Nutritional Evaluation of Calyces and Epi-Calyces from Two Variants of Hibiscus sabdariffa L.: A Comparison

Debaleena Kashyap, Pranjal Sarmah and Aniruddha Sarma

Abstract:
Hibiscus sabdariffa L. (Roselle; Malvaceae) has been used traditionally as food, in herbal drinks, in hot and cold beverages, as flavouring agent in the food industry and as herbal medicine. The calyx of the roselle plant has long been recognised as a source of antioxidants. The objective of this study was to evaluate antioxidant activity, free radical-scavenging and total phenolic content in calyces and epi-calyces of the roselle plant. Methanol extracts showed a positive correlation between phenolic content and antioxidant activity, as with the increase of their phenolic content (134.32±1.82 μg GAE mg-1 for the red variant and 154.60±1.54 μg GAE mg-1 for the white variant), the antioxidant activity of the of the two variants also increases (118.66±0.96 and 102.54±1.08 μg mL-1, respectively). So have the potential to be used as food antioxidants. Moreover, nutritionally both the variants are rich in protein, crude fibre, ascorbic acid.
