AROMA 303 Module 3: Constituents of Essential Oils Exam
#1 Questions with correct answers
The essential oils from the seeds of Parsley, Celery, and Dill contain this
compound. It was formerly extracted and used as an emmenagogue drug and to
induce abortion. In excess, it is neurotoxic, hepatotoxic, and nephrotoxic;
fatalities have been recorded. Sabinene; Apiol; Asarone; or Carvone - ✔✔Carvone
The compound is an oil-soluble phenylpropanoid called apiol (named after Celery,
Apium graveolens). Symptoms of apiol toxicity include cognitive and visual
disturbances, vertigo, tinnitus, and ataxia; higher doses induce convulsions,
paralysis, and death.
β-Asarone and α-asarone are compounds that are embryotoxic and teratogenic at
high does in mice. They are also hepatoxins, cardiotoxins, and carcinogens in test
animals. Which of the following plants does not contain these oil-soluble
phenylpropanoids? Wild carrot; European Wild Ginger; Calamus; or Boldo. -
✔✔Boldo
β-Asarone and α-asarone are found in a small number of medicinal herbs
including Calamus (especially in the Indian varieties, which can have as much as
96 %), European Wild Ginger and possibly other Asarum species, Wild Carrot
seed, and Sassafras root. They do not normally occur as constituents of Boldo oil.
Which monoterpene, which occurs in the essential oil of Parsley, has been used in
very small doses as an emmenagogue drug and abortifacient? Apiol; Metyl
salicylate; asarone; ascaridole. - ✔✔Apiol
, Apiol (sometimes called apiole) is an oil-soluble phenylpropanoid which occurs in
the essential oil of Parsley, and Celery seed; This monoterpene has been used in
very small doses as an emmenagogue drug and abortifacient.
Due to its unusual endoperoxide bridge, this monoterpene is quite effective at
killing intestinal worms. However, an excess is toxic; symptoms of poisoning
include digestive irritation, nausea, vomiting, vertigo, ataxia, and sensory
disturbances: Ascaridole, Asarone, Apiol, or Anethole. - ✔✔Ascaridole
Ascaridole (named after the roundworm, Ascaris lumbricoides) is the major
constituent of American Wormseed oil and is also found in Boldo. Wormseed oil
(Oil of Chenopodium) was once a popular anthelmintic, but can be toxic to the
CNS and digestive systems. Fatalities have been recorded from using the oil as a
wormer with domestic animals.
Which unusual anthelmintic monoterpene has an endoperoxide bridge? Apiol;
Methyl salicylate, Asarone, or Ascaridole - ✔✔Ascaridole
Ascaridole is an unusual monoterpene with an endoperoxide bridge found in
American Wormseed. Fatalities have been recorded when the oil was used as a
wormer with domestic animals. (Ascarids are a class of intestinal worms)
Which monoterpene constituent occurs as a mixture of two isomers, and both
isomers been associated with neurotoxicity. Pulegone; Methyl salicylate; Thujone;
Ascaridole? - ✔✔Thujone.
Thujone occurs as a mixture of two isomers, α-thujone and β-thujone. Alpha-
thujone is approximately twice as neuroactive as beta-thujone. Both have effects
