Embodiment 1
[0060] Example 1 Determination of fingerprints of bufadiene components in toad venom
[0061] 1 Experimental part
[0062] 1.1 Sample pretreatment
[0063] Preparation of the test solution: Accurately weigh 0.2g of toad venom fine powder, accurately add 20ml of methanol, weigh, ultrasonically extract, after cooling, weigh again, make up for weight loss with methanol, shake well, filter, and take the filtrate As the test solution.
[0064] Preparation of reference substance solution: Accurately weigh an appropriate amount of reference substances of bufafetalin, bufafetalin, bufafolin, cinobufafolin base, and lipobufagenin reference substance respectively, add methanol to dissolve and constant volume, and shake well to obtain Mix the reference substance solution; wherein, the content range of each component is: bufafetalin 151.2-226.8 μg, bufafetalin 225.6-451.2 μg, bufafolin 171.6-343.2 μg, cinobufacyl 460.0-9200.0 μg, Repobugenin 394.4 ~ 788.8μg.
