Furanodiene Standardization & Grades
Myrrh resin is a mixture of a water-soluble gum, a resin and a volatile oil, and the ethanol-soluble resin and oil fractions carry the sesquiterpenes that define its character. Among them are furanodiene, furanoeudesma-1,3-diene, curzerene and lindestrene, which are furan-ring sesquiterpenes from Commiphora myrrha (T.Nees) Engl. A myrrh extract is standardized to furanodienes because they are the most abundant and most characteristic members of this family, and a figure for them tells buyers how concentrated the sesquiterpene fraction is.
| Grade | Assay & Method | Where It Fits |
|---|---|---|
| 1% Furanodienes | HPLC | Blends, oil-based fills |
| 20% Furanodienes | HPLC | Capsules, small fill weight |
The spread is wide, so grade choice follows dose and carrier. At 20% the extract carries twenty times the furanodienes of the 1% grade per gram, which allows a compact capsule. At 1% the powder keeps more of the resin matrix and is easier to blend at gram-level inclusion. The same resin is also supplied as a 10:1 ratio extract without a marker figure, the Myrrh Extract Powder, and as a milled resin, Myrrh Powder. A specification that must state furanodienes is met by this standardized grade.
The water-soluble gum fraction of myrrh is not part of this extract, which is made from the ethanol-soluble resin and oil fraction.
The resin is the part used. Myrrh tears are hand-collected from the dried exudate on the bark, sorted by color and size, and cleaned of bark and sand before extraction. The leaves, twigs and bark of the shrub carry little of the sesquiterpene fraction and are not used. A myrrh extract is therefore defined by the resin and by the furanodiene figure.
