Medicinal plants, their fertilization and elicitors treatment with the aim of maximum production some active substance.
 ŠRÁMEK, Jan
Echinacea purpurea belongs to adaptogenic plants containig pharmacologically active compounds. The most important parts of the plants for medical use are roots, but also aboveground parts are processed. The plants were grown in triennial precise small-parcel experiment using acetylsalicylic acid as an in vivo elicitor to increase the content of bioactive substances. The contents of cichoric acid, caffeic acid, chlorogenic acid and caftaric acid were assayed in roots, tops and flowers. Repeated application elicitors on leaves were conducted with three different concentrations in fortnightly intervals. Ethanol extracts from the plant samples were analysed by high performance liquid chromatography. The effect of the elicitor on the content of bioactive substances was statistically significant. The optimal concentration of the elicitor considering the content of bioactive substances in roots is the middle one. The effect of elicitor is year-dependent.
