... adetailed understanding of the biosynthesis of triterpenesaponins is required, including the enzymes catalyzing the sequence of reactions and the genes encoding theseenzymes. The biosynthesis ... olean-3b,24-di-acetoxy-12-ene, except for the presence of several back-ground peaks (the amount of authentic sample wasadjusted to equalize the height of both peaks in GC).When the extract was incubated with sophoradiol, ... isolated from the plant itself, but they wereidentified as the products of heterologously expressedtriterpene synthases [10,14,17,20,24]. Although the presence of some triterpenes (lupeol, b-amyrin,...
