It is a sugar-rich fruit extract (glucose/fructose dominate) with fruity floral volatiles, not a volatile-oil class whose identity markers are sugars (glucose/fructose), with floral-fruity esters and terpene traces. Top fingerprints HPLC for sugars and GC for the fruity-floral volatile fingerprint as authenticity/quality markers.

Top fingerprints the sugar/volatile profile and screens for added sugar or synthetic flavour adulteration. Each COA reports soluble solids (Brix), moisture, heavy metals and micro; the identity is the natural Dimocarpus longan Lour. (longan) profile, not a single volatile oil.
