Suitability of Hydroponically-Grown Rumex acetosa L. as Fresh-Cut Produce

Abstract

Sorrel (Rumex acetosa L.) is a perennial wild herb appreciated as a folk medicine and for use in folk-traditional cuisines, and its nutraceutical properties are increasingly known and studied. Nowadays, there is a lack of knowledge about the possibility of using this species as fresh-cut produce, and no reports have investigated the physiological/biochemical changes of sorrel leaves upon storage. To test the aforementioned, sorrel seedlings were cultivated in a floating system and two consecutive harvests took place: The first cut at 15 days (C1) and second cut at 30 days (C2) after sowing. Fresh-cut sorrel leaves from C1 and C2 were stored in plastic boxes at 4 • C for 15 days and chlorophylls, carotenoids, total phenols, flavonoids, ascorbic acid, and antioxidant capacity were evaluated during the storage period. During storage, sorrel leaves from the same cut did not show significant changes in total phenolic content and antioxidant capacity, which represents a positive outcome for the maintenance of the nutraceutical value of this species. For this reason, sorrel may be a very promising species as a "new" fresh-cut leafy vegetable. However, some differences were observed between the two cuts, especially in the total flavonoid and the total ascorbic acid contents. While promising, further research will be necessary to standardize the yield and the nutraceutical content of this species in different cuts, which will be necessary to introduce and promote sorrel to consumers.

“…Seven species of common Polygonaceae plants, including Fagopyrum dibotrys [ 10 , 13 , 14 ], Fallopia multiflora [ 40 , 41 ], Polygonum aviculare [ 42 , 43 , 44 ], Polygonum orientale [ 45 , 46 ], Reynoutria japonica [ 11 ], Rheum officinale [ 12 ], and Rumex acetosa [ 47 , 48 , 49 , 50 ] were kindly supplied by Bozhou Chinese herbal medicine market in Anhui province (Anhui, China) and identified by Prof. Z.S. Liang, Northwest A&F University.…”

Borago Officinalis L.: A Review Oon Extraction, Phytochemical, and Pharmacological Activities

“…The extraction of bioactive compounds from medicinal plants is a complex process involving several stages, from the selection of plant species to their characterization. Key factors, including the growth conditions of plant species, their maturation levels during harvest, the conservation conditions, and the harvest period significantly influence the bioactive compounds within plant species and, consequently, the composition and content of extracts [34,36–38] . In the subsequent sections, the impact of extractions techniques and their operational parameters, such as extraction time, solvent type, temperature, etc., are explored on the extraction of bioactive compounds.…”

“…Ceccanti et al. (2022) [36] investigated the influence of seasonal fluctuations and harvesting on polyphenol content and the DPPH scavenging activity in fresh and boiled B. officinalis leaves subjected to methanolic extraction. Higher values were observed in spring, with an increasing trend after each harvest, although a decrease was noted for boiled leaves.…”
