Dependence of the Concentration of Bioactive Compounds in Origanum vulgare on Chemical Properties of the Soil

Abstract

The aim of this study was to determine the dependence of the total phenolic, flavonoid, and extractive content in extracts of Origanum vulgare L. on the soil pH, humus, total nitrogen (Ntotal), and plant-available/mobile phosphorus (P2O5), as well as potassium (K2O), total calcium (Ca), magnesium (Mg), and sodium (Na) concentrations. Experimental fields were formed in four locations in Lithuania. Soil and perennial O. vulgare samples were taken at three sites of each experimental field. A total of 12 samples of soil and 12 samples of the tested plant were collected and analyzed. The concentrations of bioactive compounds in plants are significantly (p < 0.05–0.01) affected by some chemical properties of the soil: the total phenolic content was reliably correlated with the soil pH, Ntotal, Ca, Mg, and P2O5; the flavonoid content was correlated with the soil P2O5, K2O, Mg, and Na; and the extractive content was correlated with the soil humus, Ntotal, and Na. The obtained results are useful for the development of the commercial cultivation of O. vulgare.

Soil physicochemical properties associated with the yield and phytochemical composition of the edible halophyte Crithmum maritimum

“…However, the increase in phenolics can be influenced by different soil factors, such as pH or mineral elements, depending on the plant species (e.g. Klimienė et al, 2021). Our results suggest that C. maritimum seeds display higher content of chlorogenic isomers in soils with lower clay content and higher pH and Fe concentration, which is a useful insight for commercial cultivation since these metabolites are highly appreciated in nutraceutical industry, because of their biological properties, including antibacterial, anti-inflammatory and antioxidant characteristics (Liang and Kitts, 2016).…”

Green manure (Crotalaria juncea L.) enhances Origanum vulgare L. biomass accumulation, essential oil yield, and phytochemical properties

“…The availability of nutrients should be taken into account in the cultivation of medicinal plants because in addition to influencing primary metabolism, nutrient availability can alter the production of secondary metabolites (Gobbo-Neto & Lopes 2007). Studies with O. vulgare L. have already shown that the concentrations of bioactive compounds in plants are significantly affected by some chemical properties of the soil (pH, N, Ca, P, and Mg) (Klimienė et al 2021).…”
