从非洲药用植物血缘隐甲(Cryptolepis sanguinolenta(Lindl.)Schlechter(Periplocaceaa)，并根据波谱证据对其结构进行了鉴定。对已知人工产物隐喹多林的H-1和C-13核磁共振归属进行了修正。
Neocryptolepine and biscryptolapine, two new alkaloids, were isolated from the root bark extract of the African medicinal plant, Cryptolepis sanguinolenta (Lindl.) Schlechter (Periplocaceaa), and their structures elucidated on the basis of spectral evidence. The H-1 and C-13 NMR assignments of cryptoquindoline, a known artefact, were revised.
