Citrus × latifolia (Tanaka ex Yu.Tanaka) Tanaka - Rutaceae - Persian lime, Tahiti lime, Gewöhnliche Limette, Persische Limette, Tahitilimette

[C. ×aurantiifolia × C. ×limon]

„The evergreen, tree-like shrub is about 5-6 m tall. Branches are reinforced with up to 1 cm long spines. The leaves are dark green with a slight petiole outflanking, 6-7 × 10-13 cm large leaf blade (latifolius = broadleaf)… The fruit has a green shell, which is pale yellow when fully ripe. It measures about 5 cm in diameter.“

The major component of lime peel oil is limonene (40-45%), followed by γ-terpinene (17-21%) and β-pinene (11-13%). Minor components are α-thujene (0.4-0.7%), sabinene (1-2%), p-cymene(0.2-5%), α-pinene (1-2%), myrcene (1%), terpinolene (0.7-0.9%), β-bisabolene (1-2%), trans-α-bergamotene (1%), and α-terpineol (0.5%). Among oxygenated compounds, geranial (2-4%), neral (1-2%), neryl acetate (1-2%), geranyl acetate (0.7-2%), and linalool (0.4-0.5%) are found.

(geranial, neral)

„Quantitative results showed the superiority of milled material (7.93% w/w for CO2 extraction and 5.45% w/w for hydrodistillation) than the whole material (1.98%w/w for CO2 extraction and 0.97% w/w for hydrodistillation)… Percentage of the volatile components of lime oils obtained by different extraction process (extracted from table):
Hydrodistillation: d-limonene 47.5%, γ-terpinene 12.3%, β-pinene 12.4%, geranial 6.4%, neral 4.7%, α-terpineol 2.2%, β-bisabolene 1.8%, α-pinene 1.9%, sabinene 1.6%, myrcene 1.2%, cis-α-bergamotene 0.3%
CO2 extraction: d-limonene 48.9%, γ-terpinene 17.0%, β-pinene 14.5%, geranial 1.1%, neral 0.7%, α-terpineol 0.4%, β-bisabolene 3.3%, α-pinene 2.7%, sabinene 2.2%, myrcene 1.4%, cis-α-bergamotene 1.2%
Hydrodistillation gives fewer non-oxygenated compounds (81.2% vs. 93.3%) and more oxygenated (17.0% vs. 3.3%) and more citral (11.1% vs. 1.8%) than CO2 extraction (extracted from table).“
