Embodiment 1
[0060] A kind of compound cortex cortex liquid, its raw material consists of:
[0061] Forsythia 80 parts by weight Cortex Phellodendri 40 parts by weight
[0062] Honeysuckle 40 parts by weight Dandelion 40 parts by weight
[0063] Centipede 2.4 parts by weight.
[0064] A preparation method of compound Phellodendron Phellodendron comprises the following steps:
[0065] (1) Weigh the five traditional Chinese medicines in the prescription according to the weight components, add water to decoct and extract three times, the first time is 1 hour, the second time is 45 minutes, and the third time is 30 minutes;
[0066] (2) Combine the decoctions, filter, and concentrate the filtrate to a clear paste with a relative density of 1.10-1.15 (measured at a temperature of 50°C);
[0067] (3) Add ethanol to make the ethanol content reach 70%, let it stand for 24 hours, filter, and concentrate the filtrate under reduced pressure until there is no ethanol, and obtain the clear liquid fo...

[0105] Experimental example 1: Research experiment on identification methods of various raw materials
[0106] Prepare compound Phellodendron phellodendron preparation according to the standard of compound phellodendron phellodendron preparation, test the identification method of various crude drugs wherein, experimental basis and result are as follows:
[0107] 1. Refer to the existing compound Phellodendron Phellodendron preparation standard to carry out identification test on forsythia. The results show that in the three batches of samples, spots of the same color appear on the positions corresponding to the chromatogram of the reference medicinal material, but the chromatographic spots of the reference medicinal material are not clear, and the chromatographic spots of the control medicinal material are not clear, and forsythia The glycoside reference substance was not developed. Therefore, it is not used as a part of the quality detection method of the compound Phellodendr...
