Biosynthesis of Flavonoids [PDF]
Nature, 1960 SEVERAL workers have shown that lignin and the ‘B ring’ of flavonoids are formed in vivo from shikimic acid and certain C6C3 compounds. The latter compounds are frequently encountered in plant tissues1. The ‘A ring’ of flavonoids appears to arise from acetate units2.
