Myrrh resinoids

Myrrh oil and myrrh resinoids are produced from the air-dried gum of... 

Myrrh resinoids are obtained in 20-45% yield by extracting the gum with suitable solvents (e.g., toluene, hexane). They are wax-like, brown-yellow to red-brown masses with a balsamic odor and an aromatic bitter taste. Specifications depend on the solvents used. 

Myrrh oil and myrrh resinoids are produced from the air-dried gum of Commiphora myrrha (Nees) Engl. var. molmol Engl., C. abyssinica Engl, and C. schimperi Engl. (Burseraceae), shrubs that grow in Northeast Africa and Arabia. 

If the residue from the initial extraction is of a resinous nature, it is called a resinoid, e.g. benzoin, myrrh, frankincense. Many resinoids will yield essential oils when distilled if they contain sufficiently volatile aromatic constituents. 

Frankincense and myrrh can be prepared in the form of both resinoids and essential oils, whereas benzoin, which is insufficiently volatile to be distilled, is a resinoid only. Resinoids are used in the perfumery industry as fixatives that prolong the fragrance effects.
