Research Area: Cancer Biological Activity: Diosmetin (Luteolin 4-methyl ether) is a bioflavonoid found in spearmint, oregano, and many other plants. Like all bioflavonoids, diosmetin helps maintain normal capillary permeability and fragility. Diosmetin is called a bioflavonoid because of its chemical structure which is similar to the chemical structure of flavones, as well as for its biological activity. [1,2] |
