A series of subtropical grasses and temperate grasses, herbs and legumes were analysed for the presence of extractable and bound condensed tannin (CT) using colorimetric analysis by the butanol-HC1 method. Condensed tannins are routinely purified using affinity chromatography with Sephadex LH-20 as
Indoline spirochromenes with condensed fragments in the indoline part of the molecules were synthesized. All of the compounds have photochromic properties. The introduction of a condensed fragment into the indoline part of the molecule leads to a bathochromic shift of both the long-wave and short-wa
