Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The aim of this study was to produce caffeic acid derivatives from adventitious root cultures of Echinacea purpurea, which are of high pharmaceutical value. The effects of both media optimization and replenishment strategies were adopted to achieve improved production of E. purpurea adventitious roots and caffeic acid derivatives. Of the different media strengths (0.25 MS, 0.5 MS, 0.75 MS and 1 MS) tested for the culturing of adventitious roots in 5 L bioreactors, 0.5 MS medium was found to be most suitable for the growth of adventitious roots. The optima accumulation of biomass (73.6 g L FW and 10.03 g L DW), phenolics (61.14 mg g DW) and flavonoids (38.30 mg g DW) were achieved in this medium. Furthermore, fed batch cultivations (media replenishment with 0.25 MS, 0.5 MS, 0.75 MS and 1 MS at the end of 2 and 3 weeks) to further enhance the production of adventitious root biomass and metabolites were also attempted. High adventitious root biomasses (83.1 g L FW and 15.30 g L DW) were achieved with feeding of the 0.5 MS medium at the end of 2 week. This led to slight decreases in the total production of phenolics and flavonoids; however, this feeding was responsible for increases in the accumulation of caftaric acid (5.76 mg g DW) and cichoric acid (26.12 mg g DW).
