 +"A number of oleo-gum-resins called bdelliums are produced in Arabia and Somalia from various species of 
 +Commiphora and resemble myrrh; these were probably counted as myrrh in classical times and are probably used for adulteration today. The “perfumed bdellium” (opopanax or bisabol myrrh) is from C. erythraea." \\

 +"Opopanax oil and opopanax resinoid are obtained from the resin of Commiphora erythraea Engl. var. glabrescens Engl., a tree growing in Somalia (Burseraceae). The resinoid is prepared by solvent extraction, and steam distillation of the resin gives the essential oil, which is a yellow to greenish-yellow liquid with a warm, sweet, balsamic odor... Opopanax oil and resinoid are used in perfume compositions with oriental char-
 +acteristics, the resinoid also for its fixative properties." \\

 The resin essential oil of C. erythraea obtained by steam distillation contained two furanosesquiterpenoids as dominant constituents, 1(10),4-furanodien-6-one (21.5%), and 1,10(15)-furanogermacradien-6-one (14.3%), together with rel-3R-methoxy-4S-furanogermacra-1E,10(15)-dien-6-one (7.4%) and rel-2R-methoxy-4R-furanogermacra-1(10)E-en-6-one (3.9%). Minor components were eg. aromadendrene (4.4%), α-gurjunene (3.8%) and α-copaene (3.4%). "In our oil, we could not identify either ocimene, although this was the most abundant monoterpene of the opopanax oil studied by Ikeda, or α- and β-bisabolenes." \\ The resin essential oil of C. erythraea obtained by steam distillation contained two furanosesquiterpenoids as dominant constituents, 1(10),4-furanodien-6-one (21.5%), and 1,10(15)-furanogermacradien-6-one (14.3%), together with rel-3R-methoxy-4S-furanogermacra-1E,10(15)-dien-6-one (7.4%) and rel-2R-methoxy-4R-furanogermacra-1(10)E-en-6-one (3.9%).
