Functional group Cinnamomum porrectum wood extractives by Fourier Transform Infrared

Abstract

Extractive from Cinnamomum porrectum wood was obtained using Soxhlet extraction with five different types of solvent, which are distilled water, ethanol, acetone, chloroform, and benzene. From the result, ethanol extraction shows the highest extractives yield which are 2.692%, following by acetone (1.461%), chloroform (0.940%), benzene (0.109%) and distilled water (0.005%). Extractive make a major contribution to the characteristics of wood or non-wood species. These extractives are low-molecular weight compounds, and the different classes of extractives have different chemical behaviours. In this study, the FT-IR was used to analyse the extractive of the Cinnamomum porrectum wood with ethanol, distilled water, chloroform, benzene and acetone. From the result shows that, the analysis revealed 5 different types of functional group which are O-H stretching in presence of phenolic group, C-H stretching in presence of alkane group, C-F stretching in presence of alkyl halide group; C-O stretching in presence of aldehyde group and C=C stretching in presence of alkene group.
