中文摘要 | 松杉靈芝(Ganoderma tsugae Murrill)有四種商業形式,即成熟靈芝、靈芝茸、菌絲體和發酵濾液。冷水萃取物自此四種形式製備及其抗氧化性質經測定。成熟靈芝、靈芝茸和濾液之冷水萃取物顯現如低EC50值(<0.1毫克/毫升)所示之高抗氧力,而菌絲體之冷水萃取物則顯現0.34毫克/毫升之EC50值。關於還原力方面,靈芝之EC50值低於1毫克/毫升,而其餘之EC50值則為3.64-4.30毫克/毫升。靈芝茸顯現如4.66毫克/毫升之EC50值所示之有效1,1-二苯基-2-苦味基月井基團的清除能力,而其餘之EC50值則為10.14-11.72毫克/毫升。四種形式之松杉靈芝顯現如低EC50值(<0.1毫克/毫升)所示之高度有效羥基的清除能力。成熟靈芝和芝茸較菌絲體和發酵濾液在亞鐵離子之螯合能力上更有效。從所得之EC50值可知,冷水萃取物擁有良好的抗氧化性質,尤其是抗氧力和亞鐵離子之螯合能力。 |
英文摘要 | Ganoderma tsugae Murrill are available in the form of mature and baby Ling chih, mycelia and fermentation filtrate. From these four forms, cold water extracts were prepared and their antioxidant properties were studied. Cold water extracts from mature and baby Ling chih and filtrate showed high antioxidant activities as evidenced by low EC50 value (<0.1mg/mL) whereas that from mycelia showed a EC50 value of 0.34mg/mL. With regard to reducing power, the EC50 value for Ling chih was lower than 1mg/mL, whereas other EC50 values were 3.64–4.30mg/mL. Baby Ling chih was more effective in scavenging ability on 1, 1-diphenyl-2-picrylhydrazyl radicals as evidenced by its low EC50 value of 4.66mg/mL whereas other EC50 values were 10.14-11.72mg/mL. Four forms of G. tsugae were much more effective in scavenging ability on hydroxyl radials as evidenced by low EC50 value (<0.1mg/mL). Mature and baby Ling chih were more effective in chelating ability on ferrous ions than mycelia and filtrate. From EC50 values obtained, cold water extracts possessed good antioxidant properties, especially antioxidant activity and chelating ability on ferrous ions. |
