Determination of podophyllotoxin and related aryltetralin lignans by HPLC/DAD/MS from Lamiaceae species
Hugo Neves Brandão,Hector Hugo S. Medrado,Juceni P. David,Jorge Mauricio David,José Floriano Barêa Pastore,Marilena Meira +5 more
TL;DR: It is demonstrated that several genera within Hyptidinae may potentially serve as an alternative source of podophyllotoxin, and, the extraction procedure as well as the exploratory study of lignans using multivariate methods revealed an intrinsic relationship between podophyLLotoxin and α-peltatin levels in different part of the plant.
