Quantification of phenolic compounds and antioxidant capacity of an underutilized Indian fruit: Rayan [Manilkara hexandra (Roxb.) Dubard]

Publication date: Available online 6 December 2016 Source:Food Science and Human Wellness Author(s): Bhumi Parikh, V.H. Patel The fruit of Manilkara hexandra (Roxb.) Dubard is one of the most underutilized fruits of India and in Gujarat state it is popularly known as ‘Rayan’. The fruit and seed of Rayan were analysed for their total phenolic and flavonoid content, phenolic compounds and total antioxidant capacity with six different assay methods. The results of these analyses indicated that the methanolic extract of Rayan fruit proved to be a good source of phenolic (811.3mg GAE/100g fw) and flavonoid (485.56mg RE/100g fw) content. Also, eleven known phenolic compounds were tentatively identified for the first time from the fruit and seed of Rayan. The LC–MS/MS analysis of fruit revealed the presence of major phenolic compounds such as gallic acid, quercetin and kaempferol, while quercetin, gallic acid and vanillic acid in seed. The presence of quercetin suggests health benefits. The fruit of Rayan also proved the most important source of antioxidants as measured by FRAP, RPA, DPPHRSA, ABTSRSA and HRSA except NORSA in comparison with that of seed. The current study explains the importance of M.hexandra which is comparatively a good source of antioxidants such as phenols and flavonoids when included in the diet.
