| 摘 要： | Gymnogongrus flabelliformis Hav. is a red alga belonging to Phyllophoraceae family (Gigartinales order), and widely distributed along the coast of China Sea1. Up to now no chemical constituent of this species has been reported. As a part of our program to assess systematically the chemical and biological diversity of seaweeds distributed in China Sea2-4, the red alga G. flabelliformis was collected along the coast of Qingdao, Shandong Province. We report herein the isolation and structural…

| Abstract: | Two new norisoprenoid derivatives have been isolated from the red alga Gymnogongrus flabelliformis. Their structures were elucidated as (3R, 6R, 7E)-( )-3-O-phenylacetyl-4,7-megas- tigmadiene-9-one and (3R,7E)-(?)-3-O-phenylacetyl-5,7-megastigmadiene-9-one, respectively, by spectroscopic methods including HRMS, 1D and 2D NMR techniques. |
