The three filtrates were combined, concentrated to give a methanolic, green slime (90 g) which was treated with 1 M HCl and then basified by adding 5 M NaOH with continuous stirring until a cloudy precipitate appeared.
By changing the elution solvent system from basified methanol to a mixture of 7:2:1 ethyl acetate/isopropanol/ammonium hydroxide, we were able to almost completely remove this impurity from the final extracts.
The organic phase was concentrated to 500 mL with a rotating evaporator and extracted with 0.2 M aqueous HCl (5x 200 mL), and the aqueous HCl phase was basified with NaOH to pH 11, extracted with CH[Cl.sub.3] (5x 300 mL), concentrated in vacuum, dried over [Na.sub.2]S[O.sub.4], and filtered.

Each time this solution was basified according to the basic strength of the other half.
The aqueous layers thus obtained, were basified with N[H.sub.4]OH (pH 11) and partitioned with C[H.sub.2]C[l.sub.2], affording, after filtration under N[a.sub.2]S[O.sub.4], crude alkaloid extracts (AE).
