Effect of jasmonic acid and yeast extract elicitation on low-molecular antioxidants and antioxidant activity of marjoram (Origanum majorana L.)

Abstract

Marjoram (Origanum majorana L.), commonly known as sweet marjoram, is a plant from the Lamiaceae family, which is cultivated mainly for its aromatic leaves used for culinary purposes (Prerna and Vasudeva, 2015). This herb has been traditionally used, especially in India, for thousands of years for the treatment of gastrointestinal disturbances, cough, and bronchial diseases (Saxena et al., 2016 ABSTRACTBackground. Elicitation, which is a way of inducing plant secondary metabolism, may be an effective method for improving the quality of plant food. The aim of this study was to determine how the application of jasmonic acid (as an abiotic elicitor) and yeast extract (as a biotic elicitor) influences the production of some bioactive compounds in marjoram and the antioxidant activity of this herb. Material and methods. Elicitation with 0.01 µM and 1 µM jasmonic acid as well as 0.1% and 1% yeast extracts was used for improving the health-benefiting quality of marjoram. The study focused on the effects of eliciting the level of some phytochemicals and the antioxidant activity of marjoram.Results. There were no significant differences in total phenolic content between the elicited and control plants. In turn, the elicitation with 0.1% and 1% yeast extracts caused 1.8-and 2.5-fold increases in the ascorbic acid content in marjoram leaves, respectively. Both biotic and abiotic elicitation resulted in elevation of chlorophyll content, but only the abiotic elicitor (jasmonic acid) caused a significant increase (by over 50%) in the carotenoid content of marjoram leaves. The antiradical activity of marjoram was increased by the abiotic and biotic elicitation, whereas only the abiotic elicitation resulted in improving the reducing power of this herb. Conclusions. In conclusion, biotic and abiotic elicitation could be an effective strategy for improving the level of some phytochemicals, as well as the antioxidant activity of marjoram. A particularly valuable finding obtained in this study is that natural elicitors e.g. yeast extract can be equally effective in elevating the content of some bioactive compounds in herbs e.g. marjoram as an abiotic one.

Antioxidative and Potentially Anti-inflammatory Activity of Phenolics from Lovage Leaves Levisticum officinale Koch Elicited with Jasmonic Acid and Yeast Extract

“…A majority of research on the use of yeast extract as a biotic elicitor reported in the literature was conducted in suspension cell cultures, and only a few reports present the effect of YE application to plants in vivo. In the research conducted by Złotek [16], elicitation with YE, as in the present study, did not increase the content of phenolic compounds but significantly increased the content of ascorbic acid and chlorophyll in marjoram leaves. Additionally, another biotic elicitor, chitosan oligosaccharide, was an effective stimulator of polyphenol production by oregano plants [25].…”

“…As indicated in our study, the antiradical and reducing potential of lovage extracts was evaluated mostly by JA elicitation (especially JA2), while the ability to chelate iron ions increased the most after the YE2 elicitation (Figure 1). Similarly, in studies on marjoram and basil elicitation, the use of jasmonic acid resulted in an increase in antiradical properties (marjoram and basil) and reducing power (marjoram) of this herb [16,21], as well as improvement of DPPH-free radical scavenging activity of the sweet basil after 0.1 and 0.5 mM methyl jasmonate treatments [8].…”

“…Biotic elicitors like yeast extract can substitute for fungal elicitors during a pathogen attack [12,13,14]. There are only few examples of yeast extract used to enhance the production of phytochemicals in whole plants [15,16].…”

Ozonation as a Method of Abiotic Elicitation Improving the Health-Promoting Properties of Plant Products—A Review

“…Studies on the elicitation of herbs are also being conducted. Złotek et al [51] studied the effect of elicitors on Origanum majorana L. According to their results, jasmonic acid elicitation significantly increased the carotenoid content and yeast extract increased the antioxidant content. Foliar application of methyl jasmonate and salicylic acid increased (2-fold) the concentration of folic acid in coriander foliage, and folates demonstrated higher stability during processing and storage [52].…”
