摘　　要：在超声波辐射下用NaOCl水溶液氧化玉米秆粉末(CSP),经过滤分离得到滤液和滤渣,依次用CS2、CH3OH和CH3COCH3萃取滤渣,得到萃取物E1～E3,用GC/MS分析E1～E3。结果表明,在二硫化碳萃取物中共检测出17种有机化合物,且大部分为有长碳链结构的有机物;在甲醇萃取物中只检测出1种长链脂肪酸酯;在丙酮萃取物中共检测出40种有机物,包括多种芳香族化合物及少量正构烷烃。The corn stalk powder （CSP） was oxidized with NaClO aqueous solution under the ultrasonic irradiation, and extracted by CS2, methanol and acetone. The products extracted in all levels from the oxidized CSP were analyzed with GC/MS. 17 kinds of organic compounds are identified in the CS2 extracts, most of which are structured with long carbon chain, while only one long chain fatty acid ester is detected in methanol extracts; 40 kinds of organic matter are identified in acetone extracts, including a variety of aromatic compounds and a small amount of n-alkanes.
