Abstract

Two new phenylpropanoid glycosides, caerulescenoside ( 1), and 3'-methyl crenatoside ( 2), as well as five known phenylpropanoid glycosides [acteoside ( 3), isoacteoside ( 4), campneoside II ( 5), crenatoside ( 6), and desrhamnosyl acteoside ( 7)] were isolated from the whole plant of Orobanche caerulescens. The antioxidative effects of compounds 1 - 7 on human low-density lipoprotein were evaluated. All these compounds suppress concentration-dependently conjugated diene formation with IC (50) values of 1.25 +/- 0.06, 2.97 +/- 0.31, 0.31 +/- 0.01, 1.01 +/- 0.05, 1.15 +/- 0.04, 1.69 +/- 0.15, and 0.64 +/- 0.03 microM, respectively. Comparison of their antioxidative activities with that of resveratrol (IC (50) : 6.75 +/- 1.05 microM), a natural phenolic antioxidant isolated from grape, demonstrated that the prolonged effect on lag-time and the damping effect on oxidative rate by compounds 1 - 7 were all more potent.
