Phorbic acid

Nordal and his associates have studied organic acids in a variety of succulent CAM plants. Phorbic acid, an 8-carbon tricarboxylic acid, was detected in Euphorbia sp., Cereus, Opuntia, Kleinia, and Portulaca (Nordal and Ogner, 1964 ... [Pg.49]

Ting (unpublished) was able to show, however, that the main organic acids produced by dark CO2 fixation in Euphorbia loricata did not cochromatograph with pure, authentic phorbic acid (generously supplied by Dr. Nordal) and that the main organic acid was, in fact, malic acid Hence, it is unlikely that phorbic and piscidic acid play a predominant role in CAM. [Pg.50]

Finally, Nordal and Benson (1969) found phorbic acid in the latex fraction after light " C02 fixation by Euphorbia resinifera. They concluded on the basis of their experiments that phorbic acid is a secondary product produced in the latifer-ous vessels and is not a direct photosynthetic or dark fixation product. [Pg.50]
