I have a Soxhlet extractor and was thinking of using it to see what interesting fragrance compounds I can obtain from common plants. I'm UK based btw - need to get that flag sorted.

Anyway, I was wondering if anyone else has tried this or had any suggestions?

There's a birch tree in my garden, perhaps the bark might yield something interesting? Or maybe larch needles?

As 'The fresh needles of the European larch (Larix decidua) in Spring, a deciduous conifer, when crushed smell of freshly cut grass with a hint of pine.'

I'm thinking of using isopropyl alcohol as the extraction medium.
