It is a coumarin-rich herbaceous concrete (coumarin-type and tobacco-like notes), a fragrance class rather than an edible-oil class whose identity markers are coumarin-type compounds with herbaceous tobacco-like volatiles. Top fingerprints GC-MS for the coumarin/herbaceous volatile fingerprint as authenticity/quality markers.
Top fingerprints the volatile profile and screens for synthetic coumarin or solvent residue issues. Each COA reports coumarin content, solvent residue (GB 5009.262), heavy metals and micro; the identity is the natural Lysimachia foenum-graecum Hance (Chinese sweet grass) profile, not a single volatile oil.
