Was curious if any botanists had information about the composition and analysis of the maple tree seeds or samara?

Googling has yielded little so far, though I did find an article published in 1918 by R. S. Anderson, and provided quite a bit, but I was also interested in enzyme contents, which his analysis did not provide any results.

His Results for the seeds from Acer saccharinum:

Code: 
Starch		41.94%
Protein		27.50%
Sucrose		15.78%
Pentosans	 4.07%
Galactan	 1.08%
Crude Fiber	 2.36%
Crude Fat	 3.55%
Ash		 5.01%

He does have results from the analysis of the ash and of the wings, but really interested in just the seed portion.

Any assistance is appreciated.

used to have a library (30+ years ago) of very old papers on tree seed analyses and germination requirments of those seeds. Try contacting them, give them the exact species you want, not just maple, and information you need.
 
Thanks, sent an email.
