ABSTRACT:
An improved procedure for the conversion of commercial hesperidin into high-purity, crystalline hesperetin is disclosed. This procedure comprises purifying the crude starting material by insolubles removal and precipitation, followed by cleaving the saccharides with a strong mineral acid in lower primary alkanol. The use of lower alkanol in this transformation facilitates the isolation of a high purity product uncontaminated by resinified sugars.
