Interpretive Summary:

Technical Abstract: Simmondsin and several related compounds are present in jojoba meal at about 11% concentration. Industrial scale processes have been developed to extract a simmondsin concentrate that contains 42% simmondsin and analogues. This research was undertaken to further purify the active constituents in as simple a process as possible. Methanol, chloroform, water, ethanol, acetonitrile, and acetone in various combinations and at various solvent:solids ratios were tested. A single solvent extraction was developed that increases the purity from 44 to 70%. Subsequent preparative chromatography gave fractions greater than 90% purity.
