Aqueous extracts ofMercurialis perennis L. contain a chromogen (hermidin) shown to be 3,6-dihydroxy-4-methoxy-1-methyl-2-pyridinone (2). The transient blue color formed by atmospheric oxidation of these extracts is due to a radical-anion and the final yellow-brown color is due to dimeric oxidation products.
