A Survey of Sesquiterpenoids from Marine Sponges,imal kingdom. Almost fifty new sesquiterpenoids from marine sponges have now been isolated and characterized. In this paper I will present a broad survey of these compounds, which can be subdivided into three main groups: (a) furan sesquiterpenes, (b) sesquiterpenoid hydroquinones, and (c) sesquiterpenoid isonitriles.作者: fertilizer 時(shí)間: 2025-3-22 20:07 作者: 使熄滅 時(shí)間: 2025-3-23 00:09
