| Abstract: | Fourier transform infrared（FTIR） spectroscopy was used for obtaining vibrational spectra of the Tagetes erecta petal,Chrysanthemum indicum petal and Callostephus chinensis nees petal.Compared with the spectra of three chrysanthemum,the characteristic peaks of lutein ester were found.The content of lutein esters in the petal was studied by analysis of the relative absorption intensity.It could be used as a reference method for evaluation of the chrysanthemum.FTIR spectroscopy can provide content information about the lutein esters in the chrysanthemum.It is a physical method,and could provide the information of different kinds of chrysanthemum,while the advantage is convenient operation and nondestructive. |
