We classified vegetables and fruits into four groups according to the color of their edible parts(e.g., green, orange/yellow, red/purple and white). Vegetable and fruit intake level was classified by sex-specific tertile of the control group. Logistic regression models were used for estimating the odds ratios(OR) and their 95% confidence intervals(CI).RESULTS High total intake of vegetables and fruits was strongly associated with a reduced risk of colorectal cancer in women(OR = 0.32, 95%CI: 0.21-0.48 for highest vs lowest tertile) and a similar inverse association was observed for men(OR = 0.60, 95%CI: 0.45-0.79). In the analysis of color groups, adjusted ORs(95%CI) comparing the highest to the lowest of the vegetables and fruits intake were 0.49(0.36-0.65) for green, and 0.47(0.35-0.63) for white vegetables and fruits in men. An inverse association was also found in women for green, red/purple and white vegetables and fruits. However, in men, orange/yellow vegetables and fruits(citrus fruits, carrot, pumpkin, peach, persimmon, ginger) intake was linked to an increased risk of colorectal cancer(OR = 1.61, 95%CI: 1.22-2.12).CONCLUSION Vegetables and fruits intake from various color groups may protect against colorectal cancer.展开更多

Analysis of the single nucleotide polyTnorphisms from bulked F2 pools identified the causative variant occurring in Csa4G126690. Csa4G126690 shows high homol- ogy to Arobidopsis 5EPALLATA2 （SEP2） thus being desig- nated CsSEP2. The causative variant was located on the splicing site of CsSEP2, resulting in the skipping of exon 6 and abolishment of the transcriptional activity. Our data suggest that CsSEP2 is involved in the floral organ and fruits development by conferring transcriptional activity.展开更多

The HPLC separation was performed using a Shim-pack VP-ODS C18 column （250 mm ~ 4.6 mm i.d., 5 ~tm） with the isocratic mobile phase consisting of tetrahydrofuran/ acetonitrile/0.05% phosphoric acid solution （20：3：77, v/v/v）, and the flow rate was set at 1.0 mL/min. UV detection was carried out at a wavelength of 360 nrn and the whole analysis took 25 min. The method was linear in the range of 4.12-206.00 μg/mL for vitexin-2＂-O-glucoside, 4.05-202.50 μg/mL for vitexin-2＂-O- rhanmoside, 1.64-82.00 pμg/mL for rutin, 1.74-87.00 gg/mL for vitexin, and 1.41-70.60 p.g/mL for hyperoside with the correlation coefficient for each analyte more than 0.998. The limit of detection （LOD） and limit of quantitation （LOQ） were 0.6 and 2 ng for vitexin-2＂-O-glucoside, 0.6 and 2 ng for vitexin-2＂-O-rhamnoside, 0.3 and 1 ng for rutin, 1 and 3 ng for vitexin, and 0.5 and 2 ng for hyperoside, respectively. Intra- and inter-day precision and accuracy （RSD） were less than 3%. The developed HPLC method was successfully applied to the analysis of five flavonoids in hawthorn leaves, hawthorn fruits, and the preparations containing hawthorn leaves or fruits.展开更多
