초록
Nelumbo nucifera (Lotus, N. nucifera) is a popular aqueous plant in Eastern Asia. Leaves (Nelumbinis Folium) of N. nucifera are traditionally used to disperse body heat during the summer and is said to increase essential body energies, according traditional Oriental Medicine, and are becoming popular as ingredient of healthy tea. In the recent years, since many synthetic antioxidants have been shown to have side effects, there has been an increase of interest in natural products as antioxidants in scavenging free radicals. In the present study, we first analyzed composition of Nelumbinis folium (NF), and evaluated the possible antioxidative activities of it’s ethanol extracts. Therefore, we measured the effects of NF on scavenging activities against DPPH radical, hydroxyl radical, superoxide radical and hydrogen peroxide. Consequently, 10 μg/mL of ethanol extract from NF exhibited higher scavenging activity coefficient than that of BHT against all. These results indicate that NF protects oxidative activities through scavenging of free radials.
Abstract
Nelumbo nucifera (Lotus, N. nucifera) is a popular aqueous plant in Eastern Asia.
