摘 要: 由藜科植物盐穗木(Halostachys caspica C. A. Mey.)的地上部分分离出5个苯酚酸类化合物。通过理化性质和波谱数据分析,分别鉴定为:4-羟基-3-甲氧基苯甲酸(1)、4-羟基苯甲酸(2)、2-羟基苯甲酸(3)、 4-羟基-3,5-二甲氧基苯甲酸(4)和3,4-二羟基苯丙烯酸(5)。对上述苯酚酸类化合物的抗菌和抗氧化活性进行了评价,其中化合物5表现出较强的抗菌和抗氧化活性。研究结果为盐穗木苯酚酸类化合物作为抗菌和抗氧化剂的开发和利用,以及提升盐穗木作为饲料的利用价值提供了依据。
关 键 词: 植物学;藜科;盐穗木;苯酚酸类化合物;抗菌活性;抗氧化活性

Abstract: Five phenolic acids have been isolated from the aerial parts of Halostachys caspica C. A. Mey. (Chenopodiaceae) for the first time. By means of physicochemical and spectrometric analysis, they were identified as 4-hydroxy-3-methoxy benzoic acid (1), 4-hydroxy benzoic acid (2), 2-hydroxy benzoic acid (3), 4-hydroxy-3,5-dimethoxy benzoic acid (4), and 3,4-dihydroxy benzeneacrylic acid (5). All phenol acids were evaluated to show a broad spectrum of antimicrobial activity on test microorganisms including seven bacterial and one fungal species as well as pronounced antioxidant activity. Among them, 3,4-dihydroxy benzeneacrylic acid (5) was screened to have the strongest antimicrobial and antioxidant activities. The results suggested that the isolated phenolic acids could be used for future development of antimicrobial and antioxidant agents, and also provided additional data for supporting H. caspica utilized as forage.
