Saikogenin D is isolated from Bupleurum chinense, has anti-inflammatory effects. Saikogenin D activates epoxygenases that converts arachidonic acid to epoxyeicosanoids and dihydroxyeicosatrienoic acids, and the metabolites secondarily inhibit prostaglandin E2 (PGE2) production. Saikogenin D results in an elevation of [Ca2+]i due to Ca2+ release from intracellular stores[1][2].

In Vitro	Saikogenin D (1-20 μM) inhibits PGE2 production induced by the Ca2+ ionophore A23187 in a concentration-dependent manner with an IC50 value of 3 μM in C6 rat glioma cells[1]. Saikogenin D (10-100 μM) elevates [Ca2+]i in a concentration-dependent manner with a EC50 value of 35 μM in the presence or absence of extracellular Ca2+ in C6 rat glioma cells[1].
