ANTIMICROBIAL POTENTIAL OF CRUDE EXTRACTS AND FATTY ACID FRACTIONS OF FOUR PTERIDOPHYTE SPECIES FROM ASSAM, NORTHEAST INDIA, AND THEIR IDENTIFICATION BY GC-MSAbstract
Fatty acids produced by plants protect themselves from pathogens, such as multidrug-resistant bacteria. In the present work, crude extracts, and fatty acid fractions of four pteridophyte species from Assam, Northeast India, were evaluated for their antimicrobial properties, and the bioactive compounds were identified using GC-MS analysis. The crude extract of Pteris semipinnata (Ps), Lygodium microphyllum (Lm), Lycodium flexuosum (Lf), and Lycopodiella cernua (Lc) was found to possess antibacterial and antifungal activities. The lowest MIC and MBC values were 0.25 mg/ml and 0.5 mg/ml for the fatty acid fractions against most of the microbial test strains. The GCMS analysis revealed 21 compounds in Ps, 35 in Lm, 33 in Lc, and 52 in Lf fractions. The present work supports the use of fern species in traditional medicine and therapies.
