Luteolin, 3',4',5,7-tetrahydroxyflavone, is a common flavonoid that exists in many types of plants including fruits, vegetables, and medicinal herbs. Plants rich in luteolin have been used in Chinese traditional medicine for treating various diseases such as hypertension, inflammatory disorders, and cancer. Luteolin possesses a variety of pharmacological activities, including antioxidant, anti-inflammatory, antimicrobial and anticancer activities. Numerous studies have shown that luteolin possesses beneficial neuroprotective effects both in vitro and in vivo.

Formononetin, an isoflavone, derived from Astragalus membranaceus, possesses the potential to reduce obesity and associated metabolic disorders. Formononetin displays estrogenic properties and induces angiogenesis activities. It regulates adipocyte thermogenesis as a partial PPARγ agonist and produces proangiogenesis effects through estrogen receptor alpha (ERα)-enhanced ROCK-II signaling pathways, by direct binding to the ligand-binding domain (LBD) of ERα. Besides, was shown, that formononetin inhibits HMGB1 release by decreasing HMGB1 acetylation via upregulating SIRT1 in a PPARδ-dependent manner and the identification of this process may help to treat inflammation-related disorders.
