Abstract
薑科植物以月桃屬種類較多,其中台灣有26種,且14種為台灣原生種。而本研究採集8種台灣原生種之月桃屬植物葉部,分別以50%和95%的乙醇迴流萃取,並評估萃取物對數種癌和正常細胞株之毒性。其中以95%的山月桃萃取物對AGS, HeLa, HL-60和KB細胞株具有最強的抑制癌細胞生長,IC50分別為89.45、 76.82、29.92和 28.31 micro-g/mL。繼而比較山月桃之各部位活性,仍以葉部對各種癌細胞的抑制作用最強,且誘導HL-60凋亡,因此利用HL-60毒性追蹤分離山月桃葉部萃取物之抗癌活性成分。
首先以正己烷和水作溶解分離,而正己烷劃分部對HL-60及P-388D1細胞的IC50 均約為17.34 micro-g/mL,比水層作用強,並且連續九天注射100 mg/kg 於P-388D1之CDF1擔癌鼠腹腔後,能夠有意義地延長其生命(ILS%=15 %)。因此,再利用矽膠管柱分離正己烷劃分部,結果得到了intermedins A、B及coronarin E三個labdane型之雙萜類,其產率分別為0.043, 0.009, 0.005 %。Intermedins A及B是屬於新穎型的化合物結構,其中intermedin A抑制HL-60和P-388D1之生長作用,並誘導其進行凋亡。體內抗癌活性試驗顯示intermedin A在2及20 mg/kg劑量下對P-388D1之CDF1擔癌鼠顯示劑量依存性的體內抗癌效力。綜合結論,推測intermedin A新穎型雙萜化合物可能成為開發抗癌藥物的前導物質。
