THE STRUCTURE OF ARMILLARIZIN,A NEW PROTOILLUDANE SESQUITERPENOID AROMATIC ESTER FROM ARMILLARIA MELLEA(VAHL.EX FR)QUEL.

A new protoilludane sesquiterpenoid aromatic ester,named armillarizin (1)has been isolated from the artificially cultured mycelium of Armillaria me- llea(Vahl.ex Fr)Quel.(Tricholomataceae).Its structure was deduced on the ba- sis of spectral analyses.The relative configuration was established from the nuclear Overhauser effects and from the values of ~1H-~1H coupling constants.

原伊鲁烷型倍半萜醇芳香酸酯的碳谱研究

原伊鲁烷(Protoilludane)型倍半萜芳香酸酯类化合物是近十年来自人工发酵的真菌培养的菌丝中分离得到的一类新型天然产物。作者等自蜜环菌(Armillariamellea)菌丝体中分离得到17个该类型化合物,研究这些新化合物的化学结构,对其全去偶碳谱、偏共振谱或 INEPT 谱、^(13)C-~1HCOSY 谱和远程^(13)~1HCOSY 谱详细地进行分析研究,指出每个化合物各碳的归属,讨论了其碳谱的特征,将其应用于有关化合物的结构测定。
