Abstract
Present study have been performed to develop Bulnesia sarmienti as a functional food. Methanol, n-hexane, chloroform, ethyl acetate and butanol extracts of Bulnesia sarmienti contained total phenol by 5.81 to 7.47%. It is high content than fruits which were known as high contests of total phenol. The electron donating ability of the extract of Bulnesia sarmienti were increased along with increasing concentrations of extracts. At $500{\mu}g/mL\;and\;1000{\mu}g/mL$, the all extracts showde more than 80% of scavenging abilities, which means the equal effect of the antioxidant, BHT. Nitrite scavenging abilities were measured as follows: methanol, butanol, 5.53, 5.77% at $100{\mu}g/mL$, respectively. The ethyl acetate extract was 73.29% at $1000{\mu}g/mL$ which showed the highest activity and methanol, butanol, n-hexane, chloroform and water extract were 65.65, 65.02, 47.49, 52.51, 45.54% which also showed relatively high activities. The growth inhibitory effects of each solvent extract on tumor cell were as follows: test against SUN-1, the gastric carcinoma cell, exhibited the highest inhibitory effects at $100{\mu}g/mL$ where the n-hexane extract was 61.6%. The ethyl acetate and water extracts did not revealed any inhibitory effects. Hela, the uterine carcinoma cell, exhibited the highest inhibitory effects at $100{\mu}g/mL$ where the n-hexane extract was 75.1%. The water extracts did not revealed any inhibitory effects. HT-29, the colon carcinoma cell, also exhibited the highest inhibitory effects at $100{\mu}g/mL$ where n-hexane extract was 57.4%. In conclusion, Bulnesia sarmienti have been shown the antioxidant and antitumor effects, and that it is expected to be developed as functional foods.
이 연구에서는 Bulnesia sarmienti의 기능성 식품으로서의 이용성을 증대시키기 위하여 각 용매별 분획추출물의 항산화 효과와 MTT검색법을 사용한 항암 효과를 측정하였다. 총 페놀 함량은 methanol, n-hexane, chloroform, ethyl acetate, butanol, 물 추출물에서 각각 6.85, 5.81, 6.30, 7.47, 6.48, 4.82%로 나타났다. 용매분획별 총 페놀 함량은 ethyl acetate추출물에서 가장 높게 나왔고, 비교적 총 페놀 함량이 높은$(0.10{\sim}4.55%)$ 과일류보다도 더 높았다. 전자공여능은 모든 용매추출물에서 농도가 높을수록 그 효과가 증가하였으며 $500{\mu}g/mL\;1000{\mu}g/mL$에서는 모든 추출물에서 80%이상의 높은 소거능을 보여 합성항산 화제인 BHT와 동등한 효과를 보였다. 아질산염 소거능 측정결과, $100{\mu}g/mL$에서 methanol, butanol, ethyl acetate, n-hexean, chloroform, 물 추출물은 각각 4.43, 12.55, 16.72, 1.86, 5.53, 5.77%로 낮은 활성이 나타났다. $500{\mu}g/mL$에서 methanol, butanol, ethyl acetate, n-hexean, chloroform, 물 추출물은 38.52, 33.39, 47.41, 21.17, 31.74, 18.02%로 $100{\mu}g/mL$에서보다 활성이 증가하였고, $1000{\mu}g/mL$에서는 ethyl acetate추출물이 73.29%로 가장 높은 활성을 나타내었다. Methanol, butanol, n-hexean, chloroform, 물 추출물은 각각 65.65, 65.02, 47.49, 52.51, 45.54%로 비교적 높은 활성을 보였다. 추출용매에 따른 암세포의 성장억제효과를 보면 위암세포인 SNU-1은 $100{\mu}g/mL$에서 n-hexane추출물이 61.6%로 가장 높은 억제효과를 나타내었고, ethyl acetate 와 물 추출물은 억제효과가 없었다. 자궁암세포인 Hela는 $100{\mu}g/mL$에서 n-hexane추출물이 75.1%로 가장 높은 억제효과를 나타내었고, 물 추출물은 억제효과가 없었다. 대장암세포인 HT-29도 $100{\mu}g/mL$에서 n-hexane추출물이 57.4%로 가장 높은 억제효과를 나타내었다. 이상의 결과를 종합해 보면, Bulnesia sarmienti는 항산화 및 항암효과가 있는 것으로 판단되며 기능성 식품으로서의 개발가능성을 기대할 수 있을 것으로 생각된다.
