Abstract
This study evaluated variations in phytochemical composition and
antimicrobial activity of Moringa oleifera leaves collected in two
different seasons, Karkidakam and non-Karkidakam from Kerala, India. Qualitative
and quantitative phytochemical analyses were done using methanolic extracts,
while n-hexane extracts were evaluated using GC-MS. Antimicrobial activity was
assessed against selected bacterial and fungal pathogens using agar well
diffusion and radial growth inhibition assays. Results showed higher levels of
alkaloids, tannins and phenolic compounds in non-Karkidakam samples, whereas flavonoids
are found to be comparatively higher during the Karkidakam season. GC–MS
analysis revealed seasonal differences in fatty acids and their derivatives,
with hexadecanoic acid and octadecatrienoic acid as major constituents.
Antibacterial activity was observed mainly in Non-Karkidakam extracts, while
Karkidakam extracts showed stronger antifungal activity. The study demonstrates
that seasonal variation significantly influences phytochemical composition and
antimicrobial properties of Moringa oleifera leaves.
