쑥과 솔잎을 각각 물과 70% 에탄올로서 추출하여 전자공여능과 아질산염 소거능을 조사하였다. 쑥 추출물의 전자공여능은 300-1,000ppm 농도에서 물추출물은 50-57%였으며, 에탄올추출물은 51-64%로서 에탄을 추출물이 우수하였다. 솔잎 추출물의 전자공여능은 물추출물은 100-500ppm에서 52-60%, 1,000ppm에서는 70%의 전자공여능을 나타내었으며 에탄을 추출물은 100-500ppm에서 68-71%, 1,000ppm에서는 약
Mugwort and pine needle were extracted with water and 70% ethanol. Electron donating ability(EDA) of extracts were ranged from 50% to 57% in mugwort water extract(MGW) and ranged from 51% to 64% in mugwort ethanol extract(MGE) at 300-1,000ppm. EDA of extracts were ranged from 52% to 60% in pine needle water extract(PNW) and ranged from 68% 71% in pine needle ethanol extract(PNE) at 100-500ppm. EDA of PNW was 70% and that of PNE was 77% at 1,00(ppm. Nitrite scavenging ability(NSA) of extracts measured at various pH(1.2, 3.0, 4.2, 6.0) was the highest in all extracts at pH 1.2 and decreased with increasing pH, suggesting it is pH dependent. NSA of mugwort extracts at 1,000ppm, water extract was 37% and ethanol extract was 27% at pH 1.2. NSA of pine needle extracts at 1,000ppm, water extract was 65%and ethanol extract was 53% at pH 1.2. EDA and NSA of pine needle extracts were higher than mugwort in both of water and ethanol extract. EDA of ethanol extracts were higher than water extracts while NSA of water extracts were higher than ethanol extracts in both of mugwort and pine needle.
