The antioxidative activity of the dried pericarp and seed of Japanese pepper was studied. The ethyl acetate extract from the pericarp and the methanol extract from the seed showed strong antioxidative activity against linoleic acid by the ferric thiocyanate and thiobarbituric acid (TBA) methods. Japanese pepper contained 3.9 and 2.9 mg/100 g of dry weight (dw) of tocopherols in the pericarp and seed, respectively, alpha-Toc in the former constituting 82% of total tocopherol and gamma-Toc in the latter constituting 96%. Arbutin and magnoflorine were isolated as antioxidants and their chemical structures determined by instrumental analyses. The contents of arbutin evaluated as the trifluoroacetate derivative by GC-MS were 35 and 3.0 mg/100 g of dw in the pericarp and seed, respectively. Magnoflorine was present only in the seed, and not in the pericarp. Both arbutin and magnoflorine exhibited antioxidative activity against linoleic acid and radical-scavenging activity against the DPPH radical.  相似文献

‘巨峰’葡萄主梢和副梢花器官与种子发育的研究     

胡建芳  张大鹏  贺海洋  松井弘之 《园艺学报》2001,28(3):262-264

 ‘巨峰’葡萄主梢花粉粒大于副梢, 花粉染色率与副梢差异不显著, 发芽率低于副梢, 但花粉发芽率不影响种子的形成。主梢小花雌蕊在减数分裂后形成的功能大孢子小于副梢。同时开花前主梢胚囊的发育状况优于副梢, 开花期正常胚囊率主梢也明显低于副梢。因此, 开花前后主梢异常胚囊的出现是导致受精发生障碍并使结籽率低下的原因。  相似文献

Real-space observation of helical spin order     

Uchida M  Onose Y  Matsui Y  Tokura Y 《Science (New York, N.Y.)》2006,311(5759):359-361

Helical spin order in magnetic materials has been investigated only in reciprocal space. We visualized the helical spin order and dynamics in a metal silicide in real space by means of Lorentz electron microscopy. The real space of the helical spin order proves to be much richer than that expected from the averaged structure; it exhibits a variety of magnetic defects similar to atomic dislocations in the crystal lattice. The application of magnetic fields allows us to directly observe the deformation processes of the helical spin order accompanied by nucleation, movement, and annihilation of the magnetic defects.  相似文献
