“…These studies on D. ambrosioides oil have suggested that there are many chemotypes, for example, India oils, with the following major components: α-terpinene (65.4%), and p -cymene (29.4%) 38 ; α-terpinene (63.6%), p -cymene (19.5%), and ascaridole (6.2%) 39 ; α-terpinene (44.7%), p -cymene (21.3%), and ascaridole (17.9%) 40 ; ascaridole (38.0%), α-terpinene (37.7%), and p -cymene (16.7%) 41 ; ascaridole (40.7%), isoascaridole (22.7%), α-terpinene (17.9%), and p -cymene (8.5%) 42 ; p -cymene (36.3%) and ascardiole (31.2%) 21 ; α-terpinene (37.2%), isoascaridole (20.5%), and ascaridole (14.8%) 43 ; and α-terpinene (72.5%), p -cymene (20.6%), and terpinolene (2.5%). 44 In China, the D. ambrosioides oil was found to contain the following major components: menthol (31.3%), and α-terpinene (13.2%) 45 ; bornylene (42.6%), p -cymene (21.8%), ascaridole (18.4%), and α-terpinene (11.7%) 46 ; p -cymene (49.6%), α-terpinene (26.8%), and isoascaridole (8.2%) 47 ; ( Z )-ascaridole (29.7%), isoascaridole (13.0%), and p -cymene (12.7%) 48 ; and α-terpinene (32.9%) and p -cymene (24.2%).…”
