Formation of Leuco-Anthocyanins in Eucalypt Tissues

Abstract

Robinson and Seshadri have postulated that C6—CH(OH)—CH(OH)—CH(OH)—C6 is the form of the precursor of the various classes of anthoxanthidins, and the anthocyanidins (for discussion, see ref. 1). Recent work2 has shown that the leuco-anthocyanidins have the cyclic form of this structure: so that this class could be one of the first forms of polyphenolic compounds synthesized in the plant and be the precursor of the above substances as well as catechins and tannins. If this were so, one would expect appreciable amounts of leuco-anthocyanins to be formed in areas of intense metabolism.
