Abstract
臺灣山香圓 (Turpinia formosana Nakai) 為省沽油科(Staphyleaceae) 山香圓屬 (Turpinia) 之臺灣特有種植物,其為遍產於海拔1500 公尺以下闊葉林內之常綠喬木。本研究乃採集大量臺灣山香圓的葉部,以95% 酒精萃取並取其乾燥後粗萃物進行分配萃取,部分劃分後再以多種管柱層析方式加以進行成分分離,得到五個化合物。其中自乙酸乙酯層中得到一新的鞣花酸衍生物,經由理化及光譜數據分析鑑定其鞣花酸衍生物結構為3,3′-di-O-methylellagic acid-4-O-α-L-arabinofuranoside (1),為未發表過之新化合物。其餘四個化合物,經由理化及光譜相關數據分析以及文獻比對後,確認其四個化合物之結構為gentisic acid 5-O-β-D-(6’-O-galloyl)glucopyranoside (2),strictinin (3),casuarinin (4),及casuariin (5)。在活性評估部分,以自臺灣山香圓分離而得的五個化合物,利用人類造骨細胞 (human osteoblasts) 進行相關活性試驗:於MTT細胞存活率試驗中,發現3,3′-di-O-methylellagic acid-4-O-α-L-arabinofuranoside (1) 以及gentisic acid 5-O-β-D-(6’-O-galloyl)glucopyranoside (2) 細胞存活率> 80%;對促進鹼性磷酸酶表現之試驗中,發現3, 3′-di-O-methylellagic acid-4-O-α-L-arabinofuranoside (1) 有較顯著的促進效果;進一步在礦化染色試驗中,發現3,3′-di-O-methylellagic acid-4-O-α-L-arabinofuranoside (1)及gentisic acid 5-O-β-D-(6’-O-galloyl)glucopyranoside (2) 對於礦化染色表現均有顯著促進效果,有助於將來骨質新生方面之應用。
