An assay for epoxide hydrase activity is described based on the difference in solubility between the epoxide substrate and its corresponding diol. The assay conditions for insect juvenile hormone I and an epoxide-containing juvenoid have been elucidated. In each case, the epoxide partitions into an isooctane phase while the diol partitions largely into an aqueous methanol phase. The assay is faster than chromatographic assays while showing similar or superior precision.
