Embodiment 1
[0036] In this example, the quantitative quality control of the herbal tea beverage was performed based on the contents of the characteristic components Danshensu, (α)-3-carboxy-α-hydroxyphenylpropionic acid (cerberic acid B) and rosmarinic acid as indicators.
[0037] (1) Preparation of reference solution:
[0038] Accurately weighed 11.25 mg of Danshensu reference substance into a 25 mL volumetric flask, added methanol-water with a volume ratio of 1:1, ultrasonically extracted for 20 min at 150 W, 40 KHz to dissolve and dilute to the mark, shake well, and prepare into 450 μg / mL Danshensu reference substance solution.
[0039] Accurately weigh 5.1 mg of (α)-3-carboxy-α-hydroxyphenylpropionic acid (cerberic acid B) reference substance into a 10 mL volumetric flask, add methanol, and ultrasonically extract for 20 min at 150 W, 40 KHz to dissolve and Dilute to the mark and shake well to make (α)-3-carboxy-α-hydroxyphenylpropionic acid (cerberic acid B) reference solution of 510...
Embodiment 2
[0057] In this example, the quantitative quality control of the raw material Prunella vulgaris extract is carried out with the content of the characteristic components Danshensu and Rosmarinic acid as indicators.
[0058] (1) Preparation of reference solution:
[0059] Accurately weighed 11.25 mg of Danshensu reference substance into a 25 mL volumetric flask, added methanol-water with a volume ratio of 1:1, ultrasonically extracted for 20 min at 150 W, 40 KHz to dissolve and dilute to the mark, shake well, and prepare into 450 μg / mL Danshensu reference substance solution.
[0060] Accurately weigh 10.4 mg of rosmarinic acid reference substance into a 50 mL volumetric flask, add methanol, and ultrasonically extract for 20 min at 150 W, 40 KHz to dissolve and dilute to the mark, shake well, and prepare a 208 μg / mL powder. Arnicic acid reference solution.
[0061] (2) Preparation of the test solution:
[0062] Take 0.1467 g of Prunella vulgaris extract, add 15 mL of water, wei...
