Abstract
The present study was undertaken for chemical profiling and evaluation of Vetiver (Vetiveria
zizanioides N.) essential oil of promising Sugandha variety from different samples of roots (sample
1, sample 2, sample 3 and sample 4). Commercially available VEO was obtained from St. Botanica
pharmacy store, Panchkula, Chandigarh which was ordered online. Sample 1, sample 2, sample 3
and sample 4 were harvested after 10 months, months, 18 months and 5 years of sowing. The EOs
used in the study, appeared as pale yellow viscous volatile liquids, obtained in 0.55, 0.50, 1.16 and
0.26 % yield from sample 1, sample 2, sample 3 and sample 4, respectively. The yield was highest
in the roots harvested after 12 months of sowing and lowest in roots which was harvested very late
approximately after 5 years. A significant variation was observed in chemical composition of these
VEOs. VO3 had more diversity and VO1 had lesser diversity. However, the chemical composition of
VO5 was totally different from the other studied oils. The antimicrobial activity of VEOs was studied
against various bacterial and fungal strains. VO3 showed higher antibacterial activity against K.
aeruginosa, X. axonopodis pv. cyamopsidis, S. aureus and VO1 showed higher antifungal activity
against F. oxysporum and M. grisea. Whereas, VO5 displayed least activity against tested strains.
