Quick Identification of Shuanghuanglian Oral Liquid and Yinhuang Oral Liquid by AOTF-near Infrared Spectroscopy Principal Component Analysis / 中国药房

ABSTRACT

OBJECTIVE:To apply AOTF-near infrared spectroscopy for quick identification of Shuanghuanglian oral liquid and Yinhuang oral liquid.METHODS:Yinhuang oral liquid and Shuanghuanglian oral liquid samples of different batches from different manufacturers were collected for collection of their near infrared spectra.The qualitative analysis models of the two kinds of oral liquid were established respectively using principal component analysis.Meanwhile,the established models were used to analyze and validate each other.RESULTS:The established qualitative analysis models of Shuanghuanglian oral liquid and Yinhuang oral liquid could be applied to validate and identify each other correctly.CONCLUSION:The method was proved to be a simple,rapid new analytical technique with low cost,and it can be used for a quick identification of Shuangh-uanglian oral liquid and Yinhuang oral liquid.
