Volatile constituents of Citrus sinensis L. (sweet orange) and Citrus Union L. (lemon) peels oil of Indian origin.

摘要

The composition of Citrus sinensis and Citrus Union essential oil samples have been investigated by GC and GC-MS. The essential oils were extracted by hydrodistillation method. The peels oil of Citrus sinensis afforded the identification of twenty monoterpenoid components comprising 99 % of the oil, including eight monoterpene hydrocarbons (91.86 %) and twelve oxygenated monoterpenes (7.3 %) in which limonene (87.78%) and linalool (4.04%) are the major constituents while Citrus limon afforded the identification of twenty six components comprising 94.5% of the oil, including eleven monoterpene hydrocarbons (56.38 %), nine oxygenated monoterpene (32.19 %) and six sesquiterpene hydrocarbons (5.93%). The major constituents of Citrus limon are limonene (35.25%) followed by α-terpineol (14.89%), γ-terpinene (8.11%) and β-myrcene (7.2%) .The Citrus sinensis oil mainly contains monoterpenoids while that Citrus limon contains both mono and sesquiterpenoids.
