Embodiment 1
[0054] 1. Preparation of the test solution: take about 2.0 g of the sample, accurately weigh it, put it in a stoppered conical flask, add 25 ml of 75% methanol accurately, weigh it, extract it by ultrasonic extraction for 30 minutes, let it cool, and weigh it again. Determine the weight, make up the lost weight with 75% methanol, shake well, filter, and take the filtrate to obtain the final product.
[0055] 2. Preparation of reference substance solution: take puerarin, caffeic acid, daidzin, rosmarinic acid, hesperidin, daidzein reference substance, accurately weighed, add methanol to prepare a concentration of puerarin 90.0 μg / ml, A mixed reference solution of caffeic acid 52.6 μg / ml, daidzin 127.2 μg / ml, rosmarinic acid 80.4 μg / ml, hesperidin 19.1 μg / ml, daidzein 42.8 μg / ml.
[0056] 3. High performance liquid chromatography conditions: the chromatographic column uses octadecylsilane bonded silica gel as filler; the detection wavelength is 280nm; the column temperature is 2...

[0065] 1. Preparation of the test solution: take about 0.5g of this product, accurately weigh it, put it in a stoppered conical flask, add 15ml of 50% methanol accurately, weigh it, extract it by ultrasonic extraction for 15 minutes, let it cool, and then Weigh the weight, make up the lost weight with 50% methanol, shake well, filter, and take the filtrate to obtain the final product.
[0066] 2. Preparation of reference substance solution: take puerarin, caffeic acid, daidzin, rosmarinic acid, hesperidin, daidzein reference substance, accurately weighed, add methanol to prepare a concentration of puerarin 90.0 μg / ml, A mixed reference solution of caffeic acid 52.6 μg / ml, daidzin 127.2 μg / ml, rosmarinic acid 80.4 μg / ml, hesperidin 19.1 μg / ml, daidzein 42.8 μg / ml.
[0067] 3. High performance liquid chromatography conditions: the chromatographic column uses octadecylsilane bonded silica gel as filler; the detection wavelength is 270nm; the column temperature is 20°C; acetonitri...
Embodiment 3
[0076] 1. Preparation of the test solution: take about 5.0 g of this product, accurately weigh it, put it in a stoppered conical flask, add 50 ml of 100% methanol accurately, weigh it, extract by heating and reflux for 60 minutes, let it cool, and then Weigh the weight, make up the lost weight with 100% methanol, shake well, filter, and take the filtrate to obtain the final product.
[0077] 2. Preparation of reference substance solution: take puerarin, caffeic acid, daidzin, rosmarinic acid, hesperidin, daidzein reference substance, accurately weighed, add methanol to prepare a concentration of puerarin 90.0 μg / ml, A mixed reference solution of caffeic acid 52.6 μg / ml, daidzin 127.2 μg / ml, rosmarinic acid 80.4 μg / ml, hesperidin 19.1 μg / ml, daidzein 42.8 μg / ml.
[0078] 3. High performance liquid chromatography conditions: the chromatographic column uses octadecylsilane bonded silica gel as filler; the detection wavelength is 290nm; the column temperature is 40°C; acetonitrile...
