In a an experiment conducted several years ago to determine incurred pesticide residue in Kava root sample, it was observed that the Kava lactones such as Kawain, Dehydokawain and Yangonin produced Biphenyl*. It was a false postive generation of biphenyl since there was no incurred biphenyl on the Kava root sample extract. The biphenyl observed was due to the phenyl free radical generated by the homolysis of C9-C8 sanwitched between conjugated double bond in the structures of the above mentioned lactones under high heat in the inlet of GC-MS instrument. Since I have not found any reference/dicussion regarding the above biphenyl formation from phenyl radicals in the current literature of the free radical reaction mechanism, I want to call it "Pal's free radical reaction manifestation" So, I request any comment or suggestion regarding the above subject before I submit a paper describing the above mentioned free radical reaction mechanism.

 * Biphenyl was banned by FDA as a fungicide.
