No. The $250 test covers identity, purity and quantity by HPLC with UV detection for the marker compounds (sphaeranthanolide and 7-hydroxyfrullanolide), and LC-MS for identity. Full testing to the USP Herbal Medicines Compendium monograph for Sphaeranthus indicus aerial parts is available and quoted.
The compendium has separate monographs for the whole aerial parts, the powder and a hydroalcoholic dry extract. Tell us which form you have, since an extract is standardized to sphaeranthanolide and will read much higher than raw plant powder.
Sphaeranthanolide is the compound the dry extract is standardized to, and 7-hydroxyfrullanolide is another characteristic constituent of the plant. Finding both in the expected pattern supports the plant's identity and gives a measure of extract strength.
