“…The saturated fatty acids estimated were stearic (20.21-24.20%) and palmitic (3.20-5.29%). The fatty acid profiles evaluated in this study are not in complete agreement with the works reported (Lakshminarayana et al 1982;Armougom et al 1998). The fatty acid composition alters with the variety, soil, and climatic conditions (Egan et al 1981).…”

“…The moisture contents ranged from 7.62-8.20%, the low amount was found in Guti karela. Karela seeds contained 33.93-36.21%, of total lipids, which was lower than the value 47.50% reported by Lakshminarayana et al (1982). The ash contents were estimated to be 2.25-2.73%.…”

“…Some research works have been carried out on the seed oil and nutritional compositions of karela seed (Toyama & Tsuchiya 1936;Lakshminarayana et al 1982;Madaan & Lal 1984;Assubaie & El-Garawany 2004) but the information regarding these types of research works on different varieties of this plant cultivated in Bangladesh is very scanty. Hence the present investigations were highlighted with a view to find out the physico-chemical characteristics and fatty acid composition of seed oil and also some important nutrients and mineral contents of seeds obtained from three varieties of karela as a basis for comparison, all cultivated in homogeneous conditions in the experimental plot located at Rajshahi city, Bangladesh.…”

Farmers in rural areas of almost all the districts of Bangladesh cultivate different varieties of edible plant karela to satisfy nutritional requirements. Herein, we report on the characteristics of seed oils and nutrients and mineral contents of seeds from three varieties of karela. Most of the physicochemical characteristics were significantly (P < 0.05) affected with the samples tested. Seed oils of all varieties displayed a higher degree of unsaturation and in GLC reported herein, only five fatty acids were identified. The profiles of fatty acid composition were not wholly similar in all varieties in which unsaturated fatty acids represented more than 72%, α-eleostearic acid having been detected in the amount of 50.36-53.22%. Acylglycerol classes were estimated to be monoacylglycerols (1.18-2.01%), diacylglycerols (1.83-2.98%), and triacylglycerols (91.11-93.03%) whereas lipid classes included neutral lipids (86.83-91.09%), glycolipids (4.37-7.43%), and phospholipids (3.22-4.62%). Of the major energy producing nutrients, all varieties contained large amounts of lipid (33.93-36.21%) and protein (18.23-21.36%), and potentially useful amounts of calcium (383.45-440.96 µg/g), iron (41.10-45.03 µg/g), and other essential minerals. The nutrient information presented in this report should stimulate the local public health authorities in Bangladesh to consider the question of recommending the vegetable karela to be consumed by adults and children alike in Bangladesh, including pregnant women and others with higher than normal nutritional requirements.

“…glass column packed with 6% BDS (butanediol succinate polyesters) on solid support, Anakorm ABS (100/120) mesh. Analysis was carried out at isothermal column temperature 190 o C, injector and detector temperatures for GLC analysis were 230 o C. On the other hand, the oil from T. anguina seed was converted to methyl esters with NaOMe-MeOH and analysed by GLC (Model 5890, Hewlett Packard) equipped with a flame ionization detector and SE-30 column at 190 o C. The identification of punicic acid in T. anguina seed oil was achieved according to the methods described elsewhere [10,20].…”

ABSTRACT ABSTRACT. The core objective of this research was to determine the characteristics of oils, nutritional composition and antimicrobial activities of T. anguina and S. mahagoni seeds. Physicochemical characteristics of oils implied higher degree of unsaturation in T. anguina whereas, S. mahagoni oil contained appreciable level of unsaturation. Tri-acyl-glycerols and neutral lipids were found to be most abounded components recorded to 86.2 and 91.3% for T. anguina and 87.0 and 89.4% for S. mahagoni, respectively. GLC analysis showed the presence of fatty acids from series C16:0 to C18:3 for T. anguina and C16:0 to C20:0 for S. mahagoni in which principal fatty acids accounted as punicic (45.1%) in T. anguina and linoleic (30.1%) in S. mahagoni seed oils. Of the major energy producing nutrients, the seed samples contained large amounts of lipid (36.1% in T. anguina and 57.9% in S. mahagoni) and protein (20.9% in T. anguina and 13.0% in S. mahagoni) and potentially useful amounts of other nutrients. The knowledge from the nutritional analysis could be important to its appropriate industrial use and for improvement in the nutritional value. Assessment of the anti-microbial studies reported herein revealed the crude extracts of T. anguina and S. mahagoni seeds were not significantly inhibition against most of the tested bacteria and fungi. This study may lead to further ethno-pharmacognostic investigations to identify new compounds with therapeutic promise. KEY WORDS KEY WORDS KEY WORDS

A simple, high‐performance liquid chromatographic method is described for the separation of tetraenoic, trienoic and dienoic conjugated fatty acids on a Zorbax ODS reversed‐phase column using acetonitrile/tetrahydrofuran (95∶5, vol/vol) at a flow rate of 1.2 mL/min as mobile phase. Also described is the separation of the isomeric conjugated fatty acids with acetonitrile/water/tetrahydrofuran (90∶90∶1, by vol) as mobile phase. The simultaneous detection and identification of the separated geometrical isomers in the eluant was accomplished using photodiode array detection.
