The volatile oils from the Japanese and North Korean varieties of Angelica sinensis (Oliv.) Diels, cultivated in Vietnam, were obtained by steam distillation of the fresh leaves and whole flowers. The oils were analyzed by GC and GC/MS and found to contain about 50 compounds. More than 35 constituents have been identified, the major ones being γ-terpinene (59.2% and 44.3% in the Japanese leaf and flower oils; 68.3% and 62.3% in the North Korean oils), and (Z)-ligustilide (11.9% and 33.6%, 6.4% and 13.6%, respectively).
