作者曾报道,从“Kannan Keihi”的桂皮(Cinna-momum cassia Blum)的水提取物中分得6个对抗补体有活性的二萜类成份。本文从称为“Toko Keihi”桂皮(同一种桂皮)的水抽提物经进一步的硅胶及Am-berlite XAD-2分离,结合乙酰化后分离纯化,除分得上述6个化合物外,还分得另外7个有抗补体活性的二萜类成分。特别对其中第7和第8二个新化合物进行了结构测定。 The authors have reported that six anti-complement active diterpenoid components were separated from the water extract of Cinna-momum cassia Blum in “Kannan Keihi”. This article from the water extract known as “Toko Keihi” cinnamon (the same cinnamon) water by further silica gel and Am-berlite XAD-2 separation, combined with acetylation separation and purification, in addition to the above six compounds, but also points Have another seven anti-complement activity of diterpene components. In particular, the 7th and the 8th novel compounds were structurally determined.
