I often consume passiflora tea and just played around with it a little bit and have made a wierd extraction.
I dropped the passiflora into a mix about 25%ethanol ,25%acetone ,50%hotvinegar(25%)(The shitton of vinegar has a use)
I let it soak in that for a day (For some reason it foams a little bit dont know if thats from added NaHCO3 to make any CaCO3 percipitate out of the water or if that the passiflora itself)
I let it evaporate and you end up with a really sticky but runny dark red/brown resin.
Now smell it if it smells like vinegar you can be sure that there is some acetone and ethanol still left in it.
Add warm water to redissolve let it evaporate repeat until no more vinegar can be smelled. Then wash 2 times more.
The result probably contains all active ingredients and can be dissolved to be processed further.
Dont forget to freeze the passiflora if you use fresh one to break up all the cells.
