Embodiment 1
[0055] In the following examples and experimental examples, the preparation method of Radix Paeoniae Alba Formula Granules is:
[0056] Take Radix Paeoniae Alba, heat and reflux to extract twice, add 8 times the weight of water for the first time to extract for 1.5 hours, add 6 times the weight of water for the second time, extract for 1 hour, filter, combine the filtrates, and concentrate the filtrates to a relative density of 60°C The liquid extract is 1.05-1.10, adding conventional auxiliary materials, and making granules according to the conventional process. ,
Embodiment 2
[0058] The present embodiment establishes the method for the fingerprint of Radix Paeoniae Alba formula granule, comprises the following steps:
[0059] (1) Take 0.10g of white peony formula granules to be tested, accurately weighed, accurately add 20mL of dilute ethanol, weighed, heat reflux extraction or ultrasonic extraction for 30 minutes, let cool, weigh again, take dilute ethanol to make up for the lost Shake up, filter, get continued filtrate, as need testing solution;
[0060] (2) Accurately weigh the reference substance of paeoniflorin, add methanol to make a solution containing 0.00006g per 1mL, shake well, and use it as the reference substance A solution;
[0061] Precisely weigh paeonifloride reference substance, add methanol to make a solution containing 0.0010g per 1mL, shake well, and use it as reference substance B solution;
[0062] Precisely weigh hydroxypaeoniflorin reference substance, add methanol to make a solution containing 0.00013g per 1 volume part, ...
Embodiment 3
[0067] The present embodiment establishes the method for the fingerprint of Radix Paeoniae Alba formula granule, comprises the following steps:
[0068] (1) Take 0.05g of Radix Paeoniae Alba Formula Granules to be tested, accurately weighed, accurately add 30mL of dilute ethanol, weighed, heat reflux extraction or ultrasonic extraction for 20 minutes, let cool, weigh again, take dilute ethanol to make up for the lost Shake up, filter, get continued filtrate, as need testing solution;
[0069] (2) Accurately weigh the reference substance of paeoniflorin, add methanol to make a solution containing 0.00010g per 1mL, shake well, and use it as the reference substance A solution;
