Abstract
|
|
|
|
Physiological activities of mistletoe extracts were examined. Total polyphenol contents, electro-donating ability, SOD-like activity, nitrite-scavenging ability and tyrosinase of mistletoe extracted with water, 50%, and 100% ethanol were determined. Total polyphenol contents of powder extracts were higher than slice extracts. EDAs showed over 90% at powder extracts. Especially mistletoe extracts with 50% ethanol were higher than water extracts. SOD-like activities of water, 50% and 100% ethanol extracts of all samples were 23.71～33.4% lower than those of 1.0% and 0.1% L-ascorbate solutions. Nitrite-scavenging activities at pH 1.2 were the most effective in water, 50% and 100% ethanol extracts. The results will be useful for understanding the physiolosical activities of mistletoe extracts.
