Seed of 34 cultivars of winged bean of different origin were evaluated for their nutritional composition and the antinutritional factor, the trypsin inhibitor. The values ranged from 14.1 17.6, 6.12-8.73, 21.94-34.89 and 30.86-39.05% for their fat, fibre, carbohydrate and protein contents, respectively. The protein content in defatted seed meal ranged from 33.4347.25%, whereas the trypsin inhibitor activity (TIA) registered a wide variation from 63-123 mg g-t with seed coat and 51-98 mg g-1 without seed coat. The strain selection-12 and NBRI selection contained the minimum TIA (63mgg-~), while the highest value (I23 mgg -1) was in variety V7, a 2-fold higher activity.

“…Several reports have been made on the fatty acid composition, and have noted the absence of parinaric acid (3). The present authors reportedd that winged bean lipid is a potential source of edible oil since it contains 90 triacylglycerol (triglyceride) and its fatty acid composition is characteristic of saturated long-chain fatty acids, such as behenic acid (18.5%), and lignoceric acid (4.2%) (4).…”

SummaryWinged beans were extracted with hexane and the extracted lipid was analyzed by HPLC for its triacylglycerol (triglyceride) compo sition on a Lichrosorb RP-18 column with acetonitrile-tetrahydrofuran -dichloromethane (6:2:1) solvent mixtures. The chromatography yielded more than 21 peaks, and each triacylglycerol was analyzed for fatty acids by GLC. The major triacylglycerols were found to be behenoyl-linoleoyl oleoylglycerol (21.3%), trioleoylglycerol (10.5%) and behenoyl-diole oylglycerol (15.6%). Winged bean oil was found to contain triacyl glycerols of larger ECN (equivalent carbon number) than soybean oil.

“…Thus, the hexane extracted oil also needs refining to ensure its safe use in food products (Rout et al 2014). Over all, the present analysis of P. tetragonolobus oil contained 75.5 % USFA and 21.9 % SFA, whereas soybean oil contained around 86 % of USFA and 14 % SFA (Garcia and Palmer 1979). Thus P. tetragonolobus fatty oil may be fulfilled a gap of high demand soybean oil.…”

“…Ekpenyong and Borchers (1980) have studied physicochemical properties including the fatty oil of Nigerian P.tetragonolobus seeds. Garcia and Palmer (1979) have carried out the similar study on five different varieties of P. tetragonolobus seeds including the Nigeria variety synonymously reported the chemical composition of fatty oil identified as oleic acid (35.04-41.01 %) and linoleic acid (15.28-31.77 %). However, no separation of linolenic acid and arachidic acid was reported.…”

Physicochemical analysis of Psophocarpus tetragonolobus (L.) DC seeds with fatty acids and total lipids compositions

Psophocarpus tetragonolobus (L.) DC. is a tropical legume with potential nutritional properties. In present study, the physical properties and proximate composition of the seeds were evaluated. Besides, the physico-chemical properties of fatty oil from fully mature seeds were also studied. The fatty oil compositions of immature, mature and fully mature seeds were evaluated by GC-FID, GC/MS and 1 H-NMR. The study revealed that, fatty oil from fully mature seeds contained high proportion of unsaturated fatty acids (75.5 %), whereas immature seeds contained higher percentage of saturated fatty acid (61.3 %). In addition, unsaponification matter (0.25 %) of fatty oil was identified as stigmasterol (66.4 %) and β-sitosterol (25.1 %). Total lipids of fully mature seeds were extracted and isolated as neutral, glyco-and phospholipids. Overall, the fatty oil of fully mature seeds was enriched with mono-unsaturated fatty acids (38.6 %) and poly-unsaturated fatty acids (36.9 %) without trans-fatty acids, thus meeting the edible oil standard.
