Abstract:
ObjectiveTo identify the chemical composition of stem, leaf and peel ofCynanchumchinese R.Br..MethodsFourier IR spectra, the second derivative spectrum and two-dimensional correlation spectroscopy were adopted to identify IR of different parts ofCynanchumchinese R.Br..ResultsIt was found that the IR spectra of the leaf was similar to that of the peel but was different from the stem. What’s more, in the second derivative spectra of the leaf, it showed that the absorption peak was strong at the position of 1 543 cm-1, 1 515 cm-1, 1 499 cm-1 and 1 467 cm-1, respectively and there existed carbonyl absorption peak at 1 738 cm-1 and 1 659 cm-1 in addition. Therefore, it was inferred that flavonoids were the major components while less in the stem and peel.ConclusionsThe differences of the three parts aboutCynanchumchinese R.Br. were studied through IR spectrum macroscopically, which provided reference for exploring the constituents and clinical medication.
