摘要
黄酮类化合物广泛存在于植物界,是许多中草药的有效成分。在自然界中最常见的是黄酮和黄酮醇,此外,还有双氢黄醇、异黄酮、双黄酮、黄烷醇、查尔酮、橙酮及花色苷等。由于类黄酮具有很强的抗氧化和消除自由基的作用,备受国内外研究者的青睐,成为研究的热点。黄酮类化合物有着重要的医用价值,主要体现在:抗炎症、抗过敏;抑制细菌、抑制病毒;防治肝病、防治血管疾病;抗肿瘤、抗化学毒物等。本文从节约资源、提高黄酮得率、实验操作性强等方面分析,选取紫薯茎叶为实验材料,并结合国内外大量研究理论成果,论述了黄酮类化合物的提取方法,将这些方法的优缺点进行了总结,同时,详细的阐述了黄酮类化合物的功能性研究进展,希望对黄酮的研究者起到借鉴、提供参考的价值。
Flavonoids are widely found in the plant community,which are the active ingredient of many Chinese herbal medicines.In nature,the most common flavonoids are flavones and flavonols.In addition,there are double hydrogen flavonols,isoflavone,double flavone,flavanone alcohol,chalcones,aurones and anthocyanin,etc.Because of its strong antioxidant and free radical elimination effect,it has been favored by researchers at home and abroad,and has become a hot research topic.Flavonoids have important medical values,mainly in anti-inflammatory,anti allergy,inhibition of bacteria and virus,prevention and treatment of liver disease,prevention and treatment of vascular disease,anti tumor and anti chemical poison,etc.This paper selected purple sweet potato stems and leaves as experimental materials,and combined with a large number of domestic and foreign research achievements in theory to discuss the extraction methods of flavonoids from the aspects of conservation of resources,improvement of flavonoids yield and experimental operational.The advantages and disadvantages of these methods were summarized and the research advances in function of flavonoids were detailed described,in order to provide references for the researchers.
