She joined the faculty at Beloit College in 1991. Her current research interests are in medicinal chemistry and chemical education.''


'''''Workshop Overview'''''

Essential oils have been used throughout human societies for as long as documentation exists. These oils were originally used for their aromatic quality as parts of ceremonial or religious events and evolved as a means of treating both physical and mental illness. Essential oils have been of interest to chemist for many years. These oils represent a diverse class of organic molecules that can be used to teach many aspects of organic chemistry, analytical methods, as well as many areas within the liberal arts. In this workshop you will be presented with the following:

1) '''Isolation techniques'''
*Steam distillation 
*Clevenger distillation (file:///Users/besturgeon/Downloads/Aromatic%20plant%20extr%20methods.pdf)
*Soxhlet Extraction
*fractional distillation
*others?

2) '''Separation techniques'''
*GC
*HPLC

3) '''Characterization'''
*GC-MS
* NMR (low-field and high field)
:*Spectral Search (http://sdbs.db.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi)


4) Samples of oils and main compounds of interest. Kits?

5) "Smell" activity
