摘要

本文主要研究了阿尔及利亚产梅丽莎(Melissa officinalis L.)水甲醇提取物的化学成分和抗氧化活性。液相色谱-质谱分析鉴定出6种化合物:咖啡酸、咖啡酸、羟基茉莉酸葡萄糖苷、咖啡酸葡萄糖苷、迷迭香酸和sageric酸。采用自由基清除率(DPPH)、自由基清除率(ABTS)、铜还原抗氧化能力(CUPRAC)和铁还原力(fe) 4种方法评价其体外抗氧化活性。与合成抗氧化剂相比，该提取物具有较强的抗氧化活性。DPPH法和ABTS法对自由基的清除活性最高，IC50分别为20.53±2.64 μg/mL和22.50±0.67 μg/mL。这些结果表明，梅莉莎可被认为是一种潜在的天然抗氧化剂来源，具有潜在的农业化学和制药工业的兴趣。

LC-MS Analysis and Antioxidant Activity of the Hydro-alcoholic Extract of Melissa Officinalis L. From Algeria

The present work focuses on evaluation of the chemical composition and antioxidant activity of the hydro-methanolic extract of Melissa officinalis L. from Algeria. The liquid chromatography-mass spectrometry analysis allowed the identification of six compounds: caffeic acid, caftaric acid, hydroxyjasmonic acid glucoside, caftaric acid glucoside, rosmarinic acid and sagerinic acid. The in-vitro antioxidant activity of the hydro-methanolic extract was evaluated by using four different methods including: radical scavenging assay (DPPH), scavenging activity (ABTS), cupric reducing antioxidant capacity (CUPRAC), and ferric reducing power assay. The extract exhibited a relatively strong antioxidant activity compared to the synthetic antioxidants. The highest radical scavenging activity was registered using DPPH and ABTS methods, IC50= 20.53±2.64 μg/mL and 22.50±0.67 μg/mL, respectively. These results suggest that Melissa officinalis L. could be considered a potential source of natural antioxidants with potential interest in the agrochemical and pharmaceutical industries.
