Biometric features and content of phenolic compounds of roseroot (Rhodiola rosea L.)

Abstract

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.

Natural Deep Eutectic Solvents for the Extraction of Phenyletanes and Phenylpropanoids of Rhodiola rosea L.

“…The place of plant collection, vegetative phase, drying conditions, and other factors affect the content of active compounds. However, we have mentioned that the contents of rosavin and salidroside recovered by NADES were much higher than what was obtained using the other various methods, e.g., 4.11 and 0.93 [54], 3.68 and 1.62 [55], 3.61 and 3.79 [56], 3.50-2.70 [21], 9.77 and 1.81 [57], and 4.20 and 1.20 [58], respectively; all the amounts are given in mg/g. The rosin content in NADES extract was also higher compared to 0.53 mg/g [54], 0.80 mg/g [21].…”

Variability of Major Phenyletanes and Phenylpropanoids in 16-Year-Old Rhodiola rosea L. Clones in Norway

“…HPLC is a widely used technique for quantifying salidroside, tyrosol, rosavin, rosin, and cinnamyl alcohol in R. rosea [ 22 , 23 , 26 , 34 , 35 ]. HPLC analyses showed the high content and large diversity in the concentration of phenyletanes and phenylpropanoids in the R. rosea clones collected in 2017 ( Table 1 ).…”

“…The bioactive compounds’ variability in R. rosea , between years, was reported from two to three, four to five, four to seven, and four to nine years [ 14 , 35 , 46 , 55 ]. To our knowledge, this is the first study that investigated the variability of active compounds in R. rosea from three to twelve years.…”

The effect of bioactive components of plant origin on the physicochemical and sensory characteristics of functional sausages

“…The increase of sausage yellowness, however, is usually caused by lower antioxidative efficiency (Sebranek et al, 2005). On this case, it could be triggered by the presence of catechins in roseroot for example (Adamczyk et al, 2016;Wagh, et al, 2015).…”

“…Similar observations were noted for the finished products. This could be a result of the presence of polyphenols from galangal (Cheah & Abu-Hasim, 2000), maca (Sandoval et al, 2002), guarana (Basile et al, 2005), roseroot (Adamczyk et al, 2016) and honey (Pyrzynska & Biesaga, 2009).…”
