Frankincense Frankincense Frankincense (also known as olibanum, , Arabic: ) is an aromatic resin used in incense and perfumes, obtained from trees of the genus "Boswellia" in the family Burseraceae, particularly "Boswellia sacra" (syn: "B. bhaw-dajiana"), B. carterii, "B. frereana", "B. serrata" ("B. thurifera", Indian frankincense), and "B. papyrifera". The word is from Old French ("high-quality incense"). There are five main species of "Boswellia" that produce true frankincense. Resin from each of the five is available in various grades, which depend on the time of harvesting. The resin is then hand-sorted for quality. The English word "frankincense" is derived from the
Saturate, aromatic, resin and asphaltene Saturate, aromatic, resin and asphaltene Saturate, Aromatic, Resin and Asphaltene (SARA) is an analysis method that divides crude oil components according to their polarizability and polarity. The saturate fraction consists of nonpolar material including linear, branched, and cyclic saturated hydrocarbons (paraffins). Aromatics, which contain one or more aromatic rings, are slightly more polarizable. The remaining two fractions, resins and asphaltenes, have polar substituents. The distinction between the two is that asphaltenes are insoluble in an excess of heptane (or pentane) whereas resins are miscible with heptane (or pentane). There are three main methods to obtain SARA results. One has lately
