Table of Estimated Percentages

Compound	Estimated Percentage Range	Notes
Glycyrrhizin	2% to 25%	Major component, varies by species
Glabridin	0.1% to 0.5%	Higher in G. glabra
Liquiritin	1% to 5%	Significant in medicinal use
Isoliquiritigenin	0.1% to 1%	Minor, with pharmacological activity
Licochalcone A	1% to 5%	Abundant in G. inflata
18β-Glycyrrhetinic acid	Negligible (<0.01%)	Metabolite, not significant in raw roots
Licoricidin	0.02% to 0.72%	Species-dependent, higher in G. uralensis
Licochalcone C	Very small	Likely negligible, limited data
Isoliquiritin	0.1% to 2%	Minor flavonoid, anti-angiogenic
Liquiritigenin	0.1% to 1%	Related to liquiritin, minor component
