Infra-red Spectra of the New Proline Derivative from the Apple

IN the work of McKee 1 and of Hulme 2 on apple, two substances have been isolated. One of these, from apple peel 2 , has been referred to as proline substituted, probably on the same carbon, with methyl and hydroxyl groups. The other, from apple twigs, has been referred to by McKee 1 and described a...

Zusammenfassung:IN the work of McKee 1 and of Hulme 2 on apple, two substances have been isolated. One of these, from apple peel 2 , has been referred to as proline substituted, probably on the same carbon, with methyl and hydroxyl groups. The other, from apple twigs, has been referred to by McKee 1 and described above by Urbach as 4-hydroxy-methyl proline, that is, the hydroxyl group is on the methyl side-chain.
