Description

General description

Isorhamnetin belongs to the flavonoids class of compounds.

Application

Isorhamnetin may be used as an analytical reference standard for the determination of isorhamnetin in:

• Rat plasma samples by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) equipped with electrospray ionization (ESI) and multiple reaction monitoring (MRM) mode of detection.
• Lotus (Nelumbo nucifera) leaves by macroporous resin chromatography combined with HPLC-ESI-MS/MS.
• Powdered extracts and finished products samples of Ginkgo biloba by HPLC-MS.
• Human plasma and urine by high-throughput micro solid-phase extraction (μ-SPE), followed by analysis using UHPLC in interface with quadrupole time-of-flight mass spectrometry (Q TOFMS).

Biochem/physiol Actions

Isorhamnetin inhibits adipogenesis by interfering with differentiation of adipose stem cells, by a mechanism involving stabilization of β-catenin and up-regulating the Wnt signaling pathway.
