Abstract
The purpose of this study was to investigate the distribution of terpenes in loblolly pine with respect to the potential impact of volatile organic compound emissions during drying. The total terpene content in the inside, middle, and outside of increment core sections from twelve 40-year-old loblolly pines was determined over a period of 14 months. A method for extracting and analyzing terpenes from increment core sections is described. The average terpene contents and standard deviations (in parentheses) in the heartwood, inner sapwood, and outer sapwood of the increment core samples were 2.3 (0.42), 0.77 (0.31), and 0.35 (0.16) percent, respectively. ...
