  • The nutritional composition of the white lotus(Nelumbo nucifera Gaertn) leaf are moisture($1.87{\pm}0.06%$), crude ash($9.57{\pm}0.07%$), crude protein($15.53{\pm}0.4%$) and crude lipid($2.42{\pm}0.1%$) per 100g. The highest mineral content was K and Ca. The principal free sugars in the white lotus leaf was sucrose, fructose and glucose. The total phenolics compounds evidenced maximal levels of $8,842.73{\pm}20.57\;g/100g$. DPPH and hydroxyl radical of scavenging ability of each sample tended to increase with increasing degrees of the sample concentration. The $IC_{50}$ values of the ethanol extract, n-hexane, chloroform, ethylacetate, butanol and water fraction from the white lotus leaf to DPPH radicals were 5.65, 8.5, 8.27, 2.03, 2.3 and $13.7\;{\mu}g/mL$ respectively. The $IC_{50}$ values of the hydroxyl radical scavenging ability of the ethanol extract, ethylacetate, butanol and water fraction were 390, 574, 327 and $378\;{\mu}g/mL$ respectively.
