New bergenin derivatives, bergecins A and B (1 and 2, resp.), have been isolated from the AcOEt-soluble fraction of Bergenia stracheyi, along with bergenin (3), and their structures were elucidated on the basis of (1) H- and (13) C-NMR spectra, and by COSY, HMQC, and HMBC experiments. Compound 2 showed potent inhibitory potential against the enzyme lipoxygenase, while 1 was moderately active. On the
从卑尔根Stracheyi的AcOEt可溶级分中分离出了新的卑尔根素衍生物A和B(分别为1和2)和卑尔根素(3),并根据(1)H阐明了它们的结构-和(13)C-NMR光谱,以及COSY,HMQC和HMBC实验。化合物2对脂氧合酶显示出强大的抑制潜力,而化合物1具有中等活性。另一方面,两种化合物在1,1-二苯基-2-吡啶并肼基(DPPH)清除试验中均显示出显着的抗氧化活性。
