By the using GC MS analysis there are 44 and 52 constituents from needles and branch were identified and accounting and essential oil. The main constituents of needles essential oil were α-pinene β-phellandrene β-pinene α-cadinol myrcene δ-cadinene . The main constituents of branchs essential oil were β-phellandrene α-pinene myrcene β-pinene abienol . α-cadinol . This is the first study on the chemical constituents of the essential oils from the needles and branchs of Abies delaveyi subsp. fansipanensis in Vietnam.
