Embodiment 1
[0039] The content determination of ferulic acid in the angelica medicinal material of embodiment 1
[0040] See Table 1 for the source and place of origin of the tested angelica medicinal materials. They were numbered and detected according to different batches. The specific steps of the detection are as follows:
[0041] (1) Accurately weigh 10 mg of ferulic acid reference substance, put it in a brown measuring bottle, add 70% methanol to dissolve and dilute to 50 mL; accurately measure 3 mL of the solution, add 70% methanol to dilute to 50 mL, shake well to obtain The reference substance solution of 12 μ g ferulic acid;
[0042] (2) Accurately weigh 0.2g of Angelica sinensis medicinal material powder to be tested, add 20mL of 70% methanol, weigh it, heat and reflux for 30 minutes, let it cool and then weigh it, and use 70% methanol to make up for the lost weight, and take it after standing. The supernatant is filtered with a microporous membrane, and the subsequent filtrat...
