Abstract

Licorice is a perennial herbaceous plant with antioxidant, antimicrobial, antiviral, anti-inflammatory and anticoagulant properties, and Iran is one of the countries exporting its roots. In this study, the diversity of phytochemical traits among different Iranian licorice landraces cultivated in field conditions was investigated. Rhizomes of different populations were collected from different regions of Iran in 2019 and were planted in a randomized complete block design with 5 replications in the medicinal plants collection of Shahid Beheshti University. . The studied traits were glycyrrhizic acid, glabridin, liquiritigenin, liquiritin, rosmarinic acid, rutin, total phenol, flavonoids content and antioxidant activity. The highest content of glycyrrhizic acid (155.17 mg/g dry weight) and glabridin (19.46 mg/g dry weight) were observed in Kazerun and Ilam population, respectively. The population of Yasuj had the highest liquiritin (5.32 mg/g dry weight) and liquiritigenin (12.16 mg/g dry weight). A positive and significant correlation was observed between glabridin and liquiritin in 5%, but it had a significant negative correlation with IC50 in 5%. Based on the results of cluster analysis, 22 licorice populations were divided into five main groups. Factor analysis showed that the first four factors were able to explain 69.21% of the total variance. Overall, the findings of this study showed that licorice populations had unique phytochemical properties that can be used to design breeding programs and use them in the pharmaceutical industry.
