Abstract
The increasing concerns regarding environmental pollution,
herbicide-resistant weeds, and health hazards associated with synthetic
agrochemicals have intensified the search for eco-friendly alternatives for
sustainable agriculture. Allelopathy, a biological phenomenon involving the
release of bioactive compounds by plants, offers considerable potential for the
development of natural herbicides and biopesticides. The dried and powdered
plant material was subjected to Soxhlet extraction using 70% aqueous ethanol.
The obtained extract was analyzed by Gas Chromatography-Mass Spectrometry
(GC-MS) and the compounds were identified by comparing their mass spectra with
NIST-08 and WILEY-7 library databases. GC–MS analysis revealed the presence of
37 phytochemical constituents comprising both major and minor metabolites.
Among the identified compounds, 6-undecyl-5,6-dihydro-2H-pyran-2-one (16.51%)
and 1-hexacosanol (14.63%) were the predominant constituents. Other important
bioactive compounds detected included neophytadiene, 2,4-di-tert-butylphenol,
phytol, tetradecanoic acid, n-hexadecanoic acid and squalene. These metabolites
are reported to possess insecticidal, antimicrobial, antifungal, larvicidal,
nematicidal, repellent and allelopathic properties. The occurrence of these
compounds supports the pesticidal and growth-inhibitory potential of P.
pinnata and highlights its value as a source of natural bioactive agents.
The findings demonstrate that Pongamia pinnata is rich in phytochemicals
with promising biopesticidal and allelopathic activities. The identified
compounds may contribute to the development of environmentally safe botanical
pesticides and bioherbicides, providing sustainable alternatives to synthetic
agrochemicals for integrated pest and weed management programs.
