Abstract:

When Balb/C mice that were fed with red glutinous rice, white ordinary rice, or commercially available standard food were inoculated with syngeneic Meth/A lymphoma cells i.p., the group fed the red rice survived longer than the other two groups. In order to determine if the anthocyanins contained in red-coloured seeds and fruit rinds were responsible for the tumor suppressive effect, we added anthocyanins extracted from grape rinds and glutinous red rice to petri dishes that had been seeded with HCT-15 cells. After 4 days of culture, cell counts were made. These anthocyanins were not effective in suppressing the tumor growth. However, anthocyanidins, which were generated by keeping anthocyanins in 5 to 6% HC1 methanol for 5 to 6 hours, were effective in the suppression of tumor growth. Flowcytometric histograms were made after 2 days of culture with these bioflavonoids. The histogram of cells treated with crude anthocyanin was similar to that of the control. Hydrolyzed anthocyanidins gave the elevation of S phase, suggesting a block in the step from S-phase to G2-phase. It seemed that the anthocyanidins contained in the grape rinds and red rice were effective on the suppression of cell growth as observed previously for anthocyanins extracted from the petals of higher plants.
