Abstract
After ⁶⁰Co γ-ray irradiation pretreatment of Chinese silvergrass, a variety of products were identified by ion chromatography (IC) and gas chromatography–mass spectrometry (GC-MS). According to IC analysis, the degradation products included arabinose, galactose, glucose, xylose, D-galacturonic acid and D-glucuronic acid. The GC-MS analysis identified 22 carboxylic acids, 19 aromatic compounds and 3 furan compounds. The irradiation degradation mechanism was also discussed.
