The phytochemical contents and medicinal values of Dacroydes edulis and Raphia hookeri exudates were investigated. Phytochemical screening of the plant showed that they contain the presence of bioactive compounds comprising saponins (2.08-3.98 mg 100 g(-1)), alkaloids (0.28-0.49 mg 100 g(-1)), tannins (0.47-0.72 mg 100 g(-1)), flavonoids (0.26-0.39 mg 100 g(-1)), and phenolic compounds (0.01-0.05 mg 100 g(-1)). The carbohydrates, lipids and protein content were 77.42-78.90%, 2.02-4.185% and 16.63-18.38% respectively. The exudates are a good source of water soluble vitamins; ascorbic acid (7.04-26.40 mg 100 g(-1)), niacin (3.12-4.00 mg 100 g(-1)), riboflavin (0.14-0.54 mg 100 g(-1)) and thiamine (0.15-0.22 mg 100 g(-1)). Both plants exudates are good sources of minerals such as Ca, Mg, P, Fe, Zn, Cu and Mn while Cr and Co were trace. These results indicate that exudates can be potential sources of feedstock for the pharmaceutical industry.
对可食油桐和钩叶酒椰渗出物的植物化学成分及药用价值进行了研究。对这些植物进行的植物化学筛选表明，它们含有生物活性化合物，包括皂苷（2.08 - 3.98毫克/100克）、生物碱（0.28 - 0.49毫克/100克）、单宁（0.47 - 0.72毫克/100克）、黄酮类化合物（0.26 - 0.39毫克/100克）和酚类化合物（0.01 - 0.05毫克/100克）。碳水化合物、脂质和蛋白质含量分别为77.42 - 78.90%、2.02 - 4.185%和16.63 - 18.38%。渗出物是水溶性维生素的良好来源；抗坏血酸（7.04 - 26.40毫克/100克）、烟酸（3.12 - 4.00毫克/100克）、核黄素（0.14 - 0.54毫克/100克）和硫胺素（0.15 - 0.22毫克/100克）。两种植物的渗出物都是钙、镁、磷、铁、锌、铜和锰等矿物质的良好来源，而铬和钴含量微量。这些结果表明，渗出物可能是制药工业原料的潜在来源。
