p. Arundinacea extraction Q?

[jamie]

so I evaporated the iso down and was left with a tiny bit of barely yellow resin stuff..smelled like pastic..so thats a good sign I guess..but it wasnt enough to be worth trying to scrap up..I only used 10 grams of grass to start with..I got rid of it..but it did smell strongly of indols..so now I will try with 100-200 grams of grass and do an extra sodium carbonate wash at the end and see what that will yeild..

When SWIM tried this he boiled 5 ounces of grass in pH 4 water, and evapped his acidic water, which left him with a goo that quickly became rock hard.

He chipped at it with a razor and dissolved most of it in water, no fats precipitated so SWIM basified to pH 11 and a ton of floating precipitate formed (note that the precipitate refused to settle, but formed a heavily saturated layer on top of the sol't).

SWIM planned to evaporate the precipitate saturated layer and test for activity, but SWIM is clumsy and he knocked over the bottle (ARGHHH!). He's going to try the next time he has a chance to get the grass.

SWIM believes that the step where the acidic water is evaporated is unnecessary and time consuming so he's not going to do it next time.

..I did the same thing with a chaliponga extraction last night...I was defatting an iso extraction with naptha..and I thought I hade put the lid on...but it wasnt screwed on..and I went to shake it one last time and it went all over the place..including me:x
