Anthelmintic and Antioxidant activity of Aqueous Ethanolic Extract of Erythrina subumbrans (Hassk.) Merr.

Abstract

Aqueous Ethanolic extract of vegetative (leaf) part of herbal plant Erythrina subumbrans (Hassk.) was assessed for Anthelmintic and Antioxidant activity. The obtained crude extract was prepared in different concentration, i.e., 50 and 100 mg/mL, against the standard Piperazine citrate, i.e., 10mg/mL for anthelmintic activity. Pheretima posthuma test worms were used during the study and the anthelmintic activity was evaluated based on Paralysis and Death time.  The average paralysis and death time of standard is 1.4 & 39.59 min (10mg/mL) compared to sample 5.3 & 65.09 min (50mg/mL); 2.5 & 54.08 min (100mg/mL). From the data, aqueous ethanolic extract possesses promising anthelmintic activity compared to piperazine citrate standard. Similarly, antioxidant activity was evaluated for sample at different concentration ranging from 5, 10, 20, 40, 80, 160, and 320 µg/ml premixed with 2.5mL of 0.0135mM DPPH solution. Ascorbic acid was used as a standard and treated in a similar way as that of a sample. Control samples were also prepared without standard and sample solutions.  Prepared solutions were vortexed and kept at benchtop condition for 30 minutes and absorbance was measured at 517 nm in a UV-Vis spectrophotometer. The absorbance pattern of the sample is not comparable with that of the standard solution at the same concentration. Aqueous ethanolic extract with IC₅₀ (half maximal inhibitory concentration) value is >320 µg/mL against standard Ascorbic acid with an IC₅₀ value of 15.5µg/ml. Which witness the crude extract possess less antioxidant activity.
