Abstract
香杉(Cunninghamia konishii Hayata)為杉科(Taxodiaceae)杉屬(Cunninghamia),為台灣特有種的常綠大喬木,主要產在中部以北海拔1300~2800公尺處之林中,木材為針葉樹一級木,是台灣木材最好的一種,大多供建築、枕木、造船及棺木等用途。
香杉的研究除了心材部位曾被研究外,目前為止相當少對於其他部位的研究,所以,本研究利用香杉葉部經由甲醇浸泡萃取,萃取液經減壓濃縮後,濃縮液經由水、乙酸乙酯、以及正丁醇做分配萃取。取乙酸乙酯層利用矽膠管住層析做初步的分離,之後再利用薄層層析法以及半製備的高效能液相層析等方法,分離純化到個24個化合物,其中包括7個aliphatic類,8個diterpenoid類,3個lignan類,3個biflavone類,1個flavone類,2個其他類,其中化合物CK12、CK13、 CK14、 CK15、CK24為新化合物
