Isolation and Identification of a New Glycoside in Tobacco and Analysis of its Pyrolytic Products

    Abstract
  • A new glycoside,(E)-N-(4-hydroxy-3-methoxy)-phenethyl-3-(3-methoxy-4-O-β-D-glucopyranosyloxy) phenylacrylamide(Ⅰ), was isolated from leaves of flue-cured tobacco cv."Hongda" through extraction with 95% ethanol,preparation at normal and high pressure and separation with chromatography. The molecular structure of compound(Ⅰ) was identified with HRESI-MS and NMR. Compound(Ⅰ) was pyrolyzed in He atmosphere and its pyrolytic products were analyzed by GC/MS. The results showed that the separated product was compound (Ⅰ),and its major pyrolytic products were 4-vinylguaiacol,guaiacol,vanillin,p-cresol,2, 3-dihydrobenzofuran, 4-allylphenol, and m-ethylphenol.
