Eleven flavonoids were isolated from the leaves of the halophyte Apocynum venetum. Among them, the isolation of plumbocatechin A (1), 8-O-methylretusin (2) and kaempferol 3-O-(6″-O-acetyl)-β-D-galactopyranoside (7) was reported for the first time from this plant. Their structures were identified by using spectral methods, including 2D NMR experiments, and confirmed by comparing with the literature data. In addition, the antifouling activities of these compounds against the marine fouling bacteria, Bacillus thuringiensis, Pseudoalteromonas elyakovii and Pseudomonas aeruginosa, have been evaluated in this article.
从盐生植物罗布麻叶中分离出了11种黄酮类化合物。其中,3,4,5-三羟基苯乙酸儿茶素A(1)、8-O-甲基异鼠李素(2)和山奈酚3-O-(6″-O-乙酰基)-β-D-吡喃半乳糖苷(7)首次从该植物中分离得到。通过光谱方法(包括二维核磁共振实验)鉴定了它们的结构,并与文献数据进行比较得以确认。此外,本文还评估了这些化合物对海洋污损细菌苏云金芽孢杆菌、埃氏假交替单胞菌和铜绿假单胞菌的防污活性。
