i am in the process of doing an extraction on some wild phalaris arundinacea with some of my aq1 trimmings mixed in. started with ~300g of fresh wet plant material picked at dawn, froze and thawed it several times to ease blending. blended the material, dropped ph to 5 and simmered in closed pan for ~8 hrs. strained through cheese cloth then filtered through coffee filters.
i ran in 2 batches, i simmered the second one for the full 8 while the first one went for only like 4 hrs. the second batch is filtering right now, taking for ever and the filtrate is much darker than the first batch. I am unsure whether this is due to more alkaloids and fats present from the longer simmer or from the filters breaking down. i put some naptha in there to defat the drops as they enter. the filtering has run over 48 hrs know across three different filters.
i have a vacuum filter setup on the way but it wont be here till early December courtesy of the shipping container issues.
when defatting the first batch the naptha remained clear, i do not know if this is normal. i then basified the and added naptha to begin the extraction. once again the solvent remained clear. yellow debris precipitated out of solution and some floats to the top and some to the bottom of the aqueous layer. these could be hydrolyzed fatty acids or some other contaminant.
I will do one extraction of the first batch every week for the next 3, according to the tek im following. i plan to evaporate the solvent and recrys the product in heptane.
attached are pictures of the soutions, the carboy/growler is the second batch currently filtering the Erlenmeyer is the first batch.
any recommendations or notes are welcome.
