곰의말채의 항암 및 면역활성을 탐색하고자 수피, 목부, 잎의 부위별 메탄올 추출물을 이용하여 연구를 수행하였다. 인간 정상 신장세포를 이용한 세포독성 실험에서 모든 추출물이 1.0mg/ml 농도의 첨가를 통해 대략 25% 이하의 세포독성을 나타내었다. 폐암세포인 A549와 유방암세포인 MCF-7을 이용한 항암실험에서 수피 추출물이 1.0mg/ml 농도의 첨가를 통해 각각 57.4%와 58.7%의 생육저해 활성을 보였다. 모든 추출 시료가 면역세포인 B세포와 T세포의 생육을 촉진하였는데, 특히 수피 추출물 첨가를 통해 B세포와 T세포의 생육이 5일째 대조군과 비교하여 각각 38.7%와 58.7%까지 증진되었다. 면역세포 분비물인 IL-6와 TNF-α의 분비량 측정에서도 수피 추출물 첨가군이 1.28×10?4 pg/cell, 1.38×10?4 pg/cell를 나타내며, 각각 0.86×10?4 pg/cell, 0.70×10?4을 나타낸 대조군에 비하여 유의적인 증가를 나타내었다. 또한 면역세포 분비물 첨가를 통한 NK-92MI세포 생육 증진에도 효과를 나타내는 것을 확인하였다. 이로써 곰의말채 추출 성분이 항암 및 면역활성에 유용한 성분을 함유하고 있으며, 특히 수피 추출물이 유의적으로 높은 활성을 나타내는 것으로 사료된다. Anticancer and immuno-modulatory activities of methanol extracts from different parts, bark, wood and leaf, of Cornus macrophylla Wall. were investigated in this study. All extracts at a concentration of 1.0mg/ml showed relativity low cytotoxicities on human normal kidney cell (HEK293) by approximately 25%. Bark extract of C. macrophylla showed the highest anticancer activity on human lung cancer cell line (A549) and human breast cancer cell line (MCF-7) by 57.4% and 58.7%, respectively, at a concentration of 1.0mg/ml. All extracts enhanced the growth of human B and T cells, showing 38.7% and 65.9% increase compared to control, respectively, by 5 days incubation with bark extract. The secretions of interleukin 6 (IL6) and tumor necrosis factor alpha (TNF-α) from human B and T cells were significantly increased by extracts, especially bark extract. B or T cell medium, which contains cytokines (IL 6 and TNF-α) secreted by bark extract treatment for 5 days, time-dependently enhanced the growth of NK-92MI cells with the maximal effect at 5th day of incubation. These results suggest that C. macrophylla, especially bark, has the potential for anticancer and immuno-modulatory activities.

To identify new antioxidative and anti-wrinkle ingredients, this study characterized the biological properties, including radical scavenging and elastase inhibition effects, of the crude 80% methanol extract, its subfractions, and the quercetrin isolated from Cornus macrophylla Wall growing in Jeju island. The elastase inhibition activity of the 80% methanol extract and the fractions of both ethyl acetate and butanol showed stronger inhibition activity than Areca catechu extract (used as a reference). The 80% methanol extract and ethyl acetate fraction exhibited free radical scavenging activity on DPPH radical and superoxide with IC50 values of 6.8 μg/mL, 6.2 μg/mL and 1.6 μg/mL, 0.02 μg/mL, respectively, which were stronger than that of butylated hydroxyanisole (9.1 μg/mL) or allopurinol (2.2 μg/mL) as a reference. The ethyl acetate fractions were further purified using a reverse-phase column and prep-HPLC to obtain quercetrin, and its structure was elucidated by NMR. Quercetrin showed significant effects on scavenging DPPH radical and superoxide. These results suggest that the extract of Cornus macrophylla Wall has a considerable potential as a cosmetic ingredient with antioxidative and anti-wrinkle effects. Quercetrin can be used as a functional reference.
