Abstract
Eucommia ulmoides leaves were phytochemically and biologically studied for their antioxidant properties. Two new geniposides (ulmoside C and ulmoside D) and one known compound (10-O-acetylgeniposidic acid) were isolated from E. ulmoides. Evaluation of their free-radical scavenging activity with respect to DPPH, ABTS, and superoxide anions showed that ulmosides C and D possess outstanding properties with IC50 values of 6.5 ± 0.20 and 7.5 ± 0.01 μM (DPPH), 2.1 ± 0.007 and 3.5 ± 0.31 μM (ABTS), and 8.1 μ0.17 and 10 ± 0.09 μM (superoxide anion), respectively.
