I have a small amount of freeze plant material (less than 5 gr) and I want to extract essential oil from them. Is it possible to extract the essential oil in freeze plant material in -80 centigrade (salvia spp.)? My main problem is that when plant material transfer from -80 centigrade to room temperature, it will decompose and wet. I have to move my plant material from Iran to Italy and it takes 10 hours. can everyone tell me about the techniques for movement from -80 centigrade to room temperature and also Italy.
Thanks a lot
It can be done, but first you must bring the plant material at room temperature. The problem of the essential oils is that they have a low yield percentage when compared to the weight of the plant, for which, starting from a few grams you would get a very small amount of oil. Probably, since the low amount of plant material, it is better to proceed by extraction with non-polar (or low-polar) solvents (e.g. hexane, diethyl ether) instead of hydrodistillation to get the oil.
As said @ Dr Venditti you should bring plant material at room temperature for extraction of essential oil. For extraction you can proceed using Liken Nikerson apparatus, Clevenger apparatus, supercritical fluid extraction etc.

Well said robin.... Bring it at par to room temp. and select the preferred method.
