ABSTRACT
<p><b>OBJECTIVE</b>To propose an algorithm of the similarity between UV-spectra for controlling the quality of Chinese medical injection.</p><p><b>METHOD</b>The similarity is calculated base on the data of two UV-spectrum curves, thus the sample quality is evaluated according to the average value of the similarity of the UV-spectra between sample with each of standard samples; the proposed algorithm of the similarity is compared with cosine of vectorial angle and relative coefficient; the proposed method for quality evaluation of traditional Chinese injection is discussed with the method according to the chromatographic fingerprint similarity.</p><p><b>RESULT</b>The calculated similarity with the proposed method can be sensitive to show the difference between UV-spectra. This proposed method for quality evaluation was applied for assessing quality of 14 batches of Xiangdan injection and the results well coincident with sample quality.</p><p><b>CONCLUSION</b>The proposed method can be used to evaluate the quality of the Chinese medical injection according to the similarity of two UV-spectrum curves.</p>
