摘要
We examined the chemical constitution of the red alga Laurencia saitoi Perestenko,collected from Katsuura,Boso Peninsula,Chiba Prefecture,Japan.This specimen produced a new polyhalogenated acetogenin,named katsuural-lene(1),which structure was determined by the spectral methods,along with known diterpene,deoxyparguerol(2)and triterpene,thyrsiferol(3).In this paper we describe the structural elucidation of katsuurallene together with some biological activities.
