Py-GC/MS Analysis on Medical Components of Benzene/Ethanol Extractives of Fresh Ormosia henryi Leaves in Autumn

As one of the most expensive wood trees, Ormosia henryi has been planted more than 1000 mu in South China now. A mass of Ormosia henryi leaves was naturally abandoned and degradable so that the resources were wasted. Therefore, in order to overcome the negative effects, Py-GC/MS was used to analyze the extractives of Ormosia henryi leaves. Relative content of each component was determined by area normalization. The benzene/ethanol extractives contain 57 compounds namely thiophene, 2,5-dibutyl-, tetradecanal, rishitin, pyrrole, pyridine, 5-hexyl-2-methyl-, pyrene, hexadecahydro-, p-menth-8(10)-en-9-ol, cis-, pentadecane, oleic acid, octane, octadecanoic acid, nonanal, naphthalene, decahydro-, naphthalene, 1,2,3,4,4a,5,6,8a-octahydro-4a,8-dimethyl-2- (1-methylethenyl)-, hexanoic acid, 3-hexenyl ester, (z)-, hexadecanoic acid, methyl ester, hexadecanoic acid, 2-hydroxy-l-(hydroxymethyl)ethyl ester, hexadecanoic acid, heneicosane, glycerin, and so on. So the rare medicinal materials and rare spice is rich in the extractives of Ormosia henryi leaves. The byproducts can be used as not only top grade cosmetics and skin care, but also bio- energy.
