Potential resource materials from Ohio plants
Previously, the Northern Regional Research Center (NRRC) has studied chemical and botanical features of about 800 plant species in a program to identify potential renewable sources of industrial raw materials. In this program, another 64 species from northwestern and southwestern Ohio were studied for the present report. Aboveground samples were quantitatively analyzed for moisture, ash, crude protein, oil, polyphenol, and hydrocarbon. Plant oils were examined for classes of constituents. Oils were saponified and analyzed for yields of organic acids and unsaponifiable matter. Hydrocarbons were examined for the presence of rubber, gutta, and waxes. Rubber and gutta were analyzed for weight-average molecular weight and molecular weight distribution. Data are presented for 89 species of the 64 that gave the higher chemical yields. Rhus typhina gave outstanding yields of oil (6.5%) and polyphenol (30.8%) (moisture- plus ash-free basis). Liatris aspera yielded substantial amounts of oil (4.7%) and polyphenol (22.7%), whereas Cornus racemosa yielded a substantial amount of oil (4.4%) but a more typical yield of polyphenol (11.0%). Nuphar advena and Epilobium angustifolium had considerable amounts of polyphenol (16.2, 16.3%) but little oil. Nuphar advena contained the most crude protein (24.8%). Noteworthy amounts of hydrocarbon were extracted from Calamagrostis canadensis (1.1%), Aster umbellatus (0.8%), and Solidago riddellii (0.7%). Polyisoprenes in the hydrocarbon fractions of the latter 3 species were identified as gutta for C. canadensis and rubber for A. umbellatus and S. riddellii. Botanical features of the 8 species are briefly discussed.
