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.
