摘要

Glycyrrhiza glabra L., commonly referred to as licorice, is a perennial herbaceous species within the Fabaceae family, has been traditionally utilized in Ayurvedic medicine for hundreds of years and also serves as a flavoring agent. The extract and its metabolites exhibit diverse therapeutic properties, including the ability to combat oxidative stress, bacterial and viral infections, and inflammation. Glycyrrhizin, a triterpenoid secondary metabolite, is the main active compound in licorice root and exists in the form of glycyrrhizic acid salts bound to potassium, calcium, and magnesium. Glycyrrhizin is extracted from the roots of the plant, which damages the whole plant. Tissue culture enables the large-scale propagation, multiplication, and preservation of Glycyrrhiza germplasm, while elicitation triggers a plant's response to stress, increasing secondary metabolite production. Elicitors are generally divided into two types: Abiotic and biotic elicitors. Abiotic elicitors encompass various factors, including chemical agents, physical stimuli, hormonal signals, internal signaling molecules, and gases such as nitric oxide and ethylene. On the other hand, biotic elicitors include biological substances like polysaccharides and pathogens. This review aims to comprehend how the elicitation technique improves the secondary metabolites production in in vitro grown Glycyrrhiza plants. Furthermore, under aseptically controlled conditions, the review also emphasizes the role of particular elicitors in relation to notable metabolites in culture medium.
