Phillygenin is a potential candidate in osteosarcoma therapy.Nitric oxide (NO) is a ubiquitous signaling molecule synthesized from various nitrogen sources. An analytical method to identify a nitrogen source for NO generation was developed using liquid chromatography with tandem mass spectrometry in combination with stable isotope labeling. Our method successfully detected the 15N-labeled NO-containing compound generated from 15N-labeled substrate nitrite in vitro and in vivo.Polymethoxyflavones (PMFs) contained in the peel
