Abstract: Lichens are fungi that live in intimate symbiotic association with green algae or cyanobacteria. Nine lichen species were collected and identified as Flavoparmelia caperata (L.) Ach., Roccella montagnei Bèl. Emend. Awas., Teloschistes flavicans (Swartz) Norm., Physcia aipolia (Ehrh. ex Humb.) Furnr., Parmotrema austrosinensis (Zahlbr.) Hale, P. grayanum (Hue) Hale, P. tinctorum Nyl., P. reticulatum (Taylor) Choisy and Usnea subflorida (Zahlbr.) Motyka. From which 45 extracts were prepared using Petroleum ether, Chloroform, Ethyl acetate, Acetone and Methanol solvents. Preliminary phytochemical screening for the presence of Tannins, Alkaloids, Saponins, Glycosides, Flavonoids, Proteins, Triterpenes, Carbohydrates and Steroids was carried out on aforesaid extracts. Important phytochemicals like Tannins, Proteins, Carbohydrates and Steroids were present in most of the lichen extracts tested. Petroleum ether and Chloroform extracts did not show any phytochemicals. Saponins were present only in U. subflorida. Methanolic extract was more active and showed almost all tested phytochemicals in all the lichen samples.
