Abstract
紅檜樹(Chamaecyparis formaosensis)是台灣原生種,生長在海拔1500–2150公尺的中央山脈區域。本篇研究材料為用甲醇萃取並減壓濃縮後之紅檜葉萃取物。使用液相層析與四級桿柱-飛行時間跟四級桿柱-離子阱兩種質譜,將紅檜葉的萃取物進行分析。利用上述兩種不同形式之質譜將紅檜葉萃取物中的成分進行鑑定。最後我們鑑定出了 22種成分,其中包含有黃酮類: catechin、quercetin-3-L-rhamnoside。雙黃酮類: hinokiflavone、7-O-methy hinokiflavone、amentoflavone、7-O-methyl-amentoflavone、4'-O-methyl-amentoflavone、4'-7-O-dimethy-amentoflavone。木質素: nortrachelogenin、thujastandin、cupressoside A。酚類: 2-Hydroxyaethyl-4- hydroxylbenzoate、p-coumaric acid、methyl 4-hydroxybenzoate。松香烷類: pisferal、pisferic acid、O-methyl pisferic acid、pisferol、3β- hydroxysugiol。桃拓烷類:
1-oxo-3β-hydroxytotarol、3β-hydroxytotarol。雙萜類: pisferanol。
