How many naptha pulls,over what time period when doing a stb extraction with powdered Mimosa?

Just to add my own personal observations. First extraction, 6 x 50ml naptha pulls over the course of 24 hours on 50g mimosa hostilis in 750ml water and 50g NAOH. First four pulls yielded results, I had 450mg in total, nothing from the last two pulls. Second extraction, same method over the same time period. Resulted in 200mg first pull, 100mg on the second, then 4 x 50mg. Appreciate if someone could possibly provide insight as to why I had various results and others experiences using the stb method, cheers people :thumb_up:

Boundary condition
Temperature variation could play a role. Was it the same batch of bark each time? With sufficient agitation the polar/NP phases should equilibrate pretty quickly so there's no real need for the pulls to take that long, unless you were waiting for emulsions to clear.
As it looks like your yields are rounded to the nearest 50mg, is there a possibility of measurement error? What were you using for weighing? How well does it respond at lower values? Your two results are in the same ballpark, so they could be viewed as consistent enough. 0.9% is OK but not outstanding, 1% obviously a marginally better yield.
Without more detail it's hard to comment much more on your results and a sample size of N=2 isn't statistically significant. What form was the bark in? Did you process it in any way before adding the base? Was solvent re-used after freeze precipitation for any of your pulls? The extra 50mg the second time around could easily be explained if the solvent were re-used.

Thanks for the reply downwardsfromzero, I will give you more detail.
Firstly, the measurements are rounded up to the nearest 10mg, I have 3 decimal place scales.
Mimosa was finely powdered, 100g for two extractions. I used fresh solvent for every pull, let it evaporate till cloudy and freeze precipitate for 12 hours. It was my first time though so the fact it worked at all was epic haa :d Cheers buddy
