Sugarcane (Saccharum officinarum L.) juice is widely consumed by the people of the tropics and subtropics. It has been used to cure jaundice and liver-related disorders in medicine. Its possible mechanism of action was examined in terms of antioxidant activity and phenolic contents. The antioxidant activity was assayed by using the scavenging of a stable 2, 2-diphenyl-1-picryl-hydrazyl (DPPH) radical at 517 nm. In addition, the phenolic content, reducing sugar, non-reducing sugar and Brix contents were measured to evaluate the biochemical variation. The juice from thirteen important genotypes of sugarcane was included in the study. Among these genotypes S-2003-CP-43-33, CP-77-400, SPF-213 and HSF-240 showed good antioxidant activities (IC50 values varied from 17.04 +/- 0.6 to 21.90 +/- 0.45 mu g/mL). Cluster analysis showed wide variation between the genotypes based on biochemical assays. HSF-240 and CP-43-33 showed 50 gene-linkage distances in clustering pattern.
