Table 2. Cytotoxicity of the compounds isolated from EADs towards MCF-7 and MDA-MB-231 cells at 72 hours as reflected by IC₅₀ value as determined by MTT assay.

Compounds	MCF-7	MDA-MB-231
	IC50 (μg/mL)	IC50 (μg/mL)
1	>100	>100
2	>100	>100
3	>100	>100
4	36 ± 1.7 a	35 ± 1.3 a
5	>100	83 ± 2.1 a
6	>100	>100

Data are represented as IC₅₀ ± SD of three replicates from three independent tests.

^a indicates statistically significantly different from untreated control (P<0.05).
