A New Monoterpene-Coumarin and a New Monoterpene-Chromone from Gerbera delavayi.

Phytochemical investigation of the whole plants of Gerbera delavayi (Compositae) led to the isolation and identification of 15 compounds, including the new monoterpene-coumarin and the new monoterpene-chromone . Their structures were determined on the basis of spectroscopic analyses including 1D- and 2D-NMR experiments and comparison with spectroscopic data of the literature. [ABSTRACT FROM AUTHOR]
