Synthesis, characterization, and bioactivity of rosin quaternary ammonium salt derivatives [PDF]
Two series of rosin quaternary ammonium salts (QAS) were synthesized using the same path. The structure of the target products was characterized by HPLC, MS, IR, and 1HNMR, and the bioactivity was determined by filter paper method using Trametes ...
