extracting the moss (7) polytrichum juniperinum

10/09/2007 memo

content: polytrichum juniperinum - Saori collected it from the forest - teabag size 2 x 1
equipment: soxhlet 150ml
medium: ethanol 96% 225ml
heating: 1〜2





result:
Difficult to adjust to the proper heating stand because the soxhlet is apparently too big for this. If it's 1 it's too weak and if it's 2 it's too strong. The bottom of the flask got burned. The character of the extract is:

- burned/baked apple
- caramel
- fish grill

Clearly it went wrong.

I tried again with the smaller soxhlet.


content: polytrichum juniperinum - Saori collected it from the forest - teabag size 2 x 3
equipment: soxhlet 100ml
medium: ethanol 96% 100ml
heating: 1

15:00 start
17:30 change the teabag
19:00 change the teabag
23:00 finish

collected +- 40ml

character of the extract:
- brown colord
- first seaweed / wakame / nori kind of smell that makes you think of the sea
- gradually it gets warmer, then smell of the dried leaves in the forest
- later more close to oak moss or iceland moss

Very satisfactory. The concentration is also good enough for adding it to the lotion I think.
