【 摘 要 】

Chemical investigation of the methanolic extract of the ascidian Didemnum psammatodes has led to the identification of the nucleosides 2'-deoxyuridine (1), thymidine (2), 2'-deoxyinosine (3) and 2'-deoxyguanosine (4), the steroids cholestanol, cholestanone and stigmasterol in mixture and batyl alcohol plus two analogs, 1-heptadecyloxy-2,3-propanediol and 1-nonadecyloxy-2,3-propanediol in mixture. Their structures were proposed by NMR, MS and comparison with literature data and GC-MS analysis.
