合水粉葛淀粉生产废渣水异黄酮成分比较分析

摘要

目的:了解合水粉葛淀粉生产废渣水中异黄酮含量和组成及其与葛粉和葛根原料的差别.方法:以葛根素为标准品,用高效液相色谱方法分析合水粉葛废渣、废水干物质与葛粉、葛根(分为根头、根皮和根芯三部分)中葛根素、总异黄酮含量和组成.结果:合水粉葛废渣、废水干物质中葛根素含量分别达到0.46%和0.34%,高于葛粉(0.21%)和葛芯(0.26%);其中葛渣中葛根素含量与根头相当(0.45%),总异黄酮含量则达到0.85%,超过根头(0.56%).另外葛渣和废水干物质中葛根素占总异黄酮含量的比例低于葛根,而且其它异黄酮组分也与葛根原料存在区别.结论:合水粉葛废渣和废水中含有值得进一步分析鉴定和分离纯化的异黄酮类化合物.%Objective:Understanding the isoflavonoid content and constituent in the waste residue and water from Heshui Pueraria thomsonii starch production and their differences from those in the starch and the root.Method :The isoflavonoid content and constituent in the waste residue and water,the starch and the different parts of the root (root head,root peel and root core included) were analyzed by HPLC with puerarin as the standard.Results: Puerarin contents in the waste residue and dried material of the waste water reached 0.46％ and 0.34％ respectively which were higher than in the starch (0.21％) and the root core (0.26％).The puerarin content (0.46％) and total isoflavonoid content (0.85％) in the residue were about equal to that(0.45％) and higher than that(0.56％) in the root, respectively.The ratios of puerarin/total isoflavonoid in the waste residue and water were lower than those in the root, and the other isoflavonoid constituents in the wastes were variable from in the root. Conclusion:It is worth to identified,separated and purified the isoflavonoids in the wastes.
