Antimicrobial, Antioxidant and Cytotoxic Activities of Glochidion multiloculare (Roxb. ex Willd.) Müll. Arg. (Euphorbiaceae)
Keywords:Glochidion, antimicrobial, brine shrimp lethality bioassay, total phenolic content, free radical scavenging
The methanol extract (ME) of the powdered bark of Glochidion multiloculare and its six vacuum liquid chromatographic (VLC) fractions (Fa-f) were investigated for antimicrobial, cytotoxic and antioxidant activities. Only fractions Fc and Fd showed mild antimicrobial activity. Significant free radical (DPPH) scavenging activity was found in Ff (IC50 value = 9.27±0.117 ?g/ml). The total phenolic content was measured involving Folin-Ciocalteu reagent and it was the highest in fraction Fe (187.00±1.74 mg of GAE/gm of sample). Cytotoxicity (LC50) by brine shrimp lethality bioassay was found to be significant for Fb (0.023±0.001 ?g/ml), Fc (0.3±0.01 ?g/ml) and Fd (0.117±0.0015 ?g/ml).
