Analysis on nano biomedical components of acetic ether extractives of cunninghamia lanceolata Biology by Py-GC/MS

Cunninghamia lanceolata is medicinal plant in South China, and its wood extractives are greatly applied in the therapy and protection of human diseases. Therefore, the nano biomedical components of the acetic ether extractives of Cunninghamia lanceolata biology were studied by Py-GC/MS to find new specific drug. 93 compounds of the extractives were identified. The main constituents were cedrol (18.76%), 1H-3a, 7-methanoazulene, 2,3,6,7,8,8a-hexahydro-1,4,9,9-tetramethyl- (9.05%), anthracene, 9-dodecyltetradecahydro-(8.06%), 1H-cycloprop[e]azulene, 1a,2,3,5,6,7,7a,7b-octahydro-1, 1,4,7-tetramethyl- (4.14%), naphthalene, 1,2,3,5,6,8ahexahydro-4, 7-dimethyl-1-(1-methylethyl)-, (1S-cis)- (3.64%), phenol, 2-methoxy-4-methyl- (3.13%), copaene (3.11%), 1-naphthalenepropanol, .alpha.-ethenyldecahydro-.alpha.,5,5,8atetramethyl-2-methylene- (2.76%), germacrene B (2.71%), naphthalene, 1,2,3,5,6,7,8,8a-octahydro-1,8a-dimethyl-7-(1-methylethenyl)- (2.66%), 1H-benzocycloheptene, 2,4a,5,6,7,8-hexahydro-3,5,5,9-tetramethyl-, (R)- (2.49%), camphene (2.44%), 2,4,6-octatriene, 2,6-dimethyl- (2.38%), caryophyllene (2.07%), etc. So the nano acetic ether extractives of Cunninghamia lanceolata biology are used as high-grade bioenergy materials.
