In this paper， ginger for the materials to ethanol as an extraction solvent to extract the flavonoids， using visible light spectrophotometry at a wavelength of 510 nm Department Determination of total flavonoids in Test the main consideration of ethanol concentration， solid-liquid ratio， extraction time and extraction temperature of the four factors on the extraction rate of flavonoids， which have taken every single factor of five different Through single-factor experiments extraction parameters on the initial screening， through the orthogonal test to determine the relationship between primary and secondary parameters in order to get the best extraction Test to determine the optimum extraction conditions for 80% of the ethanol solution as the solvent， the solid-liquid ratio of 1:25， returning at 70 ℃ under the 5h， the highest rate of Factors identified for the primary and secondary extraction temperature， extraction time， ethanol concentration， solid-liquid Pilot experiments and the use of single-factor orthogonal experiment to extract the total flavonoids ginger to ginger flavonoids find the best extraction method， a reasonable choice for the extraction of flavonoids ginger provide a reference for the development of ginger products lay the foundation for
不知道你问的是投稿格式还是毕业论文用的，如果是投稿的，各个杂志的要求在细节上不一样，但结构大同小异。基本上包括：1。标题（Title）2。作者（Author(s)）3。通讯作者的联系方式(Contact information)4。摘要(abstract)5。背景介绍（Background or introduction）6。实验材料与方法（Materials and Methods）7。结果（result）8。讨论（discussion）9。致谢(acknowledgment)10。参考文献 （references）毕业论文参考这样的格式也绝对没有问题，不过不用把其他作者写进去。
