This remains my favorite TEK to end up with clean harmalas.I have one question,- Is the first basing important to be done with NaOH instead of Na2CO3?When acidifying after the first basing, some impurities are no longer soluble. I think these are denatured plant material. If so, using NaOH may do a better job at "denaturing" than a gentler base.As far as yields go, I believe Na2CO3 is strong enough to crash the harmalas as shown in the VDS protocol. Na2CO3 could be used in the steps after using NaOH once (where the purpose of using NaOH is denaturing/cleanup).
