Chemical Properties
Parsley Seed Essential Oil: Parsley seed essential oil is obtained by steam distillation of the ripe seeds in approximately
1.5 to 3.5% yields. The oil has a warm, spicy odor with a bitter, warm, aromatic taste. Parsley Leaf Oil: Parsley leaf oil is
obtained by steam distillation of leaves and flowering tops in very low yields (0.06%). This oil exhibits a much harsher, herbaceous
note than the seed oil. Parsley Herb Essential Oil: Parsley herb essential oil is obtained by distilling the whole plant, excluding the
root. It is a pale-yellow to greenish-yellow liquid with a pronounced herbaceous odor and a warm, bitter, slightly burning taste.
Chemical Properties
Parsley leaf oil is produced by steam distillation of the aerial parts of the plant, including the immature seeds. It is a yellow to light-brown liquid with the typical odor of the herb.

The oil consists mainly of monoterpene hydrocarbons. Its main constituent is 1,3,8-menthatriene, which is important for the aroma of parsley leaves.
Physical properties
Parsely herb oil: It is a yellow-to-light brown liquid. It is soluble in most fixed oils, mineral oil
and alcohol. It is slightly soluble in propylene glycol and is insoluble in glycerin. Parsley Seed Oil: It is a more or less viscous, yellowish-
to-yellow-amber liquid that sometimes deposits crystals on being chilled. Seed oil is soluble in most fixed oils, mineral oil and
alcohol. It is slightly soluble in propylene glycol and is insoluble in glycerin. For additional characteristics refer to Burdock (1997).
Occurrence
Found in the seed of the herb Petroselinum sativum Hoffm. (Apium petroselinum l., Carum petroselinum Benth et Hook) of the family Umbelliferae.
Uses
Flavoring in foods and pharmaceuticals.
Uses
Parsley Seed Oil is traditionally used for soothing and anti-itching treatment in dermatological disorders. It may also be used as a preservative.Parsley Seed Oil is extracted from the plant’s seeds that contain an oil called apiol. It may cause allergic reactions in sensitive skin.
Definition
Extractives and their physically modified derivatives. Petroselinum crispum.
Preparation
By careful steam distillation of the ripe seed.
Essential oil composition
Main constituents, in addition to apiole, include α-pinene, myristicin, traces of conjugated coumarins,
ketones, aldehydes, a solid hydrocarbon (m.p. 69°C) and traces of phenolic compounds (Burdock, 1997).
Pharmacology
In pharmacological studies of Egyptian P. hortense (P. sativum), plant extracts
stimulated spontaneous activity of rat uterus and intestine in vitro and lowered blood pressure
and respiratory movements in anaesthetized dogs. Growth of rats was stimulated and uterine weight
was increased by parsley in the diet. The results suggested therapeutic uses of P. hortense as a
laxative, hypotensive, ecbolic and emmenagogue, and promoter of growth (Sharaf et al. 1969).
Safety Profile
Moderately toxic by ingestion. A human skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes
