Carya cathayensis, the pecan fruit, is a nutritionally dense fruit with a unique taste that has become popular for consumption. The Carya cathayensis shell (SCC) is a by-product of C and there is a lack of the systematic analysis on the chemical composition. The volatile organic constituent characteristics of SCC and the change law of SCC groups were investigated. The results show that the 1,6,10-Dodecatrien-3-ol,3,7,11-trimethyl-, (E) exists in SCC extracts could be used to prevent myopia and to produce fragrance. SCC could be used to extract the Vitamin E that is used in medicine and beauty products. The. gamma. -Sitosterol could be developed into an effective antidiabetic drug. The biologically active VOCs, such as Phytol, acetate, Heptacosane, and Squalene were found in the SCC extractives. The petroleum ether extractive is the highest extract content, followed by ethanol extractive and benzene/ethanol extractive, indicating that the petroleum ether extractive has a large development prospect. The results of FTIR analysis confirmed that the compound group of SCC will not be altered by organic solvent extraction. There were three obvious stages during the thermogravimetry analysis of SCC: the first stage is (30°C-90°C), the second stage is (225°C-336°C), and the third stage is (336°C-386°C). The order of quality loss is highest in the second, followed by the third and finally the first. The three temperature points (90°C, 225°C, and 386°C) could use as the theoretical basis for the analysis of pyrolysis of the SCC. A great amount of new components are produced during the pyrolysis process of SCC extracts and residues, which provides a new method for multiple uses of SCC. The GC/MS results showed that the SCC contained aromatic compounds, alkanes, ethers, organic carboxylates Acids, anhydrides and salts, esters and alcohols, and amides. The echocardiography before and after the SSC extraction showed that the surface particles were reduced after the extraction, but the overall pore structure did not. This indicated that the overall structure of the SCC was hard. These results could be used to determine if the SCC could be used as a grinding material. This initial exploration of the effective components of SCC should allow other to make full use of SCC and provide a developmental scientific basis for further development.
