Abstract
A novel terpenoid, cydonioside A (1), was isolated from the fruits of Cydonia vulgaris Pers. Its structure and relative configuration were elucidated on the basis of in‐depth spectroscopic analyses, including 2D‐NMR experiments as well as MM+ calculations. Compound 1 was assayed for its radical‐scavenging activity towards the DPPH radical and the superoxide radical anion (O${{_{2}^{{^\cdot} -}}}$), as well as for its overall antioxidant activity, as assessed by the formation of a phosphomolybdenum complex.
