Table 1. The IC₅₀ of JCo extract and VP-16 in HCC and normal cells.

		JCo extract (μg/ml)			VP-16 (μg/ml)
Cell line	Tumor type	24 h	48 h	72 h	24 h	48 h	72 h
HCC cells
Mahlavu	Human HCC	64.9 ± 3.11,2	58.5 ± 2.31,2	59.4 ± 1.01,2	54.7 ± 7.0	5.5 ± 0.8	<6.25
HepG2	Human HCC	48.9 ± 1.51,2	42.3 ± 0.21,2	43.9 ± 2.61,2	>200	18.1 ± 2.8	<6.25
J5	Human HCC	74.2 ± 3.61,2	67.2 ± 2.01,2	53.2 ± 31,2	>200	14.1 ± 0.9	7.3 ± 2.7
Normal cells
MDCK	Canis kidney epithelial cell	>87.7	>87.7	84.0 ± 0.6	>50	25.7 ± 2.7	2.7 ± 0.2
SEVC	Mouse vascular endothelia cell	78.8 ± 0.4	67.4 ± 0.4	66.8 ± 0.05	21.7 ± 4.9	1.9 ± 0.06	1.8 ± 0.1

Values are reported as mean ± SD (μg/ml). It was significantly different that compared HCC cells with MDCK (1) or SVEC (2) in JCo extract treatment at the same time points (P<0.05).
