Leucoanthocyanins as the Possiblig Precursors of Extractives in Woody Tissues

Abstract

Leucoanthocyallins ill plant tissues have been estimated by moasuring tho nnthocyanidins produced after hoating with i8opropanol-hydroehloric acid in it closo(1 tuhe. Various tiSSllOS of fiJucalYT!tu8 sicberiarla F. Muoll., E. obZiqua I,'Horit., E. regnan8 F. Muol!., and Ii). maculata Hoole were studied by this method.
