    Abstract: The present invention provides a rapid and inexpensive method for extractively isolating acidic lipopeptide antibiotics, such as those having a cyclic peptide or cyclic depsipeptide core, in high yield and purity. In particular, there is provided a method of extracting a variety of acidic lipopeptide antibiotics, directly or indirectly, into water immiscible organic solvents by using a divalent cation chelation procedure.
