Alkylphthalides with intracellular triglyceride metabolism-promoting activity from the rhizomes of Cnidium officinale Makino

AbstractMethanol extract of theCnidium officinale Makino rhizome, which is used as a crude drug Cnidium Rhizome (Cnidii Rhizoma; “Senkyu” in Japanese) and is listed in the Japanese Pharmacopoeia XVIII, showed intracellular triglyceride metabolism-promoting activity in high glucose-pretreated HepG2 cells. Thirty-five constituents, including two new alkylphthalide glycosides, senkyunosides A (1) and B (2), and a neolignan with a new stereoisomeric structure (3), were isolated in the extract. Their stereostructures were elucidated based on chemical and spectroscopic evidence. Among the isolates, several alkylphthalides, (Z)-3-butylidene-7-methoxyphthalide (9) and senkyunolides G (10), H (14), and I (15), and a polyacetylene falcarindiol (26), were found to show significant activity without any cytotoxicity at 10  μM.Graphical abstract
