Hi all.
Is there any way to find plants with enough extract-able EO during sampling in nature?
In my mind plant smell or taste is not enough (for example, walnut epicarp has a strong smell and taste but No EO), I need an expert for solve it!

BRR Rao and Sunil kumars views are more suitable. Almost all plants are bestowed with essential oil may be in varied quantities.
usually,
the aromatic plants gives a good yield of essential oils
they are rare, but exist, non aromatic plants with good yield of EO
the taste is not an indicator for EO.
other factors to considering, species, genus, family, climat, altitude, season...etc
Clevenger's apparatus is widely used for isolating essential oils from plant tissues. If facilities exist in your laboratory hydro-distil a sample of your plant material to check the presence and yield f the essential oil in the test plant.
Yes, odour is not proportional to yield of EO, so at filed it may be difficult to decide, by distillation in Clavenger's apparatus you will get an idea of the quantity of EO in %w/w of v/w.

Sometimes it may not be possible to isolate the EO using Clevenger trap as the compounds may be thermo-degradable for this reason some flowers like jasmine and tuberose are extracted with solvents to yield concentrates.
Thanks all for kind answers.
Actually i need some technique for finding E.O. containing plants in the field not in a lab.
it will be my pleasure if you kindly share your experiments in the field.
Extacting oil from plants is a techincal issue best performed in a laboratory using Clevenger's apparatus. However, there are plants that the fluid in their back when felt shows theh contain oil as the oil content in them get glued to the finger like grease.
Essential oils containing plant burned with aromatic flame. This is only identity of essential oils test
