Cochineal Waxy Residues as Source of Policosanol: Chemical Hydrolysis and Enzymatic Transesterification

Figure 2

HPTLC chromatoplate: lanes A and E correspond to the triacontanol standard (Rf 0.73); lane B corresponds to the purified wax obtained by extraction with cyclohexane and cleaning with methanol and acetone; lane C is the methanolic fraction; and lane D is the acetonic fraction. Chromatograms of methanolic (a) and acetonic (b) fractions: peaks corresponding to 1, octacosanol; 2, triacontanol; 3, untriacontanol; and 4, tritriacontanol.
