Rosemary Oil and Extract

In 1993, Panizzi et al. analyzed four oils produced from plants growing wild in Italy, among which was rosemary (ex. Rosmarinus officinalis L.). In addition to screening these oils for their antimicrobial properties, they determined that the rosemary oil studied had the following composition:

alpha-pinene (28.91%)

camphene (4.13%)

beta-pinene (1.62%)

myrcene (1.94%)

limonene (2.55%)

1,8-cineole (17.50%)

gamma-terpinene (0.69%)

p-cymene (1.34%)

camphor (7.35%)

linalool (2.35%)

bornyl acetate (0.88%)

beta-caryophyllene (1.32%)

alpha-terpineol (6.22%)

borneol (8.58%)

verbenone (0.42%)

geraniol (1.47%)

While examining the antibacterial properties of rosemary oil produced from plants growing in the Botanic Garden in Naples (Italy), Boato et al. (1994) determined that the main components of the oil were as follows:

alpha-pinene (27.6%)

camphene (8.5%)

beta-pinene (2.1%)

myrcene (1.1%)

alpha-terpinene (2.2%)

p-cymene (1.7%)

1,8-cineole (29.3%)

limonene (2.0%)

linalool (1.5%)

camphor (12.1%)

delta-terpineol (1.9%)

borneol (4.7%)

alpha-terpineol (2.4%)

bornyl acetate (2.3%)
