SD = Standard deviation; according to Tukey’s test (), mean values in a column that are followed by the same letter do not substantially differ from each other. (HCPNO = H. coronarium essential oil from G.B.P.U.A. & T., Pantnagar, HCBO = H. coronarium essential oil from Chandika, Bageshwar, HCNO = H. coronarium essential oil from Dogaon, Nainital, HCPO = H. coronarium essential oil from MES colony, Pithoragarh).
