| | マンダリンオレンジ葉油 Usage And Synthesis |
| 定義 | 本品は、マンダリンオレンジ Citrus reticulata の葉から得られる精油である。[Citrus nobilis] | | 化粧品の成分用途 | 皮膚コンディショニング剤、香料 | | 化学的特性 | The petitgrain essential oil of mandarin is obtained by steam distillation of leaves, small twigs, and unripe fruits with
yields of about 0.3%. The oil is produced in several mandarin-growing areas (especially Algeria); however, production is somewhat
limited. The oil exhibits a fruital odor and a yellow-amber fluorescent color. | | 化学的特性 | Petitgrain bigarade oil is obtained in approximately 0.2% yields, by steam distillation of leaves and twigs of the bitter
orange tree; the leaves are the main starting material. Paraguay petitgrain oil (or petitgrain oil, South American) is obtained by steam
distillation of the leaves and twigs of a variety of C. aurantium L. growing semiwild or cultivated in Paraguay. Distillation using
superheated steam reduces hydrolysis of esters important for quality aroma. From either petitgrain bigarade or Paraguay petitgrain
oil, a terpeneless oil can be prepared by vacuum distillation. | | 化学的特性 | Petitgrain oil Paraguay is obtained from an acclimatized variety of the bitter
orange tree, C. aurantium L., which is grown in Paraguay. It is pale yellow liquid
with a characteristic, strong, pleasant odor, reminiscent of linalool and linalyl acetate.
d2020 0.882–0.893; n20D 1.455–1.463; α20D ?5 ° to ?1 °; solubility: 1 vol in 4 vol of
70% ethanol at 20 ℃; acid number:max. 1; ester number: 122–190, corresponding
to an ester content of 39–67% (calculated as linalyl acetate). The main constituents
are linalool (15–30%) and linalyl acetate (40–60%). A number of trace constituents contribute essentially to the odor.
Annual production in Paraguay is nearly 200 t.
Petitgrain oil bigarade is derived from the bitter orange tree C. aurantium L.,
grown in France, Italy, Spain, and North Africa, see also bitter orange oil, p. 199. | | 物理的性質 | Petitgrain Bigarade Oil: An Italian product, petitgrain bigarade oil is a pale-yellow to amber
liquid. Paraguay Petitgrain Oil: A South American product, Paraguay petitgrain oil is a yellow to brownish-yellow liquid. It is
soluble in most fixed oils and mineral oil (with opalescence and turbidity). It is relatively insoluble in glycerin. | | 物理的性質 | The oil is a dark-olive green liquid. | | 使用 | petitgrain oil is widely used in pharmacy and perfumery for its therapeutic and tonic effect. Its fragrance is fresh, invigorating, and slightly floral with a bitter note. Like neroli, real petitgrain (or petitgrain biguarade) is obtained by distilling the leaves of the bitter orange tree. Petitgrain bergamot, petitgrain lemon, and petitgrain mandarin are also produced. It may be irritating to the skin. | | 定義 | Extractives and their physically modified derivatives. Citrus aurantium, var. amara, Citrus. | | 精油の成分 | The main constituents of the essential oils include l-linalyl acetate, linalool, terpineol, and geranyl and
nerol esters. The petitgrain oil (reference sample France) contains terpenic alcohols (linalool 12 to 24%, terpineol 2 to 5%, nerol <1%
and geraniol 1 to 2%), terpenic ester (linalyl acetate 51 to 71%, neryl acetate 1 to 2%, geranyl acetate 1 to 3%) and terpenic hydrocarbons
(myrcene <1.5%, β-ocimene 0.2 to 2.2%, β-pinene 0.3 to 2.7% and limonene 0.4 to 8%) (CoE, 2000). | | 安全性プロファイル | Low toxicity by ingestion and skincontact. A combustible liquid. When heated todecomposition it emits acrid smoke and irritating vapors. |
