PROXIMATE ANALYSIS, ANTIOXIDANT ACTIVITY OF ABELMOSCHUS ESCULENTUS (L) FLOWER EXTRACT
Sangavi S.* and Suja Pandian R.
ABSTRACT Methanol extract of Abelmoschus esculentus (L) flower was investigated for proximate analysis and antioxidant activity tests. Proximate analysis of the flowers of Abelmoschus esculantus. (L) revealed to contain carbohydrate, protein, fat, fiber, ash and moisture content The moisture content, total ash, carbohydrate value were 7.27%, 14.55%, 47.69% respectively. For the evaluation of antioxidant activity, five complementary test systems namely 1,1-diphenyl-2- picrylhydrazyl (DPPH), reducing power assay, total antioxidant capacity, Nitric oxide and ABTS+ activity determination methods were used. Methanol extract revealed higher Nitric oxide scavenging activity (68.01 ± 0.02), DPPH (50.01 ± 0.02) and ABTS+(48.01 ± 0.01 AAE/g) but lower reducing power activity than other extracts at 500μg/ml concentration. Keywords: Abelmoschus esculentus (L), Proximate analysis, Antioxidant activity. [Download Article] [Download Certifiate] |
