中文摘要 | 蓮是台南縣極具經濟價值之作物。蓮子心含各種生物鹼,在中醫上主要功能為去熱、鎮靜、降血壓等。蓮花含各種生物鹼、有機酸、氨基酸、及胡蘿蔔素,在中醫上主要功能為溫補腎、牌、及當作強心劑。本實驗主旨為利用試管內的分析,來探討蓮子心及蓮花的甲醇抽出物的抗氧化性。我們發現,蓮子心甲醇抽出物在抑制亞麻油酸的過氧化和質體DNA的氧化傷害方面,皆比蓮花的甲醇抽出物效果好。當分析其還原力與氫氧基、自由基的清除能力時,蓮子心與蓮花差異不大。然而只有蓮子心的甲醇抽出物具有亞鐵離子的螯合能力,因此金屬離子整合力的強弱可能正是影響蓮子心及蓮花抗氧化性強弱的原因。此外,以Amestest作安全性探討時發現,蓮子心及蓮花的甲醇抽出物,不論有無添加的mix在所測試之濃度 (0 - 2.5mg/plate) 內對Salmonella typhimurium TA 98和TA100皆沒有致突變性。 |
英文摘要 | Lotus (Nelumbo nucifera Gertn.) is a major economic aqueous plant in Tainan County. Lotus plumule contains various alkaloids and is used to remove “heat” or as tranquilizer and antihypertensive agent in folk medicine. Lotus blossom contains alkaloids, organic acids, amino acids, and -carotenoid and is used to “warm” kidney and spleen or used as a cardiotonic in folk medicine. In an attempt to assess the possible antioxidant activities of methanol extracts of lotus plumule and blossom, several in vitro assays were conducted. We found that both lotus plumule and blossom possessed strong reducing powers and free radical scavenging abilities. However, only methanol extract of lotus plumule exhibited ferrous ion chelating capabilities, which might contribute to the difference in antioxidant activities between lotus plumule and lotus blossom when analyzing the preventive effects on fatty acid peroxidation and plasmid DNA damage. No mutagenicity in the methanol extract of lotus plumule or blossom was found for Salmonella typhimurium TA98 and TA100, either in the presence or absence of S9 mix. |
