Abstract: An analysis of seed protein peptides by using SDS polyacrylamide gel electropho- resis, indicates that all members in Taxodiaxeae share three peptides with molecular weights of 24, 32 and 10 kilodaltons. Generally, seeds of this family contain 2 to 4 major peptides, and their molecular weights are distributed in two regions: 24-26 K and 29-36 K respectively. The quantity of these major peptides is near or even more than 50% of seed total protein content. This kind of protein profiles is similar to that of Taxaceae and Cephalotaxaceae rather than to that of Pinaceae.  On the other hand, a considerable difference was observed in peptides with higher molecular weights. Among different species within a genus, no difference has been found both in their seed protein profiles and in their needle peroxidases.  Based on the data cited here, it seems that the relationships among most genera of Taxodiaceae are not so closed as the rela-tionship among following genera: Sequoia, Sequoiadendron and Taxodium.Decontaminated thianthrene disproportion.
