✦ Synopsis
The anthraquiiione pigment, emodin, has been isolated and its presence positively verified from a nonpolar extract of the dried, ground tubers of Rumex hyrnenosepalus. Isolation was accomplished by preparative TLC on silica gel layers. Identification was made by visible, IR, NMR spectroscopy and TLC, with use of commercial samples of emodin.
