| 1 | Profiles of phenolics,carotenoids and antioxidative capacities of thermal processed white,yellow,orange and purple sweet potatoes grown in Guilin,China显示文摘The objectives of this study were to systematically compare phenolic profiles,carotenoids profiles and antioxidant activities of raw and cooked sweet potatoes of five varieties(white,yellow,orange,light purple and deep purple).Total phenolic content(TPC),monomeric anthocyanin content(MAC),total carotenoid content(TCC),2-diohenyl-1-picryhydrazyl(DPPH)free radical scavenging capacities and ferric reducing antioxidant powder(FRAP)were determined by colorimetric methods.Higher anthocyanin contents and antioxidant capacities were detected in purple sweet potato species,while higher carotenoid contents were detected in yellow and orange sweet potato.All cooked sweet potato exhibited significantly(p<0.05)lower TPC,MAC,TCC,DPPH and FRAP values as compared to the respective raw samples.Under the same cooking time,steaming was good for the retention of TPC,roasting was good for keeping anthocyanins,and boiling was beneficial to preserve carotenoids. | Yayuan Tang Weixi Cai Baojun Xu | 2015 | Food Science and Human Wellness2015，4，3： | 3 |
| 2 | Study on the interaction between β-carotene and gut microflora using an in vitro fermentation model显示文摘β-Carotene,a typical non-oxygenated carotenoid,is the most efficient source of retinol(VA).The low bio-availability ofβ-carotene lead to large accumulation in colon;however,the relationship betweenβ-carotene and gut microflora remains unclear.This study intends to explore the interaction betweenβ-carotene and gut microflora using an in vitro fermentation model.After 24 h fermentation,the degradation rate ofβ-carotene was(64.28±6.23)%,which was 1.46 times that of the group without gut microflora.Meanwhile,the production of VA was nearly 2 times that of the group without gut microflora,indicating that the gut microflora can metabolizeβ-carotene into VA.β-Carotene also influences the production of short-chain fatty acids(SCFAs),the production of total SCFAs in 0.5 mg/mLβ-carotene(BCM)group was(44.00±1.16)mmol/L,which was 2.26 times that of the blank control(BLK)group.Among them,the production of acetic acid in BCM group was(19.06±0.82)mmol/L,which was 2.64 time that of the BLK group.Furthermore,β-carotene significantly affected the structure and composition of gut microflora,increasing the abundance of Roseburia,Parasutterella and Lachnospiraceae,and decreasing the abundance of Dialister,Collinsella and Enterobacter(P<0.05).This study provides a new way to understand howβ-carotene works in human body with gut microflora. | Zhixian Li Zhuqing Dai Enjuan Shi Peng Wan Guijie Chen Zhongyuan Zhang Yayuan Xu Ruichang Gao Xiaoxiong Zeng Dajing Li | 2023 | Food Science and Human Wellness2023，12，4： | 0 |
| 3 | Lutein-stevioside nanoparticle attenuates H_(2)O_(2)-induced oxidative damage in ARPE cells显示文摘In order to improve the bioavailability of lutein(LUT),a novel lutein-stevio side nanoparticle(LUT-STE)were prepared previously,but the information about LUT-STE on protecting of eye health was limited.This study investigated the effect of LUT-STE on antioxidant activity of H_(2)O_(2)-induced human retinal pigment epithelial(ARPE)cells.LUT and LUT-STE(final concentration of 5μg/mL)significantly enhanced cell viability from(74.84±5.10)%to(81.92±10.01)%(LUT)and(89.33±4.34)%(LUT-STE),and inhibited the cell apoptosis(P<0.05).After pretreatment with LUT-STE in ARPE cells,the levels of superoxide dismutase(SOD),catalase(CAT)and glutathion peroxidase(GSH-Px)in ARPE cells were significantly increased(P<0.05),the contents of reactive oxygen species(ROS)and malondialdehyde(MDA)were decreased.In addition,the vascular endothelial growth factor(VEGF)levels were inhibited by 13.61%and 17.39%,respectively,pretreatment with LUT and LUT-STE.Western blotting results showed that the pretreatment with LUT-STE inhibited the expression of caspase-9 and caspase-3 and up-regulated Bcl-2/Bax pathway to inhibit H_(2)O_(2)-induced apoptosis.In summary,the novel delivery LUT-STE had more pronounced inhibitory effect on H_(2)O_(2)-induced damage in human ARPE cells. | Zhuqing Dai Meimei Nie Ye Chen Jiangfeng Song Yayuan Xu Zhongyuan Zhang Guodong Zhang Shumo Yan Xing Zhang Dajing Li | 2024 | Food Science and Human Wellness2024，13，3： | 0 |
