천연물들은 현재까지 합성 항산화제들을 대체하기 위하여 많은 연구가 이뤄지고 있다. 본 연구에서는 천연 항산화제로서 화장품과 바이오산업에 적용하기 위해 정금나무 열매 70% 아세톤 추출물의 항산화능을 측정하였다. 정금나무 열매의 항산화능을 확인하기 위하여 폴리페놀의 함량을 측정, 전자공여능, $ABTS{\cdot}^+$, nitric oxide, hydrogen peroxide들의 소거 측정을 분석하여 다음과 같은 결과를 얻었다. 폴리페놀의 총 함량은 55.972 mg TAE/g로 정량 되었다. 전자공여능 실험에서는 농도 의존적으로 DPPH radical 소거능이 증가 하였으며 500 ${\mu}g/ml$에서 98% 이상의 활성을 나타내어 양성 대조군인 BHA의 활성을 초과하는 것을 알 수 있었다. $ABTS{\cdot}^+$에 대한 소거활성은 500 ${\mu}g/ml$에서 66.7%의 결과로 나타났고, nitric oxide radical 소거능은 100 ${\mu}g/ml$에서 57%의 활성을 나타내었다. 또한 정금나무 열매 70% 아세톤 추출물의 hydrogen peroxide의 소거활성은 50 ${\mu}g/ml$에서 정금나무 열매 추출물은 70% 이상의 활성을 나타났으며, BHA 보다 높은 활성을 나타내었다. 천연물의 산업화 가능성에 있어 가장 중요한 것은 재료의 영속적인 수급과 적은 농도를 첨가하여도 높은 효과를 나타내는지의 여부이다. 매년 수확이 가능한 정금나무 열매를 이용한 본 연구의 결과에서 열매의 항산화능 확인 및 화장품 등 바이오산업에 천연항산화제 원료로서의 적용 가능성을 확인할 수 있었다.

In the course of finding Korean natural products with acetylcholinesterase (AChE) inhibitory activity, we found that a methanolic extract of the twigs of Vaccinium oldhami significantly inhibited AChE. Bioassay-guided fractionation of the methanolic extract resulted in the isolation of two compounds, taraxerol (1) and scopoletin (2), as active constituents. These compounds inhibited AChE activity in a dose-dependent manner, and the $IC_{50}$/ values of compounds 1 and 2 were 33.6 (79 $\muM$) and 10.0 (52 $\muM$) $\mu$g/mL, respectively.

Vaccinium oldhami Miq. is a Korean native tree, which is deciduous and shrub tree with broad leaf. It grows 1~4m in height generally. Ecologically, this tree grows well in shady place even in barren soil. Also, the tree has resistance to cold and dry, which tend to form a little community. This research investigates quantitative morphological characteristics of leaf and fruit among the V. oldhami in South Korea and then considers its relationship on the basis of raw data among the 10 populations. This study will give us invaluable information about growing conditions, reasonable management and breeding by selection of V. oldhami in South Korea. The main results obtained from this study are summarized as follows; Leaf size of Mudeung population was larger than other populations. Naebyeon population was smaller in size of the leaf than other populations. Anmyeondo population was larger in fruit characteristics compared with other populations and Deogyu population was the smallest among populations. According to cluster analysis based on the leaf and fruit morphological characteristics, the natural V. oldhami populations were classified into four groups such as the first group of Kumo population, the second group of Mudeung population, the third group of Anmyundo, Daedun, Doolyun population and the fourth group of the other five populations.
