As one of economic species of wood plants in the Orient, Quercus aliena was also considered as the important bioresource. The molecular characteristics of extractives from Quercus aliena wood was analyzed to better utilize this bioresource. Fresh Quercus aliena wood were pound to pieces and extracted by single extraction and three-step extraction. And then the extractives were obtained and analyzed by GC/MS. The leaching rule of wood extractives from Quercus aliena was obvious, and 21 compounds were identified from wood extractives. What?s more, the wood extractives contained the rich and rare drug constituents, such as 3,3,7,11- tetramethyltricyclo [ (4,11)] undecan- 1-ol, 3,3,7,11-tetramethyltricyclo [,11)]undecan-1-ol, 2,6,10,14,18, 22-tetracosahexaene, 2,6,10,15,19,23-hexamethyl-, all-E)-, etc. so the wood extractives of Quercus aliena could be suitable for the extraction of bio-drugs.
