摘要

植物是人类饮食中最便宜和不可或缺的成分，为人体提供生长和发育所必需的营养物质(碳水化合物、蛋白质、脂肪、氨基酸、维生素)。因此，本研究旨在研究巴西五角星茎皮(PBSB)的近因成分和矿物组成。PBSB的水分含量为8.75%，干物质含量为91.25%，粗蛋白质含量为6.43%，粗纤维含量为41.03%，粗脂肪含量为5.70%，灰分含量为12.11%，碳水化合物含量为17.82 (g/100 g)，总还原糖含量为0.47%，能量含量为632.2 Kj/100g。矿物分析结果表明，PSSB中钙(73.84 mg/100g)含量丰富，其次是磷(41.55 mg/100g)、镁(32.56 mg/100g)、钠(28.11 mg/100g)、锌(17.56 mg/100g)、锰(10.88 mg/100g)、钾(9.47 mg/100g)和铜(2.33 mg/100g)。PBSB中矿物丰度顺序为Ca、磷、镁、钠、锌、锰、钾、铜。结论是PBSB的蛋白质、能量和某些矿物质(铜和钾)含量较低。

PROXIMATE AND MINERAL COMPOSITION OF Pentadiplandra brazzeana STEM BARK

Plants are the cheapest and indispensable constituents of human diets supplying the body nutrients (carbohydrates, protein, fats, amino acids, vitamins) necessary for growth and body development. Therefore, this work was designed to examine the proximate and mineral composition of Pentadiplandra brazzeana stem bark (PBSB). Proximate composition of PBSB revealed the presence of 8.75 % moisture, 91.25 % dry matter, 6.43 % crude protein, 41.03 % crude fibre, 5.70 % ether extract, 12.11 % ash, 17.82 (g/100 g) carbohydrates, 0.47 % total reducing sugar and 632.2 Kj/100g energy respectively. Results on mineral analysis shows that PSSB is abundant in calcium (73.84 mg/100g) followed by phosphorus (41.55 mg/100g), magnesium (32.56 mg/100g), sodium (28.11 mg/100g), zinc (17.56 mg/100g), manganese (10.88 mg/100g), potassium (9.47 mg/100g) and copper (2.33 mg/100g). In order of mineral abundance in PBSB Ca ˃ phosphorus ˃ magnesium ˃ sodium ˃ zinc ˃ manganese ˃ potassium ˃ copper. It was concluded that PBSB is low in protein, energy and some minerals (copper and potassium).
