Table 1: _Cont._While the seed EO was dominated by oxygenated derivatives of monoterpene hydrocarbons--primarily bornyl acetate (over 40%)--the cone EO contained over 90% monoterpene hydrocarbons, including \(\alpha\)-pinene, \(\beta\)-pinene, and myrcene. Other oxygenated monoterpencids in the cone EO were present in small quantities, such as \(\alpha\)-terpined (2.2%), _trans_-pinocarveol (1.5%), borneol (0.7%), and terpinen-4-ol (0.6%).
