Cannabis flower essential oil than twofold compared with pollinated hemp (8 L/ha). Sixty-eight components were detected by GC and GC/mass spectrometry (MS) in fresh bud oil distilled from high-potency, indoor-grown hemp. The 57 identified constituents were 92% monoterpenes, 7% sesquiterpenes, and approx. 1% other compounds (ketones, esters). The dominating monoterpenes were myrcene (67%) and limonene (16%). In the essential oil from outdoor-grown hemp, the monoterpene concentration varied between 47.9 and 92.1% of the total terpenoid content. The sesquiterpenes ranged from 5.2 to 48.6%. The most abundant monoterpene was β-myrcene, followed by trans-caryophyllene, α-pinene, trans-ocimene, and α-terpinolene. Another report said there were 140 terpenoids, dominated
