Orange-yellow crystalline powder, soluble in organic solvents such as methanol, ethanol, and DMSO, derived from Cassia seed.
Obtusifolin, isolated from the seeds of Cassia obtusifolia, regulates the gene expression and production of MUC5AC mucin in airway epithelial cells via inhibiting NF-kB pathway[1]. Obtusifolin suppresses phthalate esters-induced breast cancer bone metastasis by targeting parathyroid hormone-related protein[2].
ChEBI: Obtusifolin is a dihydroxyanthraquinone.
This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG
