【導(dǎo)讀】DPPH自由基清除能力、ABTS+·清除能力測(cè)定、清除超氧離子自由基、脂質(zhì)過氧化抑制作用的測(cè)定、考資料和書籍的情況下,仔細(xì)分析并且找到解決之道。在確定實(shí)驗(yàn)方案不能取得理想結(jié)果的情況下,積極調(diào)整實(shí)驗(yàn)方案,確定最佳試驗(yàn)條件。在開始實(shí)驗(yàn)設(shè)計(jì)之后,每天要首先作好當(dāng)天的內(nèi)容安排,劃期內(nèi)圓滿地完成整個(gè)畢業(yè)課程實(shí)驗(yàn)。最后要按畢業(yè)設(shè)計(jì)的要求總結(jié)實(shí)驗(yàn)成果,撰寫畢業(yè)論文,完。成畢業(yè)論文答辯。工作及取得的研究成果;得其他教育機(jī)構(gòu)的學(xué)位而使用過的材料;

  

【正文】 清除能力較好, 2 mg/mL 時(shí)清除率可達(dá) 50%左右;相較之下,對(duì) DPPH 清除率稍弱,在濃度為 10 mg/mL 時(shí)為 80%左右;但是三個(gè)錐栗淀粉樣品對(duì)脂質(zhì)過氧化抑制率,超氧陰離子自由基清除率及亞硝酸鹽的清除率效果較差,需加大濃度才能達(dá)到 50%以上的清除率。 化學(xué)化工學(xué)院 20xx 屆本科畢業(yè)論文 17 參考文獻(xiàn) [1] Englyst HN, Kingman SM, Cummings JH.
