Structure Elucidation of Triterpenoid Saponins Found in an Immunoadjuvant Preparation of <i>Quillaja brasiliensis</i> Using Mass Spectrometry and ¹H and ¹³C NMR Spectroscopy

An immunoadjuvant preparation (named Fraction B) was obtained from the aqueous extract of <i>Quillaja brasiliensis</i> leaves, and further fractionated by consecutive separations with silica flash MPLC and reverse phase HPLC. Two compounds were isolated, and their structures elucidated using a combi...
