摘要：

The determination of chemical structures of five novel compounds, i.e. one multibranched polyunsaturated fatty acid ((2E,4E,7S,8E,10E,12E,14S)-7,9,13,17-tetramethyl-7,14-dihydroxy-2,4,8,10,12,16-octadecahexaenoic acid) and its four glycosides from seven different myxomycetes is described. The absolute configuration of both hydroxyl groups was determined. The glycosides containing glucose, mannose and rhamnose. These compounds were identified by means of H-1 and C-13 NMR, MS, UV and IR spectra. Three of them were identified in Arcyria cinerea (Bull.) Pers., two in A. denudata (L.) Wetts., and A. nutans (Bull.) Grev., Fuligo septica (L.) Wigg., Lycogala epidendrum (L.) Fries, Physarum polycephalum Schwein., and Trichia varia Pers. contained one of the identified glycosides each. (C) 2002 Elsevier Science Ltd. All rights reserved.
