12품종의 유색미에 대한 항변이원활성 및 항암활성을 in vitro에서 일품벼를 대조구로하여 조사하였다. 각 품종별 쌀겨를 0.5%의 TFA를 포함한 80% 에탄올, 또는 n-hexane으로 추출하여 각각 색소분획과 헥산분획을 제조한 다음, SOS chromotest를 이용하여 변이원에 대한 억제활성을 측정함과 동시에 각 분획의 DNA strand scission 및 발암 promoter에 대한 억제활성을 측정하여 이들이 가지는 발암억제효과를 평가하였다. 색소분획의 항변이원활성은 LK1B4-12-1-1 >상해향혈나 > HP833-1-3-1-1 > Chokoto14 > 자광도 > 자진 > 길림흑미 > Tiwan-Tsi-C > 흑진미 > Linsia-Shoea-Dau > 수원425 >수원415의 순서였으며, 헥산분획에서는 LK1B4-12-1-1 상해향혈나 > 일품벼 > HP833-1-3-1-1 > Chokoto14 > 자광도 > 자진 > Linsia-Shoea-Dau > Tiwan-Tsi-C > 흑진미 >수원425, 길림흑미 >수원415의 순서로 활성이 나타났다. 색소분획물이 가지는 DNA strand scission에 대한 억제활성을 조사한 실험결과, HP833-1-3-1-1 > Tiwan-Tsi-C > 자진 > Chokoto14 > 수원425 > 흑진미 > LK1B4-12-1-1 > 수원415 > 자광도 > 길림흑미 > Linsia-Shoea-Dau > 상해향혈나의 순서로 활성을 보인 반면, 헥산분획에서는 LK1B 4-12-1-1 > 수원415 > 길림흑미 > Chokoto14 > 흑진미 > 자진 > 수원425 > Tiwan-Tsi-C > 상해향혈나 > Linsia-Shoea-Dau >자광도 > HP833-1-3-1-1 > 일품벼의 순서로 활성을 보였다. 발암 promoter의 단기검출법을 이용한 실험결과, 발암 promotor TPA에 대한 색소분획물의 억제활성은 Linsia-Shoea-Dau > 길림흑미 > HP833-1-3-1-1, 수원425 > 흑진미 > 자진 > Chokoto 14 > 상해향혈나 > 수원415 > LK1B4-12-1-1 > Tiwan-Tsi-C > 자광도의 순서로 나타났다.

Abstract

Anticarcinogenicity of 12 kinds of colored rice cultivars was investigated in vitro with Ilpumbyeo as a control. Pigment and hexane fractions were prepared from the rice brans through extraction with 80% ethanol containing 0.5% TFA or n-hexane to use subsequent evaluation of their anticarcinogenic effect by determining inhibitory activity against DNA strand scission and tumor promotion, as well as antimutagenic activity using SOS chromotest system. Antimutagenic activity of the pigment fractions was revealed to decrease in order of LK1B4-12-1-1 > Sanghaehanghyulla > HP833-1-3-1-1 > Chokoto14 > Jagwangdo > Jajin > Kilmheugmi > Tiwan-Tsi-C > Heugjinmi > Linsia-Shoea-Dau > Suweon425 > Suweon415. The activity of the hexane fractions decreased in order of LK1B4-12-1-1 > Sanghaehyanghyulla>Ilpunibyeo > HP833-1-3-1-1 > Chokoto14 > Jagwangdo > Jajin > Linsia-Shoea-Dau >Tiwan-Tsi-C > Heugjinmi > Suweon425, Kilimheugmi > Suweon415. Results showed that inhibitory activity against DNA strand scission in the pigment fractions decreased in order of HP833-1-3-1-1 > Tiwan-Tsi-C > Jajin > Chokoto14 > Suweon425 > Heugjinmi > LK1B4-12-1-1 > Suweon415 > Jagwangdo > Kilimheugmi > Linsia-Shoea-Dau > Sanghaehyanghyulla. On the other hand, the activity of the hexane fractions decreased in order of LK1B4-12-1-1 > Suweon 415 > Kilimheugmi > Chokoto14 > Heugjinmi > Jajin > Suweon425 > Tiwan-Tsi-C > Sanghaehyanghyulla a Linsia-Shoea-Dau > Jagwangdo > HP833-1-3-1-1 > Ilpumbyeo. Experiment using the short-term assay for promotor substance showed that inhibitory activity contained in the pigment fractions against rumor promotor TPA decreased in order of Linsia-Shoea-Dau > Kilimheugmi > HP833-1-3-1-1, Suweon425 > Heugjinmi > Jajin > Chokoto14 > Sanghaehyanghylla > Suweon 415 > LK1B4-12-1-1 > Tiwan-Tsi-C > Jagwangdo.
