Abstract

This report deals with studies related to phytochemical screening, antioxidant potential and
antibacterial activity of two macrolichens Acroscyphus sphaerophoroides Lev., a fruticose lichen
and Dirinaria consimilis (Stirton) D.D. Awasthi, a foliose lichen. Qualitative phytochemical
analysis showed the presence of alkaloids, terpenoids, saponins, glycosides, tannins and phenols.
Acroscyphus sphaerophoroides and Dirinaria consimilis showed relatively antioxidant activity
as revealed by DPPH study. A moderate iron chelation has been noted. Both the species showed
antibacterial activity against gram-positive bacterial strain Staphylococcus aureus.
Keywords: fruticose, foliose, acetone, methanol, DPPH, iron chelation, gram-positive
