| Abstract: | From the pollen of Zea mays, three brassinosteroids, castasterone, typhasterol and teasterone, were identified by GC/MS and/or 1H NMR. Their concentrations in the pollen were shown by GC/SIM to be about 120 μg/kg fr.wt. (castasterone), 6.6 μg/kg fr.wt. (typhasterol) and 4.1 μg/kg fr.wt. (teasterone). It was also found that the anther contained a fairly large amount of brassinosteroids by a bioassay. |
