Hello: having quite thoroughly and repeatedly read around this website, I might suggest some things.
Firstly I would say that it is ideal to use powdered bark, with more surface area exposed to your solution. It will be easiest for the alkaloids to migrate to the solution this way.
Furthermore, I'd say that 30 grams of MHRB is a quite small amount. Were you expecting typical yield of one percent, you may pull 300mg. And since you are splitting the extraction between two jars, that would make a potential 150mg per jar, which might not look like a bunch of crystals. I would say such an amount could be in with that oil.
I do not know about the acid soaks, but I have seen here more soaks suggested, and a warm water bath. I would personally be most confident in 4 boils, but it surely seems a matter of preference.
But assuming that your soaks pulled the spice out of the bark, I found this in the A/B overview

Quote:. There is some debate over the optimal pH for this step. It's known that with certain plants sources (like Chacruna), a pH of 9 is sufficient to achieve maximum yields. On the other hand, Mimosa extractors have found that a much higher pH is necessary; this is likely due to the effects of various phytochemical solutes on the polarity of the aqueous phase. In theory, the addition of excess salt to the aqueous phase of a Mimosa extract prior to defatting ought to accomplish the same thing as the tremendous excess of hydroxide, but I've not yet heard of this being successful.
So for one thing, it is possible that your PH was not quite high enough. I would suggest something like 12.5, but again this information varies across the the site.
People seem to have found that adding handful of salt prior to basifying is helpful as well.

7) added naphtha (50 ml) again and after 24 hours I made second pull to the same glass coaster. I let it evaporate
Here, I would say that at least four pulls might be needed to pull the majority of you spice. And your technique as described is a bit unclear to me:
Did you shake the first pull for four hours? That would be excessive. All you need to do is shake or slosh for some minutes, let separate, and repeat four or five times.
Pull off the solvent then immediately. If you let the NPS sit on naptha for a time, it will soak up some oils where it is contacting your solution.
Your post makes it sound like for the second pull, you let the naptha sit on top of your aqueous solution for 24 hours. This is unheard of to me, and could explain those oils in your picture.
Anyway, just some things to look at in the future, and nothing that is not somewhere amongst this site's glorious trove of information.
