The study examined qualities including chlorophyll, total phenol, total flavonoid content and antioxidative activity in 7-year-old mistletoe that was artificially cultivated with Japanese apricots as the host. The chlorophyll a content of the artificially cultivated Japanese apricot mistletoe leaves was 7.67 mg/g (old leaves) and 3.17 mg/g (new leaves), while the chlorophyll b content was 0.80 ~ 3.53 mg/g and 1.31 ~ 3.56 mg/g. The carotenoid content of the Japanese apricot mistletoe leaves were in the range of 0.29 ~ 2.48 mg/g, and the old leaves (1.85 mg/g) had a carotenoid content 2.1 times higher than the new leaves (0.89 mg/g). The total polyphenol content of the leaves and nodes of the 7-year-old mistletoe was 60.22 mg/100 g TAE for the leaves and 35.50 mg/100 g TAE for the nodes. Among the host trees, polyphenol content was highest (81.44 mg/100 g TAE) in the old mistletoe leaves of the Quercus mongolica, while the total flavonoid content of the Japanese apricot mistletoe was higher in the new leaves (47.89 mg/100 g RUE) than the old leaves (42.19 mg/100 g RUE). The DPPH radical scavenging ability of the Japanese apricot mistletoe scored a low 22.4 ~ 28.5% in the leaves, but was relatively high in the nodes at 52.4 ~ 80.1%. In terms of 1mg/mL concentration, the new leaves (69.1%) and old leaves (82.3%) of the Quercus monglica mistletoe displayed the highest inhibition rate. Chestnut mistletoe displayed an inhibition rate of 21.9 ~ 31.9% for the leaves, and 35.0 ~ 63.8% for the nodes. These results indicate that Japanese apricot mistletoe would be substitute oak tree mistletoe as a source of bio-active property for functional food and medicine.
