“…Roseroot is characterized by high morphological, phytochemical, and genetic differentiation [16][17][18][19][20][21]. Our previous investigations showed biometric and phytochemical co-variability of this species.…”

“…In the next year, a decrease in the percentage share of rhizomes to 69% of the total weight of raw material was detected. This was due to the decay of the oldest, central parts of rhizomes and the division of them into many smaller pieces [18].…”

“…The length of the leaf lamina ranged from less than 1.5 to 5.0 cm, and the width from 0.5 to more than 1.5 cm. The raw material of roseroot originating from separate populations is characterized by high phytochemical variation [10,16,18,29]. The results obtained by Wiedenfeld et al [17] indicate that, besides the content of substances, also their composition can change in a broad range.…”

Roseroot (Rhodiola rosea L.) belongs to important herbs in folk medicine of Scandinavia, Russia, Mongolia, and China. Its therapeutic usage is mainly associated with the adaptogenic properties of this species. Roseroot is characterized by high morphological, phytochemical, and genetic differentiation. The aim of the present work was to determine the biometric and phytochemical co-variability of this taxon. Samples of Rh. rosea were collected from 4-year-old experimental field cultivation established by rhizome division in western Poland. For each plant, the biometric measurements of the clumps, shoots, leaves, and rhizomes with roots were carried out. In the underground plant parts (raw material), the contents of the main active compounds (phenylpropanoids, phenylethanoids, phenolic acids, and catechins) were determined by the HPLC-DAD method. K-means clustering analysis showed three well-separated plant groups of Rh. rosea that differed significantly in the level of most of the investigated components. It was interesting that in the raw material with a high content of phenylethanoids, a low level of phenylpropanoids was found, and vice versa. These chemical groups clearly differed in luxuriance of plants, too. The important diagnostic feature was also the degree of leaf serration. The morphological and phytochemical co-variability of roseroot was confirmed by the correlations detected between some active compounds (especially catechins and rosavin) and biometric traits describing the size and serration of leaves, the size of clumps and shoots as well as the weight of the raw material.

“…rosea rhizomes and roots [13]. The most important biologically active constituents are phenolics [14]. There are mainly: phenylpropanoids (rosavin, rosin and rosarin), phenyletanoids (salidroside and p-tyrosol), flavonoids, proanthocyanidins as well as tannins [15][16][17][18][19][20].…”

Biometric and phytochemical variability of roseroot (Rhodiola rosea L.) from field cultivation

S u m m a r y Roseroot (Rhodiola rosea L.) is an adaptogenic plant, widely used in the traditional medicine of Scandinavia, Russia, China and Mongolia. The aim of the study was to determine the biometric and phytochemical co-variability of this species under field cultivation in western Poland (Plewiska near Poznań). The plant material originated from four-year-old cultivation established twice by rhizome division in autumn 2007 and 2008. In the study, 46 individuals (23 plants in 2011 and in 2012) were used. The biometric analysis included measurements of the basic characteristics of plants related to the size (luxuriance) of clumps, shoots, leaves and rhizomes with roots (raw material). The amounts of total polyphenols (expressed as gallic acid), tannins (expressed as pyrogallol) and flavonoids (expressed as quercetin) were determined spectrophotometrically. The obtained results showed high variation of Rh . rosea, especially in the level of flavonoids (0.01-0.20% DM) and in the weight of raw material (113-1156 g FM/plant). There were observed correlations between the phytochemical (flavonoid and total phenolic content) and biometric (water content, leaf number, shoot and clump size) features.

“…R. rosea is growing very slowly (Ling-ling et al 2007; Mirmazloum et al 2014). The cultivation of this species aiming high levels of biologically active substances is quite long and takes between 5 to 7 years (Furmanowa et al 1999;Galambosi 2006) and very often the 21 biosynthesis of salidroside is in the low range, between 0.13-1.6 % DW (Furmanowa et al 1999;Linh et al, 2000;Platikanov and Evstatieva 2008), and that of rosavins is between 0.1-3.0% DW (Furmanowa et al 1999;Saunders et al 2013), frequently with high deviation in the content between different species or even intraspecially due to heterozygosis, morphological and chemical variability (Weglarz et al 2008;Mirmazloum and György 2012). Along with that, these substances are found in lower amounts in the field-cultivated R. rosea than the naturally growing plants (Ma et al 2008).…”
