Cytotoxicity of the 70% EtOH extract of A. sieboldii roots and its solvent fractions in human ovarian cancer cells A2780 and SKOV3.

Extract or Fractions	IC50 (μg/mL) *
	Human Ovarian Cancer Cells
	A2780	SKOV3
70% EtOH extract	31.5 ± 16.83	>200
EtOAc fraction	19.89 ± 4.20	118.47 ± 19.78
Water fraction	107.20 ± 15.80	139.30 ± 29.13

* The IC₅₀ value is defined as being a concentration that lowers cell viability by 50%. The value shows an average of the results of three independent experiments having similar patterns.
