Abstract

Echinacea purpurea (L.) Moench plants serve as a source of medicinal raw materials: fresh and dried aboveground parts and rhizomes with roots (Rhizomata cum radicibus). They contain total phenylpropanoids (formerly “oxycinnamic acids”, “hydroxycinnamic acids”) and their derivatives, which underlie the immunostimulatory effect of the preparations. Tincture is the most common preparation. Accumulation of total phenylpropanoid derivatives in Echinacea rhizomes with roots is the least studied aspect. The purpose of the present work is to study the effect of the timing and frequency of removal of the aboveground part on total phenylpropanoids in Echinacea rhizomes with roots collected from cultivated plants of different ages. Another aim was to determine total phenylpropanoids in the tincture prepared from raw material ground to various degrees. Echinacea purpurea rhizomes with roots harvested in Moscow in 2008–2010, at the end of the growing period of plants aged 2, 3, 4, 5, and 7 years, were studied. The shoots were cut down during the stem formation (by single and repeated mowing during the growing period), budding, and flowering stages. The intact raw material was used to provide control samples. In 2008–2009, the highest accumulation of phenylpropanoid derivatives in rhizomes with roots was observed in groups with both repeated and single shoot removals performed during the shoot development stage at all plant ages. The shoot removals during the budding and flowering stages resulted in a significant reduction in phenylpropanoids. During the regional drought in July and August 2010, the raw material samples in the group with repeated shoot removals demonstrated the lowest accumulation of phenylpropanoids. The samples in the group with single shoot removal during the shoot development stage showed greater phenylpropanoid accumulation compared with the repeated mowing group. The content of phenylpropanoids in raw material from 2–4-year-old plants, regardless of the period of shoot removal and the year of the experiment, was significantly higher than in the raw material from older plants. It is recommended to supplement the “Agro-recommendation for the cultivation of Echinacea purpurea” with the agricultural method of repeated mowing of the aboveground part in the phenological phase of shoot development when the plant is grown as a source of rhizomes with roots. No effect of the particle size of the ground raw material (from 0.25 to 1.0 mm) on total phenylpropanoids in the tincture has been revealed
