Essential oil
Essential oil of "A. herba-alba", from the Sinai Desert, contains mainly 1,8-cineole and appreciable amounts of α- / β-thujone as well as other oxygenated monoterpenes including terpinen-4-ol, camphor and borneol. Davanone, chrysanthenone and cis-chrysanthenol have been described as major constituents in some populations of "A. herba-alba" from Morocco and Spain. Less common non-head-to-tail monoterpene alcohols have been identified in some populations from Negev desert, such as "santolina" alcohol and "yomogi" alcohol.
