从胆木中分离得到一个新的吲哚生物碱paratunamideE(1)以及6个已知吲哚生物碱,paratunamideA(2),nauclealotideC(3),nauclealotideA(4),vincosamide(5),strictosamide(6),naucleamideF(7)。其中,化合物7是首次从该植物中分离得到,通过波谱学的方法确定了化合物的平面结构和相对构型。
From the aerial parts ofNauclea officinalis (Pierre ex Pitard) Merr. et Churl, one new indole alkaloid paratunamide E (1) has been isolated together with six known indole alkaloids, paratunamide A (2), nauclealotide C (3), nauclealotide A (4), vincosamide (5), strictosamide (6) and naucleamide F (7). Naucleamide F (7) was isolated from Nauclea officinalis for the first time. All of the seven compounds above were elucidated by spectroscopic methods including 1 D and 2 D NMR soectroscoDic analyses.
