Abstract

Volatile compounds in different tissues of Polygonum minus (leaves, stems and roots) were isolated using the Solid Phase Microextraction (SPME) technique, and analysed by two-dimensional gas chromatography, GC x GC-TOF MS in the hope of identifying more minor components in the tissues. In total, 55 compounds were identified in the samples, of which 32 were terpene compounds. The overall content of each compound was different in the leaves, stems and roots. The aerial parts (leaves and stems) were relatively rich in terpenoids, whereas the roots were relatively rich in organic acids. The spectral studies of the tissues were done using Fourier transform infrared spectroscopy (FTIR) to further correlate with its chemical constituents of the samples. The principal component analysis (PCA) was used for the discrimination of the different tissues by using their marker bands. With this technique, the different tissues could be well distinguished by this rapid method with the exception of the chromatographic technique and could be further developed as a routine test in food industry.
