Phymatosorus scolopendria (Burm. F.) Pic. Serm. belongs to the family Polypodiaceae which is commonly known as musk-fern or wartfern. Medicinally, the experimental plant possesses insect repellent, antiinflammatory and bronchodilator activity and hence used ethnomedicinally by tribal people, but was not explored for its bioactive compounds. Hence, the objective of this study was to determine the bioactive compounds present in the methanolic extract of Phymatosorus scolopendria by Gas Chromatography-Mass Spectrum. The methanolic extract of the experimental plant revealed the presence of four phytoconstituents, namely dodecanoic acid, 1,2,3-propanetriyl ester, myristic acid vinyl ester, 4nitrophenyl laurate and hexadecanoic acid, 4-nitrophenyl ester with peak values 8.98, 53.29, 26.91 & 10.82. The predicted biological activities for the present compounds identified when referred in the literature shows antioxidant, antibacterial, antiviral, candidicidal, hypocholestrolemic, antiarthritic, hepatoprotective, mosquito repellent, antimicrobial, anticancer and cosmetics. The compounds were identified by comparing their retention time and peak area with that of literature and interpretation of mass spectra. The research could be continued to find out the therapeutic importance of all the compounds in future.
