从两个不同的塔斯马尼亚海鞘植物中分离到5个新的过氢吡罗[2,1-j]喹啉-7- 1生物碱。这些化合物，圆柱胞嘧啶C-G，在结构上与先前从同一种海鞘中获得的圆柱胞嘧啶A密切相关。圆柱菌F和G是硫氰酸酯，最早从海鞘中发现。采用H-1核磁共振、C-13核磁共振、高分辨率质谱、化学相互转化等方法对新生物碱进行了鉴定。
Five novel perhydropyrrolo[2,1-j]quinolin-7-one alkaloids have been isolated from two different Tasmanian collections of the ascidian Clavelina cylindrica. The compounds, cylindricines C-G, are closely related in structure to cylindricine A which has been obtained previously from the same ascidian. Cylindricines F and G are thiocyanates, the first known from an ascidian. The identification of the new alkaloids was by H-1 n.m.r. and C-13 n.m.r. spectroscopy, high-resolution e.i. mass spectrometry, and chemical interconversions.
