Study on Infrared Spectrum Fingerprint of Apocynumvenetum L. in Xinjiang Based on Double Index Analysis
Apocynum venetum L. was a commonly used medicinal material in Xinjiang, mainly used for hepatic yang vertigo, palpitation and insomnia, oedema and oliourine, and it also had a good therapeutic effect on hypertension and depression. In order to ensure safety and stability of clinical medication, four traditional identification methods and modern chromatographic and spectral techniques were commonly used to identify the quality differences of Chinese medicinal materials. In this study, 17 batches of A. venetum collected from different regions in Xinjiang were analyzed by Fourier transform infrared spectroscopy (FTIR ). The range of infrared spectrum was 4 000~400 cm-1, the range of secondary derivative spectra was 1 800~600 cm-1. After obtaining these fingerprints, the correlation coefficients were calculated by using the fingerprint spectrum (1 800~400 cm-1) with dense spectral bands. Then, the infrared fingerprints of A. venetum from different habitats were classified and compared by combining the infrared spectral absorption peak system clustering, the common peak rate and the variation peak rate double index sequence analysis. The results showed that the infrared spectra of A. venetum from different regions in Xinjiang were similar in shape and position of peaks, and all of them had absorption in wavenumber of 3 336, 2 920, 1 443, 1 375, 1 247, 1 103, 1 070, 833 and 601 cm-1. There were characteristic and strong peaks at 1 103, 1 070 and 1 656~1 609 cm-1. And the C
