    Abstract:
    Okra has different uses as a food and a remedy in traditional medicine. Since it produces many seeds, distribution of the plant is also quite easy. Although seed oil yield is low (4.7%), since the linoleic acid composition of the seed oil is quiet high (67.5%), it can still be used as a source of (UNSAT) unsaturated fatty acids. In this study, samples of okra grown in four different locations were analyzed to measure fatty acid and amino acid compositions. The content of the lipid extraction ranged from 4.34% to 4.52% on a dry weight basis. Quantitatively, the main okra fatty acids were palmitic acid (29.18-43.26%), linoleic acid (32.22-43.07%), linolenic acid (6.79-12.34%), stearic acid (6.36-7.73%), oleic acid (4.31-6.98%), arachidic acid (ND-3.48%), margaric acid (1.44-2.16%), pentadecylic acid (0.63-0.92%), and myristic acid (0.21-0.49%). Aspartic acid, proline, and glutamic acids were the main amino acids in okra pods, while cysteine and tyrosine were the minor amino acids. Statistical methods revealed how the fatty acid and amino acid contents in okra may be affected by the sampling location.
