摘要：

Six novel marine natural products, dysidamides B [3] and C [5], three highly oxygenated sterols 9, 11, and 13, and a 1,4-dideoxyhexose 15 were isolated from the Red Sea sponge Dysidea herbacea, along with the previously known 24-methylene-5-alpha-cholest-7-ene-3-beta, 5, 6-beta-triol [7], furodysinin lactone, and alpha-D-xylopyranose. Structures of all new compounds were determined from spectroscopic data, especially extensive 1D and 2D nmr experiments.
