摘要

Thymbra capitata (L.) Cav. cell suspension cultures were treated with different elicitors including β-cyclodextrins, separately or with methyl jasmonate, coronatine, (Z)-3-hexenol, and β-glucan, on phytosterol and phenolic compound production. The elicitation with 70.0 mM β-cyclodextrins in combination with coronatine or (Z)-3-hexenol induced the maximum accumulation levels of phytosterols in the extracellular medium at 168 h of treatment using a high cell density. Likewise, the levels of phenolic compounds were also enhanced in the presence of β-cyclodextrins being higher when they were used in combination with coronatine for 168 h. Therefore, the presence of β-cyclodextrins increased the accumulation of bioactive metabolites in the extracellular medium of T. capitata suspension cultured cells. This work sheds light on a biotechnological method to boost the accumulation of bioactive compounds in aromatic plants, which can be utilized in various industries such as food, pharmaceuticals, and cosmetics. By optimizing the elicitation process, this study provides a sustainable and efficient approach to produce valuable bioactive compounds, reducing the dependency on traditional extraction methods from field-grown plants.
