Inhibitory effects of borneol and camphor from Artemisia princeps var. orientalis essential oil against norovirus surrogates, FCV-F9 and MNV-1

Norovirus surrogates	Plaque formation (%)
Norovirus surrogates	DMSO 0.1% (v/v)	2TU	Borneol 5 mM	Camphor 25 mM
FCV-F9	100.00 ± 2.53^a	80.96 ± 8.38^b	102.17 ± 13.57^a	96.32 ± 4.63^a
MNV-1	100.00 ± 1.15^a	73.45 ± 5.16^b	95.12 ± 2.52^a	105.55 ± 1.73^a

Data were expressed as the mean ± SD using triplicates. Plaque formation % for the pretreatment of the virus with borneol or camphor was calculated as relative plaque formation using DMSO untreated control. 2TU (200 μM for FCV-F9 and 50 μM for MNV-1) was used as the positive control
