Bitter Orange Extract INCI Name Citrus Aurantium Amara Extract CAS 72968-50-4 EINECS ELINCS No 277-143-2 Synephrine Seville Orange Zhi Shi Naranja Agria Neroli Petitgrain Seville Orange Citrus Bergamia Citrus Bigaradia Citrus Vulgaris photo picture image Bitter orange has a complex chemical makeup, though it is perhaps most known for the volatile oil in the peel. The familiar oily residue that appears after peeling citrus fruit, including bitter orange, is this volatile oil. It gives bitter orange its strong odor and flavor, and accounts for many of its medicinal effects. Besides the volatile oil, the peel contains flavones, the alkaloids synephrine, octopamine, and N-methyltyramine, and carotenoids.

Main content: synephrine,C9H13NO2,0.24%~1.45%(g/g); N-methyltyramine,C9H13NO,0.19%~0.83%(g/g).

Other Phytochemicals: neohesperidin;nobiletin;5-o-desmethyl nobiletin; quinoline; narcotin;noradrenline;tryptamine; tyramine; naringin; rhoifolin; lonicerin. Citrus sinensis Osbeck also contains hesperitin;naringenin;isosakuranetin;carotene; riboflavine; tengeretin; 3,5,6,7,8,3'4'-methoxyflavone. Fruit peel contains violatile oil composed of d-limonene; d-linaloo. N-acetyloctopamine;gamma-aminobutyric acid.

Bitter orange peel contains a volatile oil with limonene (about 90%), flavonoids, coumarins, triterpenes, vitamin C, carotene, and pectin. The flavonoids have several useful properties, being anti-inflammatory, antibacterial, and antifungal. The composition of the volatile oils in the leaves, flowers, and peel varies significantly. Linalyl acetate (50%) is the main constituent in oil from the leaves (petit grain), and linalool (35%) in oil from the flowers (neroli). The unripe fruit of the bitter orange contains cirantin, which reputedly is a contraceptive.
