Background: Interest in novel sources of edible and vegetable oils have been growing due to
the growing population and its accompanying energy needs. The present study investigates the physicochemical
characteristics, the antioxidant property and antibacterial activity of the vegetable oil extracted
from Alocasia fornicata collected from Mizoram, India. This vegetable oil could potentially serve as a
highly valuable and cost-effective supplement.
Method: The fixed oil was extracted by using Soxhlet extractor and it was subjected to various preliminary
phytochemical and physicochemical tests including specific gravity, viscosity, iodine number, acid
value, saponification number and peroxide value. The antibacterial effects were estimated against different
pathogenic strains such as Klebsiella pneumonia, Pseudomonas aeruginosa, Bacillus subtillis and
Escherichia coli following disc diffusion method. Antioxidant activity of the fixed oil was evaluated by
DPPH scavenging activity and compared against a standard ascorbic acid.
Results: The yield of the fixed oil was found to be 8.39%. Results from various tests showed that the
fixed oil exhibit a positive test for sterols and terpenoids, and also possess certain antibacterial and antioxidant
properties. The scavenging property was also increased in a dose dependent manner. The IC50
value for the DPPH scavenging activity of the oil was also found to be 174.26 µg/mL.
Conclusion: Crude vegetable oil was extracted from the spadix of Alocasia fornicata and its property
was reported for the first time. The oil was found to exhibit properties that are typical of vegetable oils.
The oil also possesses antioxidant and antimicrobial property which indicates its applicability in food
and other industries.
