The TG curve showed that the largest mass loss occurred from 240 to 350 ℃, within that temperature range, the sample lost nearly all its mass. The DTA curve illustrated that melting temperature was 107.63 ℃, and pyrolysis temperature was 325.29 ℃. The main pyrolysis products were benzenoid and heterocyclic compounds. The number of pyrolysis products increased with the rise of temperature. This study provided a reference for investigating the transformation behavior of phenylethyl β-D-glucopyranoside during cigarette combustion.
