Great job physics envy! I'm so thankful and happy that it worked for you.
Now that you have what is likely complexed salvia you could try a water cleanup I think. Dissolve in water, the complexed HPBCD should still be very soluble in water and chlorophyll will not I think. Filter the water and dry again, you should get a cleaner product and very little water should be needed. Also, one could use anhydrous acetone and keep the undissolved HPBCD (big assumption here being that complexed HPBCD does not dissolve in acetone like HPBCD, an assumption that could be wrong). I still need to test these cleanup strategies and plan to do so one day, but would be great to hear of any results from others.
Also, another thing we can try is to start with the water solution from the last paragraph and add dilute HCl. HCl may attack the HPBCD and we should see salvinorin precipitating out. Mindlusion said this may work in the chat, so definitely worth a try at some point.
Regarding bitterness, have you tried HPBCD by itself? In my complexed extract the bitterness seems to be the same between the two and it subsides quickly. With cleanish HPBCD complexed extract the flavor should be the same as with pure HPBCD I think. To me it is slightly bitter but not unpleasant, where my plants are too bitter and unpleasant (which could be a function of the salvia clone too).
It would be very interesting to see how the complexed extract affects those who don't feel much effects when quidding. Do they feel more with the HPBCD complexed extract? If yes, that would indicate that the reason quidding is not effective for them is because of they have a different quidding absorption rate (different saliva/gum tissue/mouth ph) and not because of a different sensitivity to salvinorin once it is in the blood.
When I drank the dissolved complex I did it in quick gulps. I did not swish and tried to minimize the time in the mouth since I was trying to test absorption in the gastrointestinal track. Effects where more subtle and dreamy but lasted longer. Not sure when the effects started as they built up slowly, but I would say that after 30 minutes I was surely in a different head space.
There is a lot of work to be done. Need more folks to repeat these results as salvia can be tricky. I'm getting a neighbor to volunteer as a test subject soon. Then there is the
thymeleaved sandwort tea which infundibulum pointed to that could be combined with this.
Exciting stuff
