No. Slippery elm bark (Ulmus rubra) does not fit the standard $250 identity, purity and quantity test, so it is tested to the USP Elm monograph. Pricing is quoted.
Slippery elm's main constituent is mucilage, a mix of polysaccharides, and the USP monograph has no single marker compound to assay. Testing focuses on identity and on purity checks such as outer bark and foreign matter.
Most samples are cut inner bark, powder or capsules. Powder is harder to identify by eye, so a chromatographic fingerprint against known bark is the main identity check.
