How we scored it
Extract: all constituents are plant metabolites (n = 1); extraction solvent leaves no mass. No formula supplied. 1.0 / 1.0 = 1.00.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Dominant route is solvent extraction (water, ethanol or glycol-water) of the flowers of Butea frondosa (now Butea monosperma), harvested mainly in India. No commercially significant synthetic alternative exists.
