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 anthocyanins, with LC-MS identity. The USP Herbal Medicines Compendium monograph for Hibiscus sabdariffa Flower is still in development; testing against it is available and quoted.
The monograph covers the dried calyces and epicalyces, the red fleshy parts around the fruit, not the petals or leaves.
Anthocyanins break down with heat, light and higher pH, so drying and storage affect results. Extracts are prepared under acidic conditions to keep them stable.
