| Résumé : |
Range of environmental, genetic, and chemical variability of sweet woodruff growing wild in Poland was investigated. Effect of selected environmental and agrotechnical factors (plant shading, soil pH, term of planting, and method of herb harvesting) on plant development and accumulation of biologically active compounds was evaluated. Basic parameters of in vitro plant propagation were determined. Water and alcoholic herb extracts were compared in respect of the content of phenolic compounds and antioxidant activity. There were no distinct differences between the investigated populations in the content of nuclear DNA. Plants from Warmia and Mazury area were richer in coumarins than those from Lublin province. Herb of plants growing under shading (70% sunlight reduction) were characterised by highest content of coumarins, phenolic acids, and iridoids. Coumarin content was the highest in herb collected at the plant blooming stage. In the in vitro studies the best medium for shoot regeneration was MS medium without any growth regulators. Alcoholic extracts from herb were characterised by higher content of coumarins than water extracts. |
