title: [Study on chemical constituents from Mycale parishi].
abstract: Three alkaloids have been isolated from Mycale parishi collected from Naozhou Island of Zhanjiang in China, their structure were identified as 1-(4-Hydroxy-5-hydroxymethyl-tetrahydro-furan-2-yl)-5-methyl-1H-pyrimidine- 2,4-dione(I), 1H-Pyrimidine-2,4-dione(II), Pentacosanoic acid (2-hydroxy-1-hydroxymethyl-heptadec-3-enyl)-amide(III), respectively on the basic of the spectral data of MS, 1H NMR, 13CNMR.
