SummaryGranola bars were prepared using barley flakes, groundnut bits, cocoa powder, sucrose and/or sucrose alternatives (coconut sugar, fructooligosaccharide and inulin). Apart from sensory acceptance, nutritional composition, energy values and glycaemic responses (glycaemic index, GI and glycaemic load, GL) of the bars were evaluated. Physico‐chemical properties and sensorial acceptance of granola bar made with coconut sugar and fructooligosaccharide were on par with those made with sucrose. Further, all formulated granola bars, except with inulin, were intermediate moisture foods. GI of all five formulations of granola bars was <55; ranging between 51 and 54.9, corresponding to low glycaemic food. Granola bars with coconut sugar had high GL (≥20), while bars prepared with FOS, inulin and without sugar were in the medium range (>10 to <20). Effect of choice of raw materials, complexity of matrix structure and particle size of ingredients on GI and GL of the bars is explained.

Many beneficial medicinal products are used to treat various serious diseases and disorders like diabetes, cancer and cardiovascular diseases without side effects. Hence our study focused to investigate the phytochemical analysis, quantification of bioactive compounds (alkaloid, phenols, flavonoids), in vitro free radical scavenging activity, anti-inflammatory activity (Membrane stabilization assay), in vitro anti-diabetic activity by enzyme inhibition activity, glucose uptake assay in isolated rat hemi-diaphragm and in yeast cells and also record GC-MS profile of Erythrina variegata L. bark (methanolic extract) which has boundless medicinal properties. The results of this study showed the evidence that the extracts when tested for their phytochemicals and free radical scavenging activity were found to have considerable antioxidant potential. This plant also exhibit better in vitro enzyme inhibitory activity, inhibition of non-enzymatic glycosylation of hemoglobin, in vitro anti-diabetic activity proved by glucose uptake assays and anti-inflammatory activity. GC-MS analysis of methanolic extract of Erythrina variegata L. bark revealed the presence of 58 compounds which are responsible for pharmacological activities. The results of this study indicate that the methanolic extract of Erythrina variegata L. bark has significant pharmacological properties.
