TABLE 2.

The selective index between non‐small cell lung cancer (NSCLC) and normal cells.

Cell line	Time	PA	Cisplatin	VCR
A549	24 h	1.47	0.78	1.05
	48 h	1.58	0.49	1.25
A549/V16	24 h	1.23	0.98	0.42
	48 h	1.33	0.90	0.22

Note: The selectivity index (SI) was calculated as the IC₅₀ value of the normal cell line divided by the IC₅₀ value of the NSCLC cell line. The higher the SI value, the greater the selectivity of the drug for NSCLC cells.

Abbreviations: PA, patchouli alcohol; VCR, vincristine.
