total or named markers, as your specification states
Botanical (flower bud)
Marker compounds: chlorogenic acid (CAS 327-97-9), 3,5-di-O-caffeoylquinic acid, 4,5-di-O-caffeoylquinic acid, sweroside, secoxyloganin and centauroside
Method for the $250 identity, purity and quantity test: HPLC-UV marker-compound assay (caffeoylquinic acids and iridoids), LC-MS identity, against a reference standard, with results in 3 to 5 business days.
The USP Herbal Medicines Compendium monograph covers identity by HPTLC fingerprint and content of caffeoylquinic acids (chlorogenic acid and two dicaffeoylquinic acids) and iridoids (sweroside, secoxyloganin and centauroside) by HPLC.

Purity and quantity is $250 per sample (1 unit) and raw powder purity is $200 for 50 mg, with results in 3 to 5 business days. Send the material sealed and labeled, with the label claim and the form it contains.
No. The $250 test covers identity, purity and quantity by HPLC-UV measurement of caffeoylquinic acids and iridoids, with LC-MS identity. The USP Herbal Medicines Compendium monograph for Lonicera japonica Flower is still in development; testing against it is available and quoted.
Flowers of other Lonicera species are sold under similar names and have a different iridoid and caffeoylquinic acid pattern. Measuring both marker classes helps tell them apart.
Chlorogenic acid can isomerize to neochlorogenic and cryptochlorogenic acid with heat and in neutral solutions, so extraction conditions are controlled.
