Hydroxymatairesinol (HMR) is a lignan found in Norway spruce (Picea abies). [1] It is an enterolactone precursor with anticancer activities. In rats, HMR decreased the volume of induced tumours and stabilised established tumours, as well as preventing the development of new tumours. [1] It has also shown anti-oxidant properties in vitro. [1]
HMR's chemical structure is similar to matairesinol. [2] At high concentrations, HMR has estrogenic properties, which are considerably weaker than those of estradiol. [2]
