2 理 葉 -- 猪 粒 葉 類 CNHN 行 93 年 年 瑩 理 林 理 理 (Morinda citrifolia) Rubiaceae Noni 療 料 葉 糖尿 療 療 葉 力 葉 精 LYD 猪 粒 力 力 類 粒 Morinda citrifolia Rubiaceae, commonly known as Noni, is a plant typically found in the Hawaiian, Tahitian and tropical Asia. The bark, stem, roots, leaves, and fruits have been used traditionally as a folk remedy for many diseases including diabetes, hypertension, and cancer. This study was to prove the leaves of Noni crude extracts in the protection ability of biological cell membrane which were attacted by oxidative damage. The results indicated that the absolute ethanol extracts of display significantly the inhibition ability of lipid peroxidation of microsomes from LYD pig liver. The scavenging mechanism of the absolute ethanol extracts of might have relation with hydroxyl radical. The antioxidant components might be attributed to higher content of polyphenolic compounds. Keywords: Morinda citrifolia, Noni, lipid peroxidation, microsomes. Free radical Reactive oxygen species 年來 理 糖尿 老 1 Morinda citrifolia Rubiaceae Noni
