I did a chilled ethanol extract. After evapping I then room temp winterized 4:1 in methanol while spinning with some charcoal.
I filtered over alumina and then started to rotavap the methanol off. I noticed some weird stuff on the inside of my flasks. Looks kinda crystally? Can’t get it out without solvent so not sure how to test.
Didn’t think methanol would drop anything out like this either, especially under heat.
Anyone ever got wee crystals like these?
