ABSTRACT

African walnut (P. conophora Mull. Arg.) root is used traditionally as antitussive and expectorant. The decoction and infusion of the root is often taking without any standard measurement, hence the need to investigate the proximate, sugar compositions and fatty acids content of its root bark with a view to establish its industrial and pharmacological importance. Proximate, sugar, and fatty acids were determined using standard methods as described by Association of Official Analytical Chemists. The proximate analysis showed that the root bark contained high amount of moisture (71.70 ± 0.01)%, followed by crude fiber (18.80 ± 0.01)% while protein and ash contents were (3.42 ± 0.01)%, and (2.84 ± 0.02)%, respectively, and crude fat was (1.34 ± 0.01)%. Sugar analysis revealed that the root contained sucrose (4.37 ± 0.02) %, glucose (3.28 ± 0.02) % and maltose (0.86 ± 0.02)%. The fatty acids analysis showed that the root bark contained saturated, mono unsaturated and poly unsaturated fatty acids. The prominent saturated fatty acid was stearic acid with the value of 4.10% while oleic acid (33.88%) was the highest for mono unsaturated fatty acid. Linolenic acid with the values of 35.57% was the prominent among the polyunsaturated fatty acids. The study has revealed the presence of some essential nutrients in the root bark of African walnut in moderate proportion which suggest the potential utilization of this plant part as nutrient, addictive, or supplement in drug and cosmetics formulation.

摘要

非洲胡桃 ( P. conophora仔细。Arg.) 根传统上用作镇咳和祛痰。根的煎煮和浸液通常在没有任何标准测量的情况下进行，因此需要调查其根皮的近似糖成分和脂肪酸含量，以确定其工业和药理学重要性。使用官方分析化学家协会描述的标准方法测定近似物、糖和脂肪酸。近似分析表明，根皮含水量较高（71.70±0.01）%，其次是粗纤维（18.80±0.01）%，而蛋白质和灰分含量分别为（3.42±0.01）%和（2.84±0.02）% , 和粗脂肪为 (1.34 ± 0.01)%。糖分分析显示，根含有蔗糖 (4.37 ± 0.02) %、葡萄糖 (3.28 ± 0.02) % 和麦芽糖 (0.86 ± 0.02)%。脂肪酸分析表明，根皮含有饱和、单不饱和和多不饱和脂肪酸。突出的饱和脂肪酸是硬脂酸，其值为4.10%，而油酸（33.88%）是单不饱和脂肪酸最高的。多不饱和脂肪酸中以亚麻酸含量为35.57%。该研究揭示了非洲胡桃根皮中某些必需营养素的含量适中，这表明该植物部分具有作为营养素、成瘾剂或药物和化妆品配方中的补充剂的潜在用途。88%) 是单不饱和脂肪酸最高的。多不饱和脂肪酸中以亚麻酸含量为35.57%。该研究揭示了非洲胡桃根皮中某些必需营养素的含量适中，这表明该植物部分具有作为营养素、成瘾剂或药物和化妆品配方中的补充剂的潜在用途。88%) 是单不饱和脂肪酸最高的。多不饱和脂肪酸中以亚麻酸含量为35.57%。该研究揭示了非洲胡桃根皮中某些必需营养素的含量适中，这表明该植物部分具有作为营养素、成瘾剂或药物和化妆品配方中的补充剂的潜在用途。
