The lipophilic fraction profile of several tree legume species' mature seeds was investigated, revealing their rich content of oil and bioactive compounds, making them potential sources of high nutritional value oils.
Several tree legume species' (Caesalpinia pulcherrima, Enterolobium cyclocarpum, Leucaena leucocephala, Pithecellobium dulce, Samanea saman, Sesbania grandiflora and Tamarindus indica) mature seeds were investigated for their lipophilic fraction profile. The oil yield ranged 2.1-14.9%. Linoleic acid was generally dominant (31.86-62.28%), followed by oleic (14.95-33.84%) and palmitic (7.21-17.54%) acid. Total tocochromanol content ranged 41.7-326.0 mg 100 g(-1) oil. Tocopherols (Ts), especially alpha-T (23.0-197.8 mg 100 g(-1) oil) and gamma-T (7.3-264.0 mg 100 g(-1) oil), dominated, and the seeds either did not contain tocotrienols or the content was negligible. Total carotenoid content ranged 2.1-11.8 mg 100 g(-1) oil. Only C. pulcherrima and P. dulce contained squalene. The total sterol content ranged 94-1810 mg 100 g(-1) oil, and the seeds contained mostly beta-sitosterol, Delta 5-stigmasterol, campesterol and cycloartenol. Although the oil yield is too low for commercial oil production, some of the studied species (C. pulcherrima, L. leucocephala and T. indica) could be considered as bioactive compound-rich oil sources.
