When formed by precipitation it is a lemon yellow powder, or in orange yellow, crystalline masses when prepared by sublimation. Almost insoluble in cold H,0, but suflicientiy soluble in hot H,0 to communicate to it a distinct yellow color by continued boiling mth H,0 it is decom-pi sed into H,S aud As,0,. Insoluble in dilute HCl but readily soluble ill solutions of the alkaline hydrates, carbonates, and sulphides. It volatilizes when heated. 

Several Citrus EOs contain high proportions of limonene (14) as its major component. Orange peels are used as sedative in several countries, and EOs obtained from Citrus aurantium L. (Rutaceae) fruit peels can contain as much as 97.8% of limonene (14). The anxiolytic and sedative properties of Citrus EO suggested by traditional uses have been assessed in mice (Carvalho-Freitas and Costa 2002 Pultrini et al. 2006) and also shown in a clinical setting (Lehrner et al. 2000). The relaxant effects observed in female patients in a dental of ce were produced with a C. sinensis (L.) Osbeck (Rutaceae) EO composed of 88.1% limonene (14) and 3.77% myrcene (15). 

Stimulant oils included jasmine, patchouli, ylangylang, basil, and rosemary active components included fenchone, 1,8 cineole, isoborneol, and orange terpenes (Lis-Balchin, 2006). There was considerable similarity in the sedative and stimulant effects of some essential oils studied physi ologically (e.g., their effect on smooth muscle of the guinea pig in vitro) and in various psychologi cal assessments, mostly on humans (Lis-Balchin, 2006). 

Bitter orange flowers and oil have reportedly been used in European tradition as prophylactics for gastrointestinal complaints, nervous conditions, gont, sore throat, as a sedative, and for sleeplessness.
