Hispidulin has been used as a calibration standard:

• in high-performance liquid chromatography (HPLC) for quantification of Clerodendrum petasites flavonoids
• in liquid chromatography/electrospray ionization mass spectrometry (LC/ESI-MS) analysis
• in reverse-phase high-performance liquid chromatography with a diode-array detector (HPLC-DAD) and high-performance thin-layer chromatography (HPTLC)

Hispidulin is a bioactive flavonoid with a variety of effects including antiproliferative, antifungal, anti-inflammatory, antioxidative and antiepileptic activity. Like EGCG, hispidulin appears to activate AMPK and inhibit the PI3K/Akt/mTOR pathway. The antiepileptic activity may be due to additional activity as a benzodiazepine (BZD) receptor ligand.
Hispidulin also exhibits antiosteoporotic anti-atheromatous, antispasmodic and anticancer functionality. It exhibits inhibition on α-glucosidase enzymatic activity. Hispidulin inhibits platelet aggregation and is more effective than theophylline. It also acts as a modulator of the γ-aminobutyric acid receptor (GABA) and blocks the release of glutamate synaptosomes associated with cortical neurons.
