Product Introduction
Griffonia Simplicifolia Seed Extract is a botanical extract from the seeds of the woody climbing shrub Griffonia simplicifolia, a species endemic to Ghana and Ivory Coast. Its main active ingredient is L-5-Hydroxytryptophan (5-HTP), which is a direct biochemical precursor of serotonin (5-HT).
This plant source provides natural L-isomer 5-HTP with higher bio-compatibility and a proven “Peak X-free” profile, a vital safety standard not met by synthetic tryptophan. Eosinophilia-Myalgia Syndrome (EMS) has been associated with Peak X contamination and it is still a major regulatory issue for the US and EU markets.
The extract is a pale grey to off-white powder with a faint herbal odour and a bitter taste. Slightly soluble in water, soluble in hot alcohol. M.P., about 270°.

Third-Party Testing
Shaanxi Hongda manufactures each batch internally and with third-party verification. Internal testing utilises HPLC, UV spectrophotometer and GC equipment. The external testing is carried out by laboratories SGS and Eurofins.
The following checks are necessary before shipping:
· HPLC Assay - indicates ≥98.0% 5-HTP on a dry basis
· Peak X Screening — confirms absence of cytotoxic contaminants related to EMS
Solvent Residue Analysis – verified no Class 1 or 2 solvents utilised; only ethanol and water utilised
· Heavy Metal Profiling — ICP-MS testing for Pb, As, Cd and Hg under 10 ppm total
· Pesticide Residue Detection – Meets Proposition 65 and EU Food Safety requirements
· Microbiological Testing – total plate count, yeast and mould, and pathogen screening
Full COA, MSDS and 3rd Party Test Reports available upon request.
Key Advantages
Not synthetic racemic natural L-isomer.The plant-derived 5-HTP’s chirality profile suggests higher biological compatibility than synthetic mixes – a key feature for clean-label positioning.
Peak X-Free verified.This is a non-negotiable requirement for US and EU compliance. Each batch is tested and documentation provided.
Thermal stability up to 120 °CThe extract is stable to pasteurisation and extrusion processes and can therefore be incorporated into functional food formats, such as meal replacement bars and shakes.
95% will pass an 80 mesh sieve.Consistent particle size provides reliable blendability and flowability throughout the manufacture of capsules and tablets.
Multiple certifications on one source.KOSHER, HALAL, VEGAN, ORGANIC (EU/NOP) and cGMP all under one roof lowers your vendor complexity.

Application Areas
This extract is utilised in three main B2B formulation categories:
1. Dietary Supplements for Mood and Sleep
Active substance used in capsules and tablets for emotional balance and sound sleep. To match the flow of excipients like magnesium stearate, the powder needs to be granulated and must be stable in test under compression.
2. Functional Foods in Weight Management
Used as a satiety agent in meal replacement shakes and bars. Formulators must consider the bitter taste profile (masking agents are usually used) and demonstrate thermal stability by extrusion or pasteurisation up to 120°C.
3. Nootropic & Synergistic Mixes
Often used in combination with GABA or Melatonin or L-Theanine. Stability against decarboxylation and resistance to hygroscopic clumping when mixed with adaptogenic substances are important quality requirements in these complicated blends.

Production Process
Shaanxi Hongda employs a controlled multi-stage extraction process:
Raw Material Selection → Cleaning & Drying → Solvent Extraction (Ethanol/Water) → Filtration & Concentration → Purification & Standardisation → Spray Drying → Sieving (80 mesh) → QC Testing → Packaging
All production is carried out in 100,000-level clean rooms. Solvent use is confined to ethanol and water (no methanol, benzene or Class 1/2 solvents) for compliance with all USP and EP monograph standards.
