Rhodesian teak tannin

Abstract An examination of the tannin from Rhodesian teak ( Baikiaea plurijuga ) heartwood suggests that it is principally an anhydropolyleucofisetinidin. The property of the timber of turning red when exposed to light is associated with this constituent. Hederagenin and pinitol were also isolated as heartwood constituents in addition to the already known baikiain.
