Making a paste of cactus powder and calcium hydroxide is sufficient for this, yes?benzyme said:perhaps they didn't do it properly?
I tried it once, yields were not as nice as with xylene, but I did get off-white crystals after adding HCl and evapping. heat, and do multiple pulls.
but first and foremost...lyse those cells completely. otherwise, your yields will be low, regardless of what solvent you use.
