Among the vegetables, green chili showed the highest total oxygen radical absorbance capacity （ORACFL） and lipophilic ORAC （L-ORACFL）; whereas, bean showed highest hydrophilic ORAC （H-ORACFL） content. The H-ORACFL of vegetable samples varied between 2.26 to 23.08 ~tmol of Trolox equivalent （TE）/g of fresh weight （FW） and L-ORACFL content widely varied from 0.20 （sweet pumpkin） to 16.95 （green chili）. The range of H-ORACFL values of fruits showed large variation （0.45-178 Ixmol of TE/g FW）. All four different types of tea showed high H-ORACFL （1,295.84-2,709.11 lamol of TE/g）, in contrast to negligible amount of L-ORACFL. In legumes, H-ORACFL content ranged from 16.22 to 140.54; whereas, L-ORACFL ranged from 4.43 to 25.78. Porso millets showed higher L-ORACFL value （19.4） as compared to H-ORACFL （0.8）. In case of spices, L-ORACFL content varied from 29.75 ± 0.00 to 1,575.24 ± 39.63, which is considerably higher as compared to H-ORACFL （61.68 ± 1.71 to 272.82± 1.05） content. Comparatively, spices showed much higher H-ORACFL values as compared to fruits analyzed. In case of selective vegetables, fruits and tea samples, the total phenol content was highly correlated with the H-ORACFL content.展开更多

An approach based on both panel data and multi-inputs/outputs is considered comprehensively, and aims at measuring the operating efficiencies of 10 leading container ports in China from 2001 to 2006 by applying this new systematic influence factor of total factor productivity change is the calculation method. The results illustrate that the main technology change, and the container transportation of these 10 ports is on the healthy development status and will recover and grow reposefully in the following years展开更多
