Five labdane diterpenoids, (3-5), zambesiacolactone A (7) and zambesiacolactone B (8), were isolated from the seeds of Aframomum zambesiacum (Baker) K. Schum., along with five known labdanes and a linear sesquiterpene, nerolidol. Their structures were elucidated by spectroscopic analysis. Their antiplasmodial activity was evaluated in vitro against Plasmodium falciparum. Compound 3 was the most active with an IC(50) value of 4.97 microM.
从赞比亚豆蔻(Aframomum zambesiacum (Baker) K. Schum.)的种子中分离出了5种半日花烷二萜(3 - 5)、赞比亚内酯A(7)和赞比亚内酯B(8),以及5种已知的半日花烷和一种直链倍半萜——橙花叔醇。通过光谱分析阐明了它们的结构。体外评估了它们对恶性疟原虫的抗疟活性。化合物3活性最强,IC50值为4.97微摩尔。
