Abstract
Oil was extracted from seeds of Coula edulis, Dacryodes edulis, Garcinia kola and Cola lepidota, using n-hexane, chloroform and a fraction of n-hexane and chloroform (1:1) as extracting solvents. The extraction was carried out at a temperature of 60oC. Using n- hexane as the extracting solvent, 42.5%, 40.1%, 24.63% and 35.73% were the yields of oil extracted from C. edulis, D. edulis, G. kola and C. lepidota respectively. Values recorded for chloroform-extracted oil were 28.7%, 25.4%, 10.83% and 21.93% respectively. Using a fraction of n-hexane and chloroform (1:1), the experimental seeds had percentage oil yield of 31.4, 27.92, 13.53 and 24.63 respectively. The results show that C. edulis and D. edulis had high oil content, when compared with G. kola and C. lepidota. These results suggest that n-hexane remains a veritable solvent for extraction of oil from seeds of tropical plants.
使用正己烷、氯仿以及正己烷和氯仿（1:1）的馏分作为萃取溶剂，从 Coula edulis、Dacryodes edulis、Garcinia kola 和 Cola lepidota 的种子中提取油脂。萃取温度为 60 摄氏度。使用正己烷作为萃取溶剂，从 C. edulis、D. edulis、G. kola 和 C. lepidota 提取的油的产量分别为 42.5%、40.1%、24.63% 和 35.73%。氯仿萃取油的记录值分别为 28.7%、25.4%、10.83% 和 21.93%。使用正己烷和氯仿（1:1）馏分，实验种子的出油率分别为 31.4%、27.92%、13.53% 和 24.63%。结果表明，与 G. kola 和 C. lepidota 相比，C. edulis 和 D. edulis 的含油量较高。这些结果表明，正己烷仍然是从热带植物种子中萃取油脂的有效溶剂。
