Comparison of mineral element content in nine wild vegetables from Qinling Mountains

Contents of Zn,Cu,Mn,Fe,Ca,Mg,N,P and K in Cardamine macrophylla var.macrophylla Willd.,Houttuynia cordata Thunb.,Pteridium aquilinum var.latiusculum(Desv.) Underw.ex Heller,Aralia chinensis L.,Osmunda japonica Thunb.,Vitex trifolia L.,Chenopodium album L.,Lycium chinense Miller and Cichorium intybus L.from Qinling Mountains were determined,and compared to average contents of those mineral elements in cultivation foliage vegetables.The results show that contents of Zn,Cu,Mn,Fe,Ca,Mg,N,P and K in nine wild vegetables are 2.90-14.20,0.5-3.6,2.7-14.3,4.5-50.6,141.9-4 646.0,106.3-643.9,2 029.8-8 583.5,295.3-1 136.0 and 3 870.0-14 011.9 μg·g-1,respectively.In which,Fe content in C.intybus,Ca content in V.trifolia,Mg and K contents in C.album,Zn and Mn contents in A.chinensis and Cu,N and P contents in O.japonica all are the highest.Average contents of Ca,N,Fe and K in nine wild vegetables from Qinling Mountains all have very obvious difference with those in cultivation foliage vegetables,but differences in average contents of Cu,Mg and P among them are relatively small.
