摘要：

By incubation of germinating soybeans with mevalonate-[2-14C] (MVA), radioactivity was incorporated into four sapogenols which were identified by TLC. Unequivocal evidence for the identity of three of the four sapogenols was provided by co-crystallization to constant specific radioactivity. The partition of incorporated radioactivity into lipid- and water-soluble fractions and the pattern of radioactivity of individual sapogenols varied with the mode of administering labeled substrates to soybean seedlings, such as incubation of germinating soybeans with MVA-[2-14C], immersion of roots into MVA-[2-14C] or foliar application of squalene-[14C]. When alfalfa seedlings were incubated with MVA-[2-14C], about two-thirds of the radioactivity incorporated into the sapogenols was associated with medicagenic acid. © 1979.
