Effect of extraction method on the concentrations of selected bioactive compounds in mandarin juice 总被引:2,自引:0,他引:2
A mandarin-type citrus fruit, ponkan (Citrus reticulata), was processed by in-line, chopper pulper, and hand-press extractions to investigate the effect of extraction method on the concentrations of bioactive compounds in processed juice. Concentrations of polymethoxylated flavones (tangeretin, nobiletin, and sinensetin) and beta-cryptoxanthin in juice, and inhibitory activities against arachidonate cyclooxygenase and lipoxygenases of the juice extract were analyzed. The juice processed by hand-press extraction contained the largest amounts of nobiletin (3.56 mg/100 mL), tangeretin (4.10 mg/100 mL), and sinensetin (0.13 mg/100 mL). Concentrations of beta-cryptoxanthin were 0.66, 0.59, 0.55, and 0.50 mg/100 mL in chopper pulper, in-line (5/64 in.), in-line (8/64 in.) and hand-press juices, respectively. Both extracts of in-line juices showed greater inhibitory activity toward platelet 12-lipoxygenase than the others. The inhibitory effect of hand-press juice extract on platelet cyclooxygenase activity was remarkable among juice extracts. All juice extracts effectively inhibited polymorphonuclear 5-lipoxygenase activity at nearly the same rate. 相似文献

Nineteen fig varieties and lines from Europe and Asia have been fingerprinted by ISSR, RAPD, and SSR markers, respectively,
using 13, 19, and 13 primer combinations. All primers produced 258 loci, with the highest number of loci (119) generated by
RAPD (R
p: 48.42). Clustering analysis was applied to the three marker datasets to elucidate the genetic structure and relationships
among these varieties. Mean genetic similarities were 0.787, 0.717, and 0.749, respectively, as determined using ISSR, RAPD,
and SSR. Each marker system produced incompletely separated clusters, although a weak binding group based on race type appeared
in the combined dataset. Comparisons of coefficients revealed no correlation between different similarity matrices; congruence
was observed between similarity matrices and co-phenetic matrices in all markers. Analysis of molecular variance (AMOVA) showed
that most of the total polymorphism was attributable to within-group variance (ISSRs + RAPDs, 97.41%; SSRs, 90.18%). These
results suggest that the genetic diversity of this fig population is low and that multiple marker utilization is critical
to estimate the relatedness of figs at the variety level. Additionally, it was presumed that ‘Houraihi’, the oldest variety
in Japan, was disseminated independently of other foreign varieties in the 17th century or before then. 相似文献
