• • • • • • • • Product Overview

                Isobavachalcone is a naturally occurring chalcone found in the seeds of Psoralea corylifolia (Buguzhi). It is one of the characteristic chalcones in this traditional Chinese medicine and serves as an important reference standard for quality control.

                With the molecular formula C₂₀H₂₀O₄ and a molecular weight of 324.37 g/mol, this compound appears as a yellow to yellowish powder. It is soluble in methanol, ethanol, and DMSO. The product is supplied at ≥98% purity as determined by HPLC analysis.

                Synthetic Process

                Isobavachalcone is obtained through isolation from plant sources:

                1. Extraction: Psoralea corylifolia seeds are extracted with organic solvents.

                2. Chromatographic Separation: The extract is fractionated using silica gel column chromatography.

                3. Purification: Preparative HPLC yields the pure compound.

                4. Identity Confirmation: Structure is confirmed by NMR and mass spectrometry.
