摘要

Bidimensional NMR analysis may be a useful tool to resolve the structure of chemical compounds also in mixture. This letter would demonstrate how these techniques could be applied e.g. to the reported case on identification of benzophenone glycoside from Psidium guajava. A tentative structure for the secondary component, not yet described, was possibly proposed on the basis of observation and critic review of available 1D and 2D NMR spectra.
