摘要

本研究旨在研究一种生长在阿尔及利亚西部撒哈拉沙漠地区的野生植物Herniaria fontanesii J. Gay。对从该植物地上部分提取的80%甲醇提取物的水溶液和丁醇组分进行了总酚和总黄酮含量的评价。采用体外清除1,1-二苯基-2-吡啶肼(DPPH)自由基和2,2 ' -氮基-双(3-乙基苯并噻唑-6-磺酸)(ABTS)自由基、铁还原力FRAP和钼还原力法评价其体外抗氧化活性。结果表明，该提取物具有较好的抗氧化活性，DPPH和ABTS测定的IC50分别为1.525±0.010 mg/ml和0.011±2.16610-5 mg/ml。将这些结果与在摩洛哥、突尼斯和阿尔及利亚的Laghouat收获的同一种植物的其他结果进行了比较。

Contribution to the valorization of Herniaria fontanesii J. Gay (Caryophyllaceae) grown in Septentrional Sahara and its antioxidant activity

This study aims to study a wild plant Herniaria fontanesii J. Gay which grows in Septentrional Sahara in El Oued Algeria. The evaluation of total phenolic and flavonoids content has been estimated in both aqueous and butanolic fractions of 80% methanolic extracts obtained from the plant's aerial part. Antioxidant activity was evaluated in vitro using scavenging assays of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and 2,2′-azino-bis (3- ethylbenzothiazoline-6-sulfonic acid) (ABTS) radicals, ferric reducing power FRAP and molybdenum reducing power methods. The extracts showed that the plant has a good antioxidant activity reaching to 1.525± 0.010 mg/ml for IC50 in DPPH assay and 0.011± 2.16610-5 mg/ml for IC50 in ABTS assay. A comparison has been done between these results and other results for the same plant harvested in Morocco, Tunisia and Laghouat, Algeria.
