be less than 3000 calculated by the peak of cinnamaldehyde. The control of sample solution prepared from cinnamic aldehyde control amount of goods, precision, and anhydrous ethanol made from containing 4 mg per ml of solution. Tested sample solution preparation to take this product about 50mg, precision, is placed in a 10 ml volumetric flask, add anhydrous alcohol to scale. Strain. Determination of 3 L in the solution of the control solution and the solution of the test sample were respectively. This product contains cinnamic aldehyde (C9H8O) shall not be less than 75%.
