Embodiment Construction
[0022] The rapid assay method of feruloyl tyramide content in the lime provided by the invention, the method comprises the following steps and conditions:
[0023] (1) Chromatographic conditions: with octadecylsilane bonded silica gel as filler; methanol-0.4% phosphoric acid solution (35:65) as mobile phase; detection wavelength is 318nm; less than 1500;
[0024] (2) Preparation of reference substance solution: take an appropriate amount of feruloyl tyramide reference substance, weigh it accurately, add methanol to make a solution containing 143.6 μg per 1 mL, and obtain it;
[0025] (3) Preparation of the test solution: Take about 2 g of the powder of this product (passed through a No. 4 sieve), accurately weigh it, put it in a stoppered conical flask, add 25 mL of methanol precisely, seal it tightly, weigh it, and ultrasonically treat it ( power 250W, frequency 40kHz) for 30 minutes, let cool, weigh again, make up the lost weight with methanol, shake well, filter, and take ...
