Abstract

The function components of Portulaca oleracea L. are abundant. This study compared the content of functional components, antioxidant activity, and tyrosinase inhibitory activity in different solvent extracts of Portulaca oleracea L, including methanol extracts and aqueous extracts. The ethyl acetate extract from the aqueous extract of Portulaca oleracea L. demonstrated the highest content of total phenols, total flavonoids, total saponins, chlorogenic acid, p-hydroxycinnamic acid, and ferulic acid, along with the best antioxidant and tyrosinase inhibitory activities. Moreover, a significant positive correlation was observed between the content of functional components and in vitro activities (p < 0.05). The findings indicated that the ethyl acetate extract from the aqueous extract of Portulaca oleracea L. was rich in functional components and exhibited the most potent biological activities, providing a theoretical basis for the development and utilization of this plant.

马齿苋功能成分含量及抑制黑色素活性的比较分析

马齿苋的功能成分丰富。本研究比较了马齿苋不同溶剂提取物（甲醇提取物和水提取物）的功能成分含量、抗氧化活性和酪氨酸酶抑制活性。马齿苋水提物中总酚、总黄酮、总皂苷、绿原酸、对羟基肉桂酸和阿魏酸含量最高，抗氧化活性和酪氨酸酶抑制活性最好。此外，功能成分含量与体外活性呈显著正相关(p <；0.05)。结果表明，马齿苋水提液中乙酸乙酯提取物具有丰富的功能成分，具有最有效的生物活性，为马齿苋的开发利用提供了理论依据。
