Using the ethanol extract, Achyranthis Radix, various chemical characteristics were investigated. The nutritional compositions of the Achyranthis Radix extract were as follows:moisture 42.3%, crude protein 101.1%, crude fat 2.07%, ash 8.94%, and carbohydrate 36.5%. Among the free sugars, the maximum lactose concentration in the Achyrenthis Radix extract was obtained at 0.0526 ㎎% and fructose, maltose, arabinose, and glucose were followed: 0.3654 ㎎%, 0.1160 ㎎%, 0.0365 ㎎% and 0.027 ㎎%, respectively. The total amino acid concentration of the Achyrsnthis Radix extract was 8908.3 ㎎% and concentrations of lysine, aspartic acid, glutamic acid, and arginine were 989.1 ㎎%, 954.4 ㎎%, 841.4 ㎎% and 763.2 ㎎%, respectively. Among various long chain fatty acids, the maximum concentrations of palmitic acid and linoleic acid were obtained at 47.8% and 31.058%, respectively. However, in the case of organic acid, only the oxalic acid and malic acid were determined. The potassium concentration in the Achyranthis Radix extract was relatively high and the concentrations of Ca, Mg, Fe, Na, Mn, and Zn were as follows: 275.3 ㎎%, 281.3 ㎎%, 119.4 ㎎%, 37.75 ㎎%, 10.43 ㎎% and 3.11 ㎎%, respectively. These results suggest that the Achyranthis Radix extract might have a possible positive effect for medical and edible purposes.
