[Direct identification of Perilla frutescens seeds from its confusable varieties by FTIR].
The IR of kernel and boil. cortex of perilla frutescens seeds and its confusable varieties were obtained directly, quickly and accurately by Fourier transform infrared spectroscopy. The results show that IR characteristics of different peaks and intensities of kernel and boil. cortex of Perilla frutescens(L). Britt. seeds and its confusable varieties, such as Mosla scabra (Thunb.) C. Y. Wu et H. W. Li, and M. Soochouensis Matsuda, and Mosla dianthera (Buch. Ham.) Maxim., are different. Obvious characteristics for its identification with different chemical compounds in FTIR were revealed, which can be used to identify Perilla frutescens(L.) Britt. seeds and its confusable varieties. Furthermore, the approach can be achieved quickly and accurately without extraction and separation of samples.
