TABLE 1.

Growth inhibition (GI) concentrations of safranal with 95% confidence interval (CI) in LNCaP and PC-3 cells 72 h after release from quiescence.

GI%	LNCaP (mM)	95% CI	PC-3 (mM)	95% CI
GI50	0.133 ± 0.034	0.049–0.217	0.109 ± 0.002	0.102–0.115
GI90	0.239 ± 0.025	0.177–0.301	0.317 ± 0.045	0.205–0.428

Quiescent LNCaP and PC-3 cells were re-activated and treated with various concentrations of safranal, and the rendered GI₅₀ and GI₉₀ with 95% confidence interval were determined using the SYBR Green assay. The GI values represent the mean ± SD of at least three independent experiments.
