We wish to ascertain if it is better to dry onion bulbs before extraction or to extract by blending for antimicrobial studies.
Hydrodistillation using a Clevenger apparatus to obtain onion essential oil
I think the use of fresh onion bulbs is the best material to extract maximum number antimicrobial compounds for study. On drying, onion bulbs may loose some of the volatile compounds which are likely be antimicrobial in nature.
