Chemische Eigenschaften
Origanum oils are produced from the flowering herb of Mediterranean Origanum
(Lamiaceae) species, mainly Origanum vulgare L. ssp. hirtum. Spanish origanum oil is derived from Coridothymus capitatus Rchb., syn. Thymbra
capitata (L.) Cav. The oils differ mainly in their content of carvacrol and thymol,
which are major constituents. Oil with a high carvacrol
content is a yellowish-red to dark brown liquid with a spicy, herbaceous
odor, reminiscent of thyme.The color quickly turns to blackwhen in contact with iron.
