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 with UV detection for the marker compound (boldine), and LC-MS for identity. The USP Herbal Medicines Compendium monograph for Peumus boldus leaf is still in development; testing against it is available and quoted.
Boldine is the main aporphine alkaloid in boldo leaf. Measuring it gives a check on both identity and strength of the leaf.
Yes. The monograph lists Cryptocarya peumus as a look-alike with similar leaves. The alkaloid and HPLC profile help separate true boldo from substitutes.
Yes, boldo leaf has a volatile oil with ascaridole and other terpenes. The standard test focuses on the alkaloid marker; volatile oil profiling by GC can be quoted separately.
