Embodiment 1
[0029] Prescription: Yinchen 240g, Salvia miltiorrhiza 240g, Bupleurum 120g, Imperata 120g, Radix isatidis 120g, licorice 60g, jujube 60g.
[0030] Preparation method: add the above seven flavors, add water and decoct three times, combine the decoction, let stand, filter, concentrate the filtrate to a relative density above 1.30 (thermal measurement), add 240g of sucrose, heat to melt, mix well, concentrate to a relative density of 1.10 ~1.30, that is.
[0031] Properties: This product is brown thick semi-fluid, sweet and slightly bitter.
[0032] Inspection: the relative density is 1.10-1.30.
[0033] Composition identification and content determination:
[0034] (1) Identification of capillary and Artemisia annua: Take 1g of this product, add 8ml of methanol, ultrasonically treat for 20 minutes, filter, evaporate the filtrate to dryness, add 2ml of methanol to the residue to dissolve, and use it as the test solution; , add methanol to make a solution containing 0.4mg per ...
Embodiment 2
[0043] In this example, except that step (1) to step (6) in component identification and content determination are different from Example 1, other methods are the same.
[0044] Composition identification and content determination:
[0045] (1) Identification of capillary and Artemisia annua: Take 1g of this product, add 12ml of methanol, ultrasonically treat for 40 minutes, filter, evaporate the filtrate to dryness, add 2ml of methanol to the residue to dissolve, and use it as the test solution; , add methanol to make a solution containing 0.4mg per 1ml, as the artemisinin reference substance solution; take the artemisinin reference substance, add methanol to make a solution containing 0.2mg per 1ml, as the artemisinin reference substance solution; 5 μl of each of the above three solutions were spotted on the same silica gel G thin-layer plate, and 60-90°C petroleum ether: ethyl acetate: acetone = 8: 5: 3 by volume ratio was used as the developer, developed, and taken out. D...
Embodiment 3
[0054] In this example, except that step (1) to step (6) in component identification and content determination are different from Example 1, other methods are the same.
[0055] (1) The identification of capillary and Artemisia annua is as follows: take 1g of this product, add methanol 10ml, ultrasonically treat for 30 minutes, filter, evaporate the filtrate to dryness, add 2ml of methanol to dissolve the residue, and use it as the test solution; Add methanol to make a solution containing 0.4mg per 1ml, as the reference substance solution of artemisinin; take the reference substance of artemisinin, add methanol to make a solution containing 0.2mg per 1ml, as the solution of artemisinin reference substance; Take 5 μl of each of the above three solutions, spot them on the same silica gel G thin-layer plate, use 60-90°C petroleum ether: ethyl acetate: acetone = 7:4:2 by volume ratio as the developer, develop, and take out , dried, and inspected under a 365nm ultraviolet lamp.
