“…cyclops contained about 6.83%, A. ligulata contained 9.04% and A. salicina contained the highest value (12.18%). Indeed, Youzbachi et al (2012) have reported that Acacia cyanophylla in Tunisia contains about 10% of oil. Other previous studies have reported that the oil content in Acacia species in India is between 4% and 10% (Sundar Rao et al, 1983;Maity and Mandal, 1990;Khan et al, 2012), and in 20 species of Acacia in Australia is between 3% and 22% (Brown et al, 1987).…”

Youzbachi et al (2012) have suggested that in 12 Tunisian A. cyanophylla, linoleic acid (61.11-65.45%) and oleic acid (19.67-22.85%) are the major fatty acids.

Recently, plant seeds that have not been enough explored and exploited are cheap sources of a lot of natural molecules for industrial applications. The aim of the present study was to evaluate for the first time the composition of fatty acids and triacylglycerols (TAG) of mature unexploited seeds of some Acacia species (Acacia cyclops, Acacia ligulata and Acacia salicina) harvested in Tunisia in order to reveal their potential for human consumption.Results showed that, Acacia seed oils were mainly unsaturated (more than 71%). The polyunsaturated fatty acids were the major fractions (52-68%) with the linoleic acid as the major fatty acid (more than 52%), followed by oleic acid (15-27%) as monounsaturated fatty acid. The TAG composition was significantly different among the three Acacia species. PLL, PLO, LnLO, OLL, OOL, and OOO were the major forms. Acacia seed oil could be used as potential source of oil with high industrial value; nevertheless in vivo tests are essential to confirm its safety before use. Ó 2015 The Authors.

Seeds from 12 Acacia cyanophylla ecotypes, harvested in Tunisia, were examined for their seed oil contents of carotenoids, tocopherols and phytosterols. The average carotenoid content (lutein and zeaxanthin) was ca. 102 mg kg−1 of total extracted lipids. Lutein (ca. 97 mg kg−1 of total extracted lipids) was usually more abundant than zeaxanthin (ca. 5 mg kg−1 of total extracted lipids). The mean total tocopherol content was ca. 704 mg kg−1 of total extracted lipids. The main isomer was α‐tocopherol, with more than 75 % of total tocopherols (ca. 528 mg kg−1 of total extracted lipids), followed by γ‐tocopherol (ca. 168 mg kg−1 of total extracted lipids) and δ‐tocopherol (ca. 86 mg kg−1 of total lipids). High levels of phytosterols (ca. 7.8 g kg−1 of total extracted lipids) were detected, among which β‐sitosterol was the most abundant (47 %). All these results highlight the richness of carotenoids, tocopherols and sterols in A. cyanophylla seed oil, and imply that this species might constitute a potential resource for the development of functional foods.

The goal of this study is to evaluate the chemical composition of the Prosopis farcta seeds. The Kjeldahl method revealed that the level of the total protein was ca. 18 % on a dry weight basis (DW). Gas chromatographic analysis revealed the presence of six fatty acids. Linoleic acid with 57.55 % was the major fatty acid, followed by oleic and palmitic acids (24.58 and 12.91 %, respectively). Total phenolic content was 1.71 mg GAE/g DW (GAE = gallic acid equivalents). Methanolic extracts showed important antioxidant properties. This work highlights the importance of P. farcta seeds as natural and inexpensive sources of protein, unsaturated fatty acid, and phenolic compounds for both cosmetic and pharmaceutical uses.

Unexploited Acacia cyanophylla seeds: potential food sources of ω6 fatty acids and antioxidants?

Abstract: The findings of this study confirm the presence of ω6 fatty acids at high levels in A. cyanophylla seeds. These metabolites could be used as such and/or extracted for the formulation of supplements and/or ingredients to provide a ratio close to the ideal for the ω3/ω6 balance.
