Three hundred and twenty-seven indigenous Iraqi plant species were screened for their antimicrobial activities and for the presence of alkaloids. The plants represent 221 genera and 49 families. Ethanolic extracts were tested for the presence of alkaloids with both Mayer's and Dragendorff's reagents. Of these, 146 species, belonging to 109 genera distributed among 32 families, showed positive alkaloid tests to both reagents. Of these, 26 genera have not been previously reported in the literature as containing alkaloid-bearing plants. The extracts were also tested for their in vitro antimicrobial activity by an agar dilution-streak method against six economically significant microbes. Five species were highly active, while another 90 species showed weak activity against one or more microorganisms.
对327种伊拉克本土植物物种进行了抗菌活性和生物碱存在情况的筛选。这些植物分属于221个属和49个科。用迈尔试剂和德拉根多夫试剂对乙醇提取物进行生物碱检测。其中，分布在32个科的109个属中的146个物种对两种试剂的生物碱检测均呈阳性。其中，有26个属此前在文献中未有含生物碱植物的报道。还通过琼脂稀释划线法对提取物针对六种具有经济意义的微生物进行了体外抗菌活性测试。5个物种具有高活性，另有90个物种对一种或多种微生物表现出弱活性。
