Botanical (fruit)
Marker compounds: betulinic acid (CAS 472-15-1), oleanolic acid (CAS 508-02-1), ursolic acid (CAS 77-52-1), cyclic AMP (CAS 60-92-4)
Method for the $250 identity, purity and quantity test: HPLC-UV marker-compound assay (triterpenic acids and cyclic AMP), 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 triterpenic acids (betulinic, oleanolic and ursolic acids and their 3-keto analogs) and cyclic AMP by HPLC. Full testing to the USP Herbal Medicines Compendium monograph for Ziziphus jujuba Fruit is available and quoted.

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 triterpenic acids and cyclic AMP, with LC-MS identity. Full testing to the USP Herbal Medicines Compendium monograph for Ziziphus jujuba Fruit is available and quoted.
Jujube fruit is unusually rich in adenosine 3',5'-cyclic monophosphate (cAMP), and the monograph uses it as a second content marker beside the triterpenic acids.
No. Sour jujube seed, from Ziziphus jujuba var. spinosa, is a separate article with different markers such as jujubosides and spinosin.
