摘　　要：目的了解吉林地区山野菜中维生素C(VC)及黄酮的含量,便于山野菜的进一步开发和利用。方法VC含量的测定:2,4-二硝基苯肼法;黄酮含量的测定:紫外分光光度法。结果野菜中绿猴腿的VC含量最高,达到了94.5 mg/100 g,蒲公英最低,为28.2 mg/100 g,平均含量为48.5 mg/100 g,个别野菜的VC含量高于日常食用的蔬菜,但总体来说差别不大;从黄酮含量来看,山芹菜的最高,为3.615%,蒲公英的最低,为0.819%,平均含量为1.679%,山野菜黄酮类物质含量普遍高于日常食用的蔬菜。结论山野菜在VC含量上不具有优势,但它们却是获取黄酮类物质的良好来源,利用丰富的山野菜资源来提取制备黄酮类化合物有着很大的发展空间。Objective To understand the content of VC and flavonoids from potherb in Jilin region for further devel-opment and its application .Methods The 2 ,4-Dintrophenylhydrazine were employed to measure the content of VC;while ultraviolet spectrophotometryic were chosen for content of flavonoids .Results The highest content of VC is in Athyrium multidentatum （Doll） Ching,94.5 mg/100 g,while the lowest is in Taraxatum mongolicum Hand ,28.2 mg/100 g.The average content is 48.5mg/100g,only a few potherbs possess the higher VC content than other average vegetables,there is a little difference between them overall .The highest content of flavonoids is celery ,3.615%,while the lowest is Taraxatum mongolicum Hand ,0.819%,the average content is 1.679%.Flavonoids from potherb is high-er than other average vegetables generally .Conclusion Potherbs don＇t have advantages over average vegetables in VC content ,but they are good source for flavonoids .There are big space to extract flavonoids compound from potherb .
