초록

The nutritional composition of the white lotus(Nelumbo nucifera Gaertn) leaf are moisture(1.87±0.06%), crude ash (9.57±0.07%), crude protein(15.53±0.4%) and crude lipid(2.42±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±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 IC50 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 ㎍/mL respectively. The IC50 values of the hydroxyl radical scavenging ability of the ethanol extract, ethylacetate, butanol and water fraction were 390, 574, 327 and 378 ㎍/mL respectively.
