Oil % (by distillation)			1.l %
Oil % (by extraction)
camphor % (w/w)					0.005%	2.25%	0.4%
volatiles % (w/w)						0.11%	5.57%	0.66%

PS Method: A known weight of sample is extracted 
with a  2mg/ml solution of Tridecane in ethanol. 
The resultant liquid is injected into the GC for 
Analysis.  OIL % (by distillation) is a v/w% figure.
