Abstract
許多薑科植物及其成分已被報導指出具有諸多生理活性,如抗癌、抗菌以及抗發炎等。在東南亞,紅球薑(Zingiber zerumbet Smith)被當作藥用植物或食物香料之用,故頗具開發之潛力。本研究利用層析法分離紅球薑之根莖部,得到zerumbone、3-O-methyl-kaempferol、kaempferol-3-O-(2,4-O-diacetyl-α-L-rhamnopyranoside)及kaempferol-3- O-(3,4-O-diacetyl-α-L-rhamnopyranoside)。接著分析紅球薑不同生長時期之水分及成分含量,發現栽種時間越久,主成分zerumbone含量越高且水分含量越少。而栽種後第5個月zerumbone含量驟升,因此我們認為紅球薑種植5個月後為最經濟的採收時節。抗發炎評估試驗方面,首先利用LPS誘導RAW264.7巨噬細胞抗發炎模式篩選分離得到之紅球薑成分,發現zerumbone及3-O-methyl-kaempferol具有抑制NO產生,其IC50值分別為4.37及 24.35 μM,且抑制iNOS及COX-2蛋白表現。上述結果顯示:zerumbone抗發炎能力較明顯,因此探討其作用機轉。結果發現zerumbone可刺激HO-1表現且呈現劑量依存性,當加入HO-1抑制劑時zerumbone抑制NO效果則明現下降,表示zerumbone可藉由刺激HO-1表現而抑制iNOS及NO產生。鹿角菜膠誘導小鼠足掌發炎試驗發現,zerumbone (10 mg/kg)於誘導前1小時口服給予,可顯著抑制小鼠足掌發炎腫脹。再利用輻射熱源引發大鼠痛閥與醋酸誘導小鼠疼痛扭體試驗評估zerumbone的鎮痛效果。結果顯示:zerumbone對大鼠輻射熱源並無顯著之延遲痛閥效果;zerumbone於低劑量下顯示些微抑制扭體次數,而在50 mg/kg劑量之下則明顯有止痛之效用。本論文證實,紅球薑之主要成分zerumbone具有消炎、止痛之活性。
