摘要：[Objectives]The quality of Lycium ruthenicum Murr.from different producing areas was studied.[Methods]The content of proanthocyanidins(UV spectrophotometry),water-soluble vitamins(VB 2,VB 6,VB 12,Vc,niacinamide,and folic acid)),fat-soluble vitamins(VD,and VK 1)(high performance liquid chromatography),and trace elements Cu,Zn,and Fe(flame atomic absorption method)in L.ruthenicum from Ejin Banner of Inner Mongolia,Nuomuhong of Qinghai and Korla of Xinjiang were measured.[Results]The content of proanthocyanidins,VB 2,nicotinamide and VB 12 in L.ruthenicum from Ejin Banner was higher,and the content of Vc,VB 6,Cu,Zn,VD and VK 1 in L.ruthenicum from Nuomuhong was higher,while the content of folic acid and Fe in L.ruthenicum from Korla was higher.The proanthocyanidin content of L.ruthenicum from Ejin Banner was the highest,so it is an ideal plant for extracting proanthocyanidins.[Conclusions]This study provides a theoretical basis for the research,development and utilization of L.ruthenicum from Nuomuhong,Ejin Banner and Korla.
