Abstract

This study was conducted to investigate the effect of 70% ethanol and water extract of Korean rough rice ('Ilpum', 'Goami2', 'Keunnun', 'Sulgaeng', 'Baegjinju', and 'Heugkwang') before and after germination on proliferation of human cancer cell lines (HepG2, PC-3, and MCF-7). Antiproliferation effect was higher in ethanol extract than water extract, and was higher in after germination. 'Ilpum' ethanol extract after germination showed higher anti-proliferation effect on HepG2 and PC-3 cell lines than before germination. The cell viability on HepG2 and PC-3 cell lines of 'Ilpum' ethanol extract after germination was 27.23% and 5.05% at 1.0 mg/mL, respectively. The anti-proliferation effect on MCF-7 was the highest in 'Ilpum' and 'Heugkwang' 70% ethanol extract after germination and those cell viabilities were 7.27% and 17.00% at 0.5 mg/mL, respectively. These results suggest that germinated rough rice might have a potentially preventive effect on human cancer cells.

발아 전후 6종의 벼(일품벼, 백진주벼, 설갱벼, 고아미2, 거대배아벼 및 흑광벼)의 물 및 에탄올 추출물에 대한 암세포주 성장억제효과를 간암세포주(HepG2), 전립선암세포주(PC-3) 및 유방암세포주(MCF-7)에 대하여 살펴보았다. 물추출물은 1 mg/mL 농도에서 3종의 암세포주에 대하여 118.97~44.85% 범위의 높은 생존율을 보여 항암효과가 낮았지만 에탄올 추출물은 90.82~5.04% 범위의 생존율을 보여 물 추출물보다 높은 암세포 성장억제 효과를 나타내었다. 일품벼 발아 전후 에탄올 추출물은 간암세포주에 대하여 1 mg/mL 농도에서 각각 27.23 및 42.36%의 생존율을 보여 발아 시 항암효과가 증가하였으며, 특히 유방암세포주에 대해서는 0.25 mg/mL 농도에서 각각 48.20 및 56.82%의 생존율을 보여 다른 품종보다 성장억제율이 높았다. 또한 설갱벼발아 전후 에탄올 추출물은 전립선암세포에 대하여 1 mg/mL 농도에서 각각 44.52 및 64.51%의 생존율을 보여 발아 항암효과가 증가하였다. 추후 항암활성 물질의 분리 동정과 메커니즘 규명에 대한 연구가 수행되어야 할 것으로 판단된다.
