Andiroba
oil is primarily composed of fatty acids including oleic, palmitic,
stearic, and linoleic acids. Linoleic acid is an essential fatty acid
required for many biological pathways. However, it cannot be
synthesized by animals it is obtained through diet only. It serves in
cell signaling and is positively linked to skin health.
Andiroba
bark, oil, and leaves also contains limonoids, including a novel type
andirobin (ROY et al, 2006). Limonoids are currently being
investigated for a variety of therapeutic effects such as antiviral,
antifungal, antibacterial, antibacterial, antimalarial and
chemotherapy. Some are also utilized as an insecticide.
