Chemical component characterization and potential medicinal utilization of extracts and pyrolyzates from Jasminum nudiflorum Lindl. wood

Abstract

Utilization of lignocellulosic biomass is receiving increasing attention lately. In this study, Jasminum nudiflorum Lindl. (JNL) wood were extracted using methanol, ethanol, and benzene/ethanol (2:1, v:v) separately. Fourier transform-infrared spectroscopy (FTIR) and gas chromatography-mass spectroscopy (GC-MS) were used to study the chemical components of extracts. A thermogravimetric (TG) analyzer and pyrolysis (Py)-GC-MS investigated the characteristics of thermal loss law and pyrolyzates of JNL wood, respectively. The FTIR results showed that many functional groups were detected from the extracts of JNL wood, which were consistent with the chemical structures in the components detected by GC-MS. There were two obvious stages of thermal loss for removing moisture and decomposition of the organic constituents. The components of the extracts and pyrolyzates were esters, acids, aldehydes, alcohols, inositol, furfural, alkanes, phenols, ketones, antibiotics, saccharides, and glycosides. Among them, some components, such as ethyl iso-allocholate, scopoletin, isosorbide dinitrate, and idebenone, have high medicinal value. This study revealed the chemical component characterization and potential medicinal utilization of JNL wood. It provides the scientific basis for enhancing the utilization value of JNL wood.
