Abstract: Total ash, water-insoluble ash and acid-insoluble ash in forty-one paper-process reconstituted tobacco (RT) products were determined and analyzed. The results showed that the means of total ash, water-insoluble ash and acid-insoluble ash contents of the domestic RT products (17.33%, 12.46% and 0.55%, respectively) were lower than those of the imported (19.18%, 14.34% and 0.59%, respectively), and there were extremely significant differences at the 0.01 significance level. Cluster analysis results showed forty-one paper-process RT products were divided into three groups on the basic of total ash, water-insoluble ash and acid-insoluble ash contents factors. Correlation analysis revealed that there was extremely significant correlation between total ash and water insoluble ash in RT products, and the relationship was described by the linear regression equation: y=9.951e0.051x (x for water insoluble ash and y for total ash, respectively).
