Phytochemical content, antioxidant activity and reducing power of five ethnic medicinal plants of Manipur was analysed to study the antioxidant content commonly used by the traditional healers for the treatment of different inflammatory diseases and ailments. Antioxidant activity of methanolic extracts of five medicinal plants was investigated by using DPPH method which ranged from 47.82±0.041 per cent to 72.62±0.08 per cent inhibition. The phytochemical contents like total alkaloids, total flavonoids, total phenol, total carotenoids content ranged from 5.95±0.01 to 16.11±0.01 mg caffeine/100g on dry weight, 34.95±0.02 to 228.15±0.02 mg quercetin (QE)/100g on dry weight, 88.46±0.01 to 225.50±0.01 mg catechol equivalents (CE)/100g on dry weight, 0.81±0.005 to 3.80±0.005 mg/100g, respectively. Pearson correlation revealed a positive correlation between total phenol content, total flavonoids content, total carotenoids content and free radical scavenging activity (DPPH) of five medicinal plants extracts. However a negative correlation was found between total alkaloids content and free radical scavenging activity of medicinal plants extracts. The reducing power five medicinal plants extracts was statistically significant and positively correlated with DPPH free radical scavenging activity (r = 0.651; p<0.01). The study revealed that the plants with higher antioxidant activity (DPPH) showed high absorbance. Higher absorbance indicates more reducing power.Keywords

Diabetes is global health disorder affecting millions of people worldwide with the largest number of diabetic adults in India ranging around 61.3 million people. Use of indigenous foods has been advocated to reduce the incidence of chronic, diet related non-communicable diseases such as diabetes, obesity and CVD. In the present study an approach was made to develop and assess the functional efficacy of sorghum based composite flour mix for a period of 15 days on blood glucose level of alloxan induced diabetes rats. Out of all the seven groups, Group A showed no significant improvement in the blood sugar level at the end of the supplementation period, Group B showed significant increase in the blood glucose level while Group C showed significant decrease in the blood glucose level along with Groups D, E, F and G fed with sorghum based composite flour mix showed significant decrease in the blood sugar level. Thus it can be concluded that the blood glucose lowering effect of sorghum based composite flour may be due to the in situ composition of the composite flour mix which are potential sources of dietary fibres like cellulose, lignin, phytonutrients including tannins, phenolic acids, anthocyanins, phytosterols, polyphenols, and policosanols.Â
