Abstract
台灣五葉松為松科植物,喬木,主要分布在中央山脈海拔 300~ 2000
公尺之山區。在初步的生物活性評估中,台灣五葉松葉部粗抽物顯示出具
有良好的抑制基質金屬蛋白酶-2 及基質金屬蛋白酶-9 活性。因此,在本實
驗利用生物活性導向搭配管柱層析及製備型高壓液相層析進行成分分離,
從台灣五葉松葉部共分離出二十個化合物,包含三個新化合物(3)、(4)及
(20),兩個人工新化合物:(18)與(19)以及十五個已知化合物分別為Chrysin
(1)、Apigenin (2)、PML3、PML4、Kaempferol 3-O-(3', 6'-di-O-E-p-coumaroyl)-
β-D-glucopyranoside (5)、Stenopalustrosides C (6)、kaempferol 3-O-(5'-O-Zp-
coumaroyl)-α-L-arabinofuranoside (7) 、kaempferol 3-O-(5'-O-E-pcoumaroyl)-
α-L-arabinofuranoside (8)、kaempferol 3-O-(5'-O-E-feruloyl)-α-Larabinofuranoside
(9)、pinoresinol (10)、matairesinol (11)、7-hydroxycoumarin
(12)、loliolide (13)、benzeneacetic acid (14)及、3-acetoxylabda-8(20),13-diene-
15-oic acid (15) 、3- hydroxylabda-8(20),13-diene-15-oic acid (16) 、13-
labdadien-16, 15-olid-18-oic acid (17)、PML18、PML19 及P ML20 化合物的
結構利用光譜法進行鑑定並與文獻做比對。在HT1080 纖維肉瘤細胞中,
黃酮類化合物具有較好抑制基質金屬蛋白酶活性且不影響細胞的存活率。
研究結果顯示出從台灣五葉松分離出之化合物具有開發成為抗老化的潛
力。
