За багаторічними дослідженнями ехінацеї пурпурової (Echinacea purpurea (L.) Moench,) сорту Зірка Миколи Вавилова та ехінацеї блідої (Echinacea pallida (Nutt.) Nutt.) сорту Красуня Прерій вперше розроблені й запатентовані методи визначення продуктивності рослин прегенеративного періоду онтогенезу. Методики засновані на регресійних моделях із високими коефіцієнтами детермінації, на підставі яких можна без пошкодження рослин провести оцінку продуктивності надземної частини та кореневої системи протягом веґетаційного періоду. Вихідними даними для розрахунків слугують показники довжини і ширини листковоїпластинки, їх кількість, а також сума температур вище 5 0С і кількість діб від сівби. On the basis of long-term researches of Purple Coneflower (Echinacea purpurea (L.) Moench) variety «Zirka Mykoly Vavylova» and Pale Coneflower (Echinacea pallida (Nutt.) variety «Krasunja Preriy» for the first time ever there were developed and patented the methods for determining the efficiency of plants in pregenesic period of ontogeny. The foundation of methodology was made on the studies of regression models with high coefficients of determination which allow to make the estimation of aerial parts and root system productivity for the whole growing season without damaging the plants. The input data for the calculation are the indicators of the length and width of the leaf blade, the amount and the sum of temperatures above + 5 ºC and the number of days from sowing.

Echinacea purpurea (L.) Moench is widely known for its medicinal properties, being one of the most used medicinal plants for its immunostimulant properties. Nevertheless, there is still scarce information on its cytotoxic activity. Thus, this study aims at evaluating the cytotoxicity and antimicrobial activity of several aqueous and organic extracts of the aerial parts of this plant and chemically characterizing the obtained extracts. The analysis was performed by HPLC–DAD–ESI/MS. Fifteen compounds were identified; of these, seven were phenolic acids and eight were flavonoids. Non-polar compounds were evaluated by GC/MS, with a total of sixty-four compounds identified, and the most abundant groups were the sterols, fatty acids and long-chain hydrocarbons. The highest antimicrobial activity was exhibited by the dichloromethane, ethyl acetate, and acetone extracts. Dichloromethane and n-hexane extracts showed the highest cytotoxic activity. Therefore, they were fractionated, and the obtained fractions were also assessed for their cytotoxicity. Notwithstanding, the cytotoxicity of the extracts was superior to that of the obtained fractions, evidencing a possible synergistic effect of different compounds in the whole extracts.

Different Origin

Medicinal vegetal products of Echinacea radix (roots) or Echinacea herba (aerial part) are included among the products with an imunistimulatory action, and depending on the active principles they belong to the products with fenil-propionic compounds and imunomodulatory polizaharides. The experience took place during 2004 and 2005, and as followed he fenology of Echinacea purpurea (L.) Moench with different origin received from several areas from Europe (8) and a population from Cluj, plants bred by seedlings. Among the species taken into study, in the experimental years studied, Echinacea purpurea (L.) Moench, in climatic conditions from Cluj - Napoca, the latest proved to be: Porrentry-Switzerland and Population of Cluj-România, representing value for precocity growing in breeding programs. Aerial parts had a major contribution to the total plants weight. It was noticed that, in each years studied, the species from Varşovia-Poland, Műnchen-Germany, Siena- Italy and Jena-Germany. Among the studied species, in the two years of the experience, there weren`t any major differences concerning the content of fenil-propionic and imunostimulatory polizaharides.
