Research Leonurine extraction from Leonurus japonicus

[Ikarus42069]

Leonurus Japonicus grows wild where i live, so i tried doing a simple extraction based on some info i found online, sorry i didn't weight anything because i didn't really have hope, first i crushed a bunch of flowers and small leaves, added about 500 ml of hot but not boiling demineralized water to the flowers and let rest for about 5 minutes, then i filtered the solids, tried a small defat with a comercial mix of industrial organic solvents that does evap completely, then disolved citric acid was added until it changed color and a bunch of yellowish/beige precipitate started appearing, does anyone know what else other than leonurine hydrocloride it could be? any info would be greatly appreciated, will post pics once the precipitate is filtered and dried, Thanks.

Hi, welcome and thanks for sharingl

Were you following an established extraction procedure for leonurine? A bit of a search of the scientific literature should be productive in that respect.

Meanwhile, the precipitate could be impure calcium/magnesium citrate for all we know, although the coloration could be considered a tentatively positive sign.

Your next steps ought to include presumptive reagent testing, TLC, and sending a sample for analysis.
