AIM: This work has been designed to evaluate the anti-proliferative and cytostatic effects of Citrus sinensis (orange) fruit juice on rapidly proliferating cells.
MATERIALS AND METHODS: The study was carried out on the seeds of Sorghum bicolor for 72 h. The mean radicle length (mm) of the seeds was taken at 48 and 72 h.
RESULT: The result showed that when compared with the control, methotrexate, the standard drug showed a significant (P<0.001) anti-proliferative effect throughout the experiment. The inhibition of the radicle growth was more after 72 h (87.42%). At a dose of 5% (v/v), the juice showed a slightly significant (P<0.05) effect affect after 72 h; however, there was no significant effect at 48 h. The juice at doses of 10% and 20% (v/v) showed a highly significant (P<0.001) anti-proliferative effect throughout the experiment; however, the percentage inhibitions were higher at 72 h. At 72 h, the percentage inhibition for juice at 10% (v/v) was 72.37% and at 20% (v/v) was 91.96%. The concentrations of 40% and 60% (v/v) showed cytostatic effects as no appreciable growth of the radicles of the seeds was observed throughout the experiment. The percentage inhibition for 40% (v/v) was 100% and 99.72% for 48 and 72 h, respectively, while that for the juice concentration of 60% (v/v) was 100% throughout the study.
CONCLUSION: The experiment has shown that C. sinensis fruit juice has a potential for causing both anti-proliferative and cytostatic effects on fast proliferating cells and hence cancerous cells.
