What the records describe

Constituents measured

Plant parts

Preparations

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
Lignans	Fruit unspecified	Solvent extraction	—	Chromatographic tests	Resolve DOI
Lignans	Leaves	Solvent extraction	—	Standard Chromatographic tests (paper- thin layer- and column chromatography)	No resolvable identifier
Lignans	Bark	—	—	Nuclear Magnetic Resonance (NMR)	No resolvable identifier
Lignans	Unspecified	Solvent extraction	—	Nuclear Magnetic Resonance (NMR)	No resolvable identifier

Genotoxicity testing

Outcomes of genotoxicity assays as recorded in the source. A negative assay is a result under those test conditions, not a clearance.

Outcome	Endpoint	Test	Tested organism	Metabolic activation	Source
Positive	chromosome aberration	chromosome aberration assay	House mouse (as animal)	Not applicable	No resolvable identifier
Positive	DNA damage and/or repair	micronucleus assay	House mouse (as animal)	Not applicable	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.
