title: [Studies on flavianic acids as color reference standard for thin-layer chromatography].
abstract: Various flavianic acids were prepared and examined for the preparation for color reference standard for thin-layer chromatography (TLC). Their analytical data were: IR spetra, their specific absorptions were same; no impurities were detected; specific odor-free. It was clear that the prepared flavianic acids were useable as color reference standards for TLC.
