Study on the Interaction Between Tangerine Peel and Beer by Absorption Spectrum

This paper presents a new method to study the interaction between tangerine peel and beer by absorption spectrum.The author explores the change laws and the differences of the absorbance on some wave band from the absorption spectrums of tangerine peel and the mixture of tangerine peel and beer. The results show that there is an obvious difference around 323 nm though the absorbance values of the two samples are almost similar in the most bands. The absorbance value of the mixture is obviously greater than that of tangerine peel at 276 nm in the spectrums, and there is a shift of the peak position in the absorption spectrum of the mixture, which shows the differences of the absorbance values and the peak positions of the two samples. Through comparing the characteristics of the two samples' absorption spectrums, a new method for researching new pharmacological action of tangerine peel is presented in this paper. The result indicates that the technology of spectrum analysis will play an important role in the research and development of Chinese herbal pharmacology and new pharmacology.
