Recorded constituents
What analytical work has found in this species, at which plant part and preparation. A measured constituent is a fact about material, not about effect.
| Substance | Plant part | Preparation | Concentration | Analytical method | Source |
|---|---|---|---|---|---|
| Melatonin | Leaves | Solvent extraction | 435 Picogram/gram | Enzyme-linked immunosorbent assay (ELISA) | No resolvable identifier |
| Proanthocyanidins (condensed tannins) | Fruit unspecified | Solvent extraction | 109 Milligram-equivalent/gram | High Performance Liquid Chromatography (HPLC)/Liquid Chromatography (LC) | No resolvable identifier |

Boundary
A constituent measurement is a fact about material at a stated preparation, not a statement about what that material does in a person. An adverse-effect or genotoxicity record is an observation reported in a source, most often in an animal or laboratory model. Neither is a Metatron Health conclusion about causality, human risk or benefit, and the absence of a record is not proof that a preparation is safe. Nothing here is diagnosis, prescribing or individual medical care.
