Evaluation of Antioxidant, Analgesic and Cytotoxic Activities of Typha angustata L. Root

Abstract

Ethanolic extract of the root of Typha angustata was evaluated for antioxidant, analgesic and
cytotoxic activities. T. angustata extract exhibited DPPH free radical scavenging activity with IC50 value of 124.96
± 0.93 μg/ml. The total phenolic and tannin content were found to be 596.73 ± 1 mg GAE/100 g and 319.68 ± 64
mg GAE/100 g of dried plant material, respectively. Analgesic activity was determined using acetic acid induced
writhing inhibition in mice model. The root extract, at doses of 250 mg/kg and 500 mg/kg body weight, showed
inhibition of writhing reflex by 33.55% (p < 0.01) and 56.78% (p<0.001), respectively. Cytotoxicity of the extract
was measured by brine shrimp lethality bioassay where the LC50 against brine shrimp nauplii was found to be
41.54μg/ml.
