摘要

白柳和紫柳属中草药，常用于制药行业。本研究对这两种树皮的乙醇提取物进行了植物化学和抗菌分析。采用薄层色谱法对水杨酸和水杨酸进行定性和定量植物化学分析；采用高效液相色谱法测定水杨酸的含量。树皮提取物对白柳产生4.300μg/ml-1的水杨酸，对紫柳产生1.167μg/ml-1的水杨酸。植物提取物在革兰氏阴性菌和阳性菌（大肠杆菌和金黄色葡萄球菌）上进行了检测。两种测试菌株都表现出轻微的耐药性，但金黄色葡萄球菌对所有提取物样品的抑制作用略高。

SALICIN CONTENT FROM SALIX ALBA L. AND SALIX PURPUREA L. EXTRACTS AND ITS ANTIBACTERIAL EFFECTS

The species Salix alba L. and Salix purpurea L. are medicinal herbs, frequently used in the pharmaceutical industry. This study performs phytochemical and antibacterial analysis of ethanolic extracts from the bark of these two species. The qualitative and quantitative phytochemical analyses were performed by thin-layer chromatography identifying the salicin and salicylic acid; the salicin content was assessed by high performance liquid chromatography. The bark extracts yielded 4.300 μg/ml-1 salicin for Salix alba and 1.167 μg/ml-1 salicin for Salix purpurea. The plant extracts were tested on Gram negative and positive bacteria (Escherichia coli and Staphylococcus aureus). Both tested strains showed a mild resistance, but S. aureus showed slightly higher inhibition by all extract samples.

期刊介绍： Contributii Botanice is an international, peer-reviewed journal publishing scientifically sound papers in the fields of Plant Systematics, Phytosociology, Plant Physiology and Morphology, Plant Ecology, Population Ecology, Ecosystem Ecology, Phytogeography, Phytopathology, Microbiology, Paleobotany, Plant Conservation and Cell/Molecular Plant Biology. Papers of mostly taxonomic nature or focussed on floristics and phytosociology will only be considered if they exceed the pure descriptive approach and have relevance interpreting patterns in the above mentioned plant sciences.
