The chemical reduction of the formyl group of pheophorbide b with sodium cyanoborohy dride in methanol leads to 71-methoxy-and 71-hydroxy-pheophorbide a. The same reaction with zinc pheophorbide b yields in addition zinc pheophorbide a. This was ch

During senescence of flowering plants, only breakdown products derived from chlorophyll a were detected although b disappears, too (Matile et al., 1996, Plant Physiol 112: 1403-1409). We investigated the possibility of chlorophyll b reduction during

Barley (Hordeum vulgare L.) etioplasts were isolated, and the pigments were extracted with acetone. The extract was analyzed by HPLC. Only protochlorophyllide a and no protochlorophyllide b was detected (limit of detection

The reduction of chlorophyllide b and its analogue zinc pheophorbide b in etioplasts of barley (Hordeum vulgare L.) was investigated in detail. In intact etioplasts, the reduction proceeds to chlorophyllide a and zinc pheophorbide a or, if incubated
