研究了角果藜(Ceratocarpus arenarius)、盐穗木(Halostachys caspica)、里海盐爪爪(Kalidium caspicum)、叉毛蓬(Petrosimonia sibirica)、盐角草(Salicornia europaea)和小叶碱蓬(Suaeda microphylla)等六种新疆藜科植物提取物及其不同极性萃取部分对根癌土壤杆菌(Agrobacterium tumefaciens)、黄瓜角斑病菌(Pseudomonas lachry-mans)、番茄疮痂病菌(Xanthomonas vesicatoria)等植物病原细菌以及杨树溃疡病菌(Botryosphaeria dothidea)、棉花枯萎病菌(Fusarium oxysporumf.sp.vasinfectum)、稻纹枯病菌(Rhizoctonia solani)等病原真菌的抑制活性。结果显示角果藜、叉毛蓬和盐角草乙醇粗提物表现出一定抗细菌活性,其中以叉毛蓬和盐角草提取物对黄瓜角斑病菌的抑制活性最强。多数植物提取物及其不同极性萃取部分对杨树溃疡病菌表现出强的抑制活性。抗真菌活性成分主要存在于供试植物的石油醚、氯仿和正丁醇萃取部分中,提示活性成分为极性中等的化合物。角果藜和盐角草乙醇粗提物及其不同极性萃取部分对供试真菌有较好的抑制活性。
The effects of Ceratocarpus arenarius, Halostachys caspica, Kalidium caspicum, Petrosimonia sibirica, Salicornia europaea and Suaeda microphylla were studied. And other six kinds of Xinjiang Chenopodiaceae plant extracts and their different polarity extraction of Agrobacterium tumefaciens, Cucumber leaf spot pathogens (Pseudomonas lachry-mans), the pathogen of tomato pathogens (Xanthomonas vesicatoria) and other plant pathogens and Yang Botryosphaeria dothidea, Fusarium oxysporumf.sp. vasinfectum, Rhizoctonia solani and other pathogenic fungi. The results showed that the extracts of Coriolus versicolor, Fork Fritillaria and Salicornia Ethanol showed some antibacterial activities, of which the extract from Fritillaria ussuriensis and Scutellariae barbata had the strongest inhibitory activity against X. perturium. Most plant extracts and their different polarity extraction part of poplar canker bacteria showed strong inhibitory activity. Antifungal active ingredients are mainly present in the petroleum ether, chloroform and n-butanol extracts of the tested plants, suggesting that the active ingredient is a moderately polar compound. Quinoa and Salina grass ethanol extract and its different polarity extraction of the tested fungi have good inhibitory activity.
