[Objective] To comparatively analyze the major nutritional components of 8 wild vegetables from Guizhou Province like Cryptotaenia japonica Hassk., Geum japonicum Thunb., Mentha spicata Linn., Chenopodium album L., Aster sublatus Michx., Nasturtium officinale R.Br., Gnaphalium affine D. Don and Oenanthe javanica (Bl.) DC., so as to provide reference for the development and utilization of them. [Method] By employing conventional methods, the contents of basic nutrient components and mineral elements in 8 wild vegetables were determined. [Result] Contents of nutritional components in 8 kinds of wild vegetables varied with moisture content of 78.10%-93.40%, ash content of 8.74%-19.70%, fat content of 1.90%-0.90%, protein content of 0.31%-1.15%, crude fiber content of 10.20%-32.20%, polysaccharide content of 0.007%-0.054% and Vc content of 5.2-35.1 mg/kg. The content of K, Mg and Ca in Chenopodium album L. were the highest, being 8.6%, 2.20% and 3.23% respectively. The content of Na in Nasturtium officinale R.Br. was 6.15%, and that of Mn in Gnaphalium affine D. Don reached a peak (583.3 mg/kg). In addition, the content of Fe and Zn in Oenanthe javanica (Bl.) DC. were 0.24% and 131.8 mg/kg respectively, being the highest. [Conclusion] These 8 wild vegetables from Guizhou Province are rich in protein, fat, fiber, polysaccharide, vitamins and mineral elements, which are endowed with high exploring value.

The content of K, Mg and Ca in Chenopodium album L. were the highest, being 8.6%, 2.20% and 3.23% respectively. The content of Na in Nas Turtium officinale R.Br. was 6.15%, and that of Mn in Gnaphalium affine D. Don reached a peak (583.3 mg / kg). In addition, the content of Fe and Zn in Oenanthe javanica (Bl.) DC. % and 131.8 mg / kg respectively, being the highest.
