| Abstract: | Differences of different parts of Trichosanthis Fructus have been studied by using Fourier transform infrared(FTIR) spectroscopy and the second derivative spectra.IR absorption indicates the existence of saccharides and glucosides in all parts of Trichosanthis Fructus.It also can be identified that there are flavone and ester in Trichosanthis Semen and Trichosanthis Pericarpium.However,the pulp of Trichosanthis Fructus and Trichosanthis Pericarpium contains quantities of starch.The second derivative spectra shows that at the wave number from 1800 cm-1 to 700 cm-1,the peak shape of Trichosanthis Semen is the simplest,following by the the pulp of Trichosanthis Fructus.The peak shape and strength of Trichosanthis Fructus and Trichosanthis Pericarpium are similar,while Trichosanthis Pericarpium reveals more fingerprint peaks.The infrared spectra can provide useful information for the chemical study and the clinical drug usage of the Trichosanthis Fructus. |
