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 nimbin and salannin, with LC-MS identity. Full testing to the USP Herbal Medicines Compendium monograph for Azadirachta indica Seed is available and quoted.
The limonoid markers nimbin and salannin are measured by HPLC. The oil's fatty acid profile is a separate GC test, quoted on request.
Azadirachtin breaks down with light, heat and moisture, and pressed oils usually contain less of it than the seed. Samples are stored cool and dark before analysis.
The monograph lists Melia azedarach, chinaberry, as a potential confounding material. The limonoid profile helps tell the two apart.
