초록

국산 미생물 발효차의 폴리페놀 색소성분들인 데아플라빈(TF)과 데아루비긴(TR) 및 EGCG를 macrophage cell line (RAW264.7에 적용하여 nitric oxide 합성 및 사이토카인 생성을 평가하였다. 사이토카인 생성은 TF, TR 및 EGCG를 RAW264.5 cell에 적용하였을 때, $80\;{\mu}g/ml$ 농도에서 대조군과 LPS 촉진 처리에 비하여 nitric oxide 생성은 약 1.5배 증가하였다. IL-6, $TNF-{\alpha}$ 및 GM-CSF는 TF, TR 및 EGCG 농도에 의존적으로 증가하였다. $TNF-{\alpha}$ 생성은 크게 증가하였으며, 이는 TF, TR 및 EGCG가 사이토카인 생성을 통하여 면역증강 효과를 가질 것으로 나타났다 TF, TR 및 EGCG는 총 페놀 함량에 비례하여 항산화능을 나타내었으며, 암세포 증식을 유의적으로 억제하였다. 이들 폴리페놀물질의 억제효과는 그 성분들의 항암촉진작용 및 항산화활성에 의한 것으로 판단된다.

Theaflavins (TF) and thearubigins (TR) are constituents of tea pigments which are polyphenols derived from Korean fermentation tea. After TF, TR and [(-) epigallocatechin-3-gallate](EGCG) have been applied to macrophage cell line (RAW264.7) nitric oxide (NO) synthesis and cytokines production were estimated. Cytokines production by enzyme linked immune-sorbent assay (ELISA) determined. NO production was increased by about 1.5-folds at the dose of $80\;{\mu}g/ml$ compared to control and lipopolysaccharide (LPS) stimulation when TF, TR and EGCG were applied to a RAW264.7 cell. Interleukin-6 (IL-6), Tumor necrosis factor ($TNF-{\alpha}$) and granulocyte-macrophage colony stimulating factor (GM-CSF) increased depended on concentrations of TF, TR and EGCG. The production of tumor necrosis $factor-{\alpha}$ increased highly in TR, TF and EGCG group with LPS. These results suggest that TF, TR and EGCG have immune-enhancement effect through the cytokine production. TF, TR and EGCG inhibited cancer cell viability, the anticancer effect of these polyphenols may explain the anti-tumor promotion action and antioxidant activity of these tea constituents.
