从海葵Bunodosoma caissarum中分离得到一个新的四元嘌呤类化合物，经光谱分析和X-射线衍射法鉴定为3，9-dimethyl-6-methylimino-8-oxo-3，6，8，9-tetrahydropurine(Caissarone)，为盐酸盐。X-射线结构表明，外环氮显然是最富电子的中心，分子是平面的。
A new quaternary purine derivative isolated from the sea anemone Bunodosoma caissarum has been identified, by spectroscopic measurements and X-ray diffraction analysis, to be 3,9-dimethyl-6-methylimino-8-oxo-3,6,8,9-tetrahydropurine (caissarone) and isolated as the hydrochloride. The X-ray structures indicates that the exocyclic nitrogen is apparently the most electron-rich centre and that the molecule is planar.
