Yield after recrystallization:Brazilian:Mexican:Extraction procedure:For both types of bark...
1) 454g of bark was split into 2 half-gallon mason jars and the jars were filled with acidified water.
2) Jars were pressure cooked at 15 psi for one hour.
3) Liquid was poured off and reduced. More water was added.
4) Steps 2 and 3 were repeated 4 times.
5) Acidified MHRB solution was poured into a jug and based.
6) 75ml of naphtha was added and the jug was agitated.
7) Naphtha was pulled and collected in an evaporation dish which was left out. Crystallization was visible.
8 ) Steps 6 and 7 were repeated 4 times.
9) The evaporation dish was sealed and put in the freezer.
10) 75ml of xylene was added to the jug and agitated.
11) Xylene was pulled and placed in a jar.
12) Steps 10 and 11 were repeated.
13) Naphtha evaporation dish was pulled out of the freezer, crystals were collected and excess naphtha was poured off and evaporated.
