| Abstract: | Canna edulis
Ker- Gawl., found in the sub-Himalayan region contains starchy rhizome having
economic importance in terms of food and herbal medicine. Correlation of
phytochemical characteristics and antioxidative properties have been studied in
hot and cold extracts of C. edulis
rhizome. Antioxidants, BHT, quercetin, gallic acid and ascorbic acid
equivalents have been determined using spectrophotometer. Hydrogen peroxide
scavenging ability and reducing power properties have been used to define in
vitro radical scavenging activity of both extracts. Total phenol and
flavonoid contents were highest in hot extract (42.71 mg GAE/g and
21.92 mg QE/g) than cold extract (33.7 mg GAE/g and 15.12 mg QE/g). IC50
value of DPPH and H2O2 were also observed to be higher in
hot extract. The electron donation ability (EDA) of the hot extract (500 µg/ml)
demonstrated stronger activity than cold extract (400 µg/ml). Further
evaluation of free radicals was done by determining the specific Rf value of
bioactive components through TLC. Thus the hot rhizome extract of C. edulis exerts
more effective antioxidant property as compared to cold extract. |
