Examples
Embodiment 1
[0056] Example 1 Changes in the isosbestic point and area under the curve of Qingkailing injection.
[0057] Take 10ml of Qingkailing injection (batch number 1003272) purchased in the market, take a sample of 1.0ml for later use (recorded as standard sample Q0), add the remaining injection into a 15ml capped centrifuge tube, close the cap tightly and place it in a 60°C water bath for constant temperature . After 1, 2, 3, 4, and 8 weeks, 1.0 ml samples were taken at fixed time points (the samples were respectively marked as Q1, Q2, Q3, Q4, and Q8). After the sample is taken, it is sealed and stored at -20°C. After the sample is taken, the absorption spectrum detection is performed, and the fingerprint detection is performed in parallel to verify from the side (reference literature: Wang Zhihong, Zhao Xuyuan, Yao Jincheng. Qingkailing injection fingerprint HPLC study of the spectrum. Chinese Journal of Traditional Chinese Medicine 2008; 26:868-70).

Embodiment 2
[0067] Example 2 Changes in isosbestic point and area under the curve of Shuanghuanglian injection.
[0068]Take 10ml of Shuanghuanglian injection (batch number 20100324) purchased in the market, sample 1.0ml for later use (denoted as standard sample S0), add the remaining injection into a 15ml capped centrifuge tube, close the cap tightly and place it in a 60°C water bath for constant temperature. After 1, 2, 3, 4, and 8 weeks, 1.0 ml samples were taken at fixed time points (the samples were respectively marked as S1, S2, S3, S4, and S8). After the sample is taken, it is sealed and stored at -20°C. After the sample is taken, the absorption spectrum is detected, and the fingerprint is detected in parallel to verify from the side (reference literature: Li Fang, Jiang Wenhong, Liu Lijuan, Zhong Zhaoqing. Injection Establishment of fingerprints of Shuanghuanglian (lyophilized) and its application in quality control. Chinese Patent Medicine 2007;29:1196-8).

Embodiment 3
[0080] Example 3 Changes in the isosbestic point and area under the curve of Danshen injection.
[0081] Take 10ml of Danshen injection (batch number 1005104) purchased in the market, sample 1.0ml for later use (denoted as standard sample D0), add the remaining injection into a 15ml capped centrifuge tube, close the cap tightly and place it in a water bath at 60°C for constant temperature. After 1, 2, 3, 4, and 8 weeks, 1.0 ml samples were taken at fixed time points (the samples were respectively marked as D1, D2, D3, D4, and D8). After the sample is taken, it is sealed and stored at -20°C. After the sample is taken, the absorption spectrum detection is carried out, and the fingerprint detection is performed in parallel to verify from the side (reference literature: Xu Man, Liu Aihua, Cui Yajun, Zhang Jinlan, Guo Dean.
