樟树种子中存在着ｃｉｎｎａｍｏｍｉｎ与ｃａｍｐｈｏｒｉｎ两种新的核糖体失活蛋白，电泳分析与Ｗｅｓｔｅｒｎ杂交结果表明ｃｉｎｎａｍｏｍｉｎ在９、１０、１１月份种子中的含量分别是８．９％，２６．８％和１１．５％，以１０月份种子的含量为最高。ｃａｍｐｈｏｒｉｎ的含量则分别为１．７％，２．５％与４．６％，随着种子的成熟而不断增加。８月份的幼嫩种子中检测不出ｃｉｎｎｍａｍｏｍｉｎ与ｃａｍｐｈｏｒｉｎ．这表明樟树核糖体失活蛋白的表达受到了发育进程的时态调控．樟树叶片中可能不存在ｃｉｎｎａｍｏｍｉｎ与ｃａｍｐｈｏｒｉｎ，即两者的合成似乎具有一定的组织特异性．ｃｉｎｎａｍｏｍｉｎ与ｃａｍｐｈｏｒｉｎ均为糖蛋白。
There were two new cacroma and camphorin inactivation proteins in camphor tree. Electrophoretic analysis and Western blot showed that the content of cinnamomin in seeds in September, October and November were 8.9%, 26.8% and 11 .5%, the highest content of seeds in October. The content of camphorin was 1.7%, 2.5% and 4.6% respectively, increasing with the maturity of the seeds. Cinnmamomin and camphorin were undetectable in young seeds in August. This suggests that the expression of camphor ribosome inactivation protein is regulated by the temporal progression of development. Cinnamomin and camphorin may not be found in the leaves of camphor trees, ie the synthesis of the two may seem to have some tissue specificity. Both cinnamomin and camphorin are glycoproteins.
