|Abstract(s):||Nordihydroguaiaretic acid (NDGA) is a powerful antioxidant that can be found in plants like Larrea tridentata (Zygophyllaceae), also known as creosote bush, which grows in semidesert areas of Southwestern United States and Northern Mexico . Several studies have demonstrated that NDGA has important biological activities with great interest in the health area, such as antiviral, cancer chemopreventive, and antitumorgenic activities . Extraction of bioactive compounds from plants is conventionally performed using a heat‐reflux extraction method. However, different techniques have been developed in order to decrease extraction time and solvent consumption, as well as to increase the extraction yield and enhance the extracts quality . The objective of this study was to develop a microwave‐assisted extraction (MAE) method for NDGA recovery from Larrea tridentata leaves, and compare the obtained results with those found by using the conventional heat‐reflux extraction (HRE).|
