Polyrhachis vicina Roger (P. vicina) is a traditional medicinal edible black ant that has been used to treat a variety of conditions, including rheumatoid arthritis, hepatitis, and cancer. It’s also used as a functional ingredient in tonics. The active fraction of P. vicina (AFPR) has been shown to have a variety of pharmacological activities, including:
Inhibiting CRC growth: AFPR has been shown to inhibit CRC growth in vivo and in vitro.
Alleviating memory impairment: In a rat model of Alzheimer’s disease, AFPR improved memory function, preserved neuron structure, and suppressed Aβ deposition.
Activating ERK to cause necroptosis: AFPR has been shown to activate ERK to cause necroptosis in colorectal cancer.
AFPR is made up of 71.14% unsaturated fatty acids, including octadecenoic acid, heptadecenoic acid, and leinoleic acid, and 25.04% saturated fatty acids. A hydro-ethanolic extract of P. vicina also contains 60 bioactive components, including fatty acids, phenolic acids, flavonoids, organic acids, and nitrogen compounds.
