Abstract

Abstract: Nopol was ozonized in methanol and ethanol respectively, followed by reductive hydrolyzation and GC MS analysis.The MS data was analyzed, and structures of6 main products have been identified, namely:cis-2, 2-dimethyl 3-(β-hydroxypropionyl) cyclobutaneethanal, 3 hydroxy cis-2, 2-dimethyl 3-(β-hydroxypropionyl) cyclobutaneethanal, 1 hydroxy cis-2, 2-dimethyl 3-(β-hydroxypropionyl) cyclobutaneethanal, cis cis-2, 2-dimethyl 3-(β-hydroxypropionyl) cyclobutaneacetaldehyde dimethyl acetal, cis-2, 2-dimethyl 3-(β-hydroxypropionyl) cyclobutaneacetaldehyde diethyl acetal and 2, 2-dimethyl 3-(β-hydroxypropionyl) butanone.The results showed:1)The 6 main products are all four member ring compounds produced through the cleavage of double bond of nopol;2)Accompany with oxidations of the double bond and tertiary hydrogen in the ozonization, there are other reactions at more in depth levels.

Key words: nopol, ozonization, GC-MS analysis, four-member-ring compound
