Approximate Concentrations of Active Components of PMI5011

Active compound isolated from PMI5011	Approximate Concentration
*2′,4′-dihydroxy-4-methoxydihydrochalcone (DMC-2)	1.3 μg/ml
2′,4-dihydroxy-4′-methoxydihydrochalcone (DMC-1)	0.7 μg/ml
Davidigenin	0.5 μg/ml
6-demethoxycapillarisin	1.2 μg/ml
* Sakuranetin	2.6 μg/ml

^*DMC-2 and sakuranetin are quantified using standard curves of pure compounds, other compounds are approximated from standard curves of DMC-2 (DMC-1, davidigenin) and sakuranetin (6-demethoxycapillarisin) because compounds are not available.
