Aurantio-obtusin is an anthraquinone isolated from Semen Cassiae, with anti-Inflammatory, anti-oxidative, anti-coagulating and anti-hypertension activities[1][2][3]. Aurantio-obtusin relaxes systemic arteries through endothelial PI3K/AKT/eNOS-dependent signaling pathway in rats, thus acts as a new potential vasodilator[2]. Aurantio-obtusin inhibits allergic responses in IgE-mediated mast cells and anaphylactic models and is potential for treatment for allergy-related diseases[3].
