本文报道了从南五味子(Phenandra sphenanthera)根中分离得到的9个新木脂素(1-8,13)和5个已知木脂素(9-12,14),并测定了它们对2,2-二苯基-1-苦基-肼基(DPPH)的抑制作用。在所测试的这些木脂素中,化合物1、7、8和13表现出显著的抗氧化活性,其IC 50值分别为92、115、35和48 μ g/mL。评价了最具活性的化合物8的人红细胞(RBC)的抗氧化溶血活性,其与维生素C的活性相似。(C)2015 Elsevier B. V.版权所有。
Nine new lignans (1-8, 13) and five known ones (9-12, 14) have been isolated from the roots of Schisandra sphenanthera and were tested for their capacity to scavenge 2,2-diphenyl-1-Picryl-hydrazyl (DPPH). Of these lignans tested, compounds 1, 7, 8 and 13 exhibited noteworthy antioxidant activity with IC50 values of 92, 115,35 and 48 mu g/mL, respectively. The anti-oxidative haemolysis of human red blood cells (RBCs) activity of the most active compound 8, which is similar to that of vitamin C, was evaluated. (C) 2015 Elsevier B.V. All rights reserved.
