The present investigation has been carried out to determine the proximate composition, amino acids, metal contents, oil composition as well as the antioxidant capacity of the seeds of Ipomoea hederacea Jacq. and Lepidium sativum L. Proximate composition indicated a great difference in oil (14.09 ± 0.66, 28.03 ± 1.05) and fibre (16.55 ± 0.31, 6.75 ± 1.20) contents for I. hederacea and L. sativum, respectively. Fatty acid profile indicated that oleic acid (19.50 ± 0.37, 30.50 ± 0.16) and linoleic acid (52.09 ± 0.48, 8.60 ± 0.38) are the major fatty acids. γ-Tocopherol and δ-tocopherol (28.70 ± 0.14, 111.56 ± 0.37) were the most abundant in the seed oil of I. hederacea and L. sativum, respectively. Results of TEAC, FRAP and TRAP antioxidant assays indicated that L. sativum has much greater antioxidant potential than I. hederacea.

“…The data (Table 4) indicated that arginine (14.59 ± 0.16%), lysine (13.48 ± 0.07%), and histidines (11.36 ± 0.28%) are present in excessive amounts in seed, while glutamic acid (17.22 ± 0.42%) and aspartic acid (3.03 ± 0.90%) are present in the highest concentrations in pod. These results are comparable to those of earlier studies (44) for seed, despite differences due to different units involved.…”

“…Fatty acid composition (Table 6) indicated the presence of linoleic acid in highest contents (47.13 ± 0.82% and 52.39 ± 0.38%), while sufficient amounts of oleic acid (23.37 ± 0.62% and 32.00 ± 0.41%) and palmitic acid (17.02 ± 0.24% and 8.83 ± 0.82%) are also present in the seed and pod, respectively. Tocopherol contents (Table 7) are well in line with those reported earlier (44), and appreciable amounts of these constituents are present. α-Tocopherol was found in the highest amount (51.7 ± 0.26 mg/100 g and 35.99 ± 0.09 mg/100 g) in total tocopherol content while δ-tocopherol was found in the lowest amount (1.53 ± 0.74 mg/100 g and 0.04 ± 0.58 mg/100 g) for seeds and pods, respectively (Table 7).…”

“…Accordingly, Tables 1 and 2 contain data on the fatty acid profiles of several Albizia seed oils. The most reported fatty acid profile is that of A. lebbeck [20][21][22][23][24][25][26][27][28][29][30]; see Table 1. Fatty acid profiles of several other species, namely Albizia amara, Albizia harveyi, Albizia julibrissin, Albizia odoratissima, Albizia procera, Albizia saman, Albizia versicolor, and Albizia zygia have also been presented in the literature [19,23,24,[31][32][33][34][35][36][37][38][39][40][41] as listed in Table 2.…”

In this work, the fatty acid profiles of the seed oils of Albizia lebbeck and Albizia saman (Samanea saman) are reported. The oils were analyzed by GC, GC-MS and NMR. The most prominent fatty acid in both oils is linoleic acid (30-40%), followed by palmitic acid and oleic acid for A. lebbeck and oleic acid and behenic acid for A. saman. Both oils contain slightly more than 30% saturated fatty acids with stearic, eicosanoic and tetracosanoic acids present as well as odd-numbered saturated fatty acids in minor amounts. Furthermore, for the first time, epoxy fatty acids are reported in the fatty acid profiles of Albizia seed oils. Coronaric acid (9,10-epoxy-12(Z)-octadecenoic acid) is the major epoxy fatty acid at approximately 3-4% of the fatty acid profiles with minor amounts of vernolic (12,13-epoxy-9(Z)-octadecenoic acid) and 9,10-epoxystearic acids also detected. The results are compared to previous literature on the fatty acid profiles of other Albizia seed oils. The coronaric acid content of Albizia resembles that of Acacia species with both genera belonging to the Fabaceae family. The mass spectrum of the pyridylcarbinol (picolinyl) ester of coronaric acid is reported.
