目的 為了尋找抗腫瘤的活性成分。方法 利用溶劑法和色譜法對綠?？M行了研究。結(jié)果 分離得到5個核苷，經(jīng)波譜學解析鑒定為2-羥基嘌呤核苷(Ⅰ)，脫氧肌苷(Ⅱ)，1-甲基黃嘌呤核苷(Ⅲ)，脫氧鳥苷(Ⅳ)，脫氧核糖胸腺嘧啶(Ⅴ)。結(jié)論 Ⅲ為一新天然產(chǎn)物，其余均為海洋生物中首次發(fā)現(xiàn)。

Object To study the chemical constituents of sea anemone, Anthopleura stell Verrill.Methods The chemical constituents were isolated and purified by chromatographic methods and their structures elucidated by chemical evidences and spectra data.Results 5 nucleosides were obtained and identified from the ethanolic extract as 2-hydroxy purine (Ⅰ); deoxyinosine (Ⅱ); 1-methylxanthosine (Ⅲ); deoxyguanosine (Ⅳ), and deoxyribo-thymidine (Ⅴ).Conclusion Compound Ⅲ was a new natural product， while the others were found from sea anemone for the first time.
