Chemical and antimicrobial examination of the fixed oil from the seeds of Adenanthera pavonina Linn.

The seeds of Adenanthera pavonina linn. have been found to contain fixed oil (7.5%), crude protein (4.5%), reducing sugars (3.16%) as glucose and unsaponifiable matter (1.36%). The deep-brownish yellow fixed oil has been found to be :he glyceride of palmitic (19.06%), stearic (3.66%), arachidic (4.53%) and lignoceric (11.05%) as saturated (38.24%) fatty acids and oleic (24.1%) and linoleic (37.04%) as unsaturated (61.16%) fatty acids. The unsaponifiable matter consists of stigmasterol. The oil has shown feeble activity (comparable to achromycin/streptomycin) against Bacillus anthracis, Salmonella paratyphi and B. mycoides. It is totally ineffective against the rest of the test gram positive and gram negative plant and/or animal pathogenic bacteria.
