GB/T 6682 Specifications and test methods for water used in analytical laboratories

3 Terms and definitions

There are no terms or definitions that require definition in this document.

4 Principle

The lycopene in the non-microencapsulated sample was extracted or dissolved by an organic solvent to obtain a sample solution; the microencapsulated sample was treated with an ammonia-phosphate buffer solution After the cell wall was broken, the lycopene in the sample was dispersed into the solution, and tetrahydrofuran was added to dissolve it to obtain the sample solution. The products were separated by HPLC and detected by UV detector. The products were qualitatively identified by retention time and quantitatively identified by external standard method.

5 Reagents or materials

Unless otherwise specified, only analytical grade reagents were used. 5.1 Reagents 5.1.1 Water. Grade 1 water as specified in GB/T 6682. 5.1.2 Ethanol (C2H5OH). 5.1.3 Petroleum ether. boiling range 60℃~90℃. 5.1.4 N,N-Dimethylformamide (C3H7NO). chromatographically pure. 5.1.5 Preparation of ammonia-phosphate buffer solution. Measure 143 mL of ammonia water, add it to 857 mL of water, mix well, and adjust the pH to 5.5 with phosphoric acid. 9.8±0.1. 5.1.6 Preparation of 0.025% 2,6-di-tert-butyl-p-cresol (BHT) tetrahydrofuran solution. Weigh 0.25 g (accurate to 0.1 mg) of BHT and Add tetrahydrofuran to 1 L and mix well. 5.1.7 Preparation of 0.5% BHT dichloromethane solution.
