Fenugreek Extract (4-HIL)
Fenugreek Extract (4-HIL)
Purity Levels
40% Iso Lucin 4-HIL by HPLC
Mechotech designs and manufactures turnkey Fenugreek (Trigonella foenum-graecum) seed extraction plants standardised to 40% Iso Lucin 4-HIL by HPLC — a non-protein amino acid (4-hydroxyisoleucine) marker quantified by reverse-phase HPLC assay. This is a distinct grade from Mechotech's other Fenugreek Extract line, which is standardised to 40% Lucin Saponins by Gravimetry: that plant targets the steroidal saponin/diosgenin fraction and releases on a gravimetric assay, while this plant is tuned to concentrate and preserve the polar, heat-sensitive 4-HIL amino acid fraction and releases strictly on HPLC assay against a 4-HIL reference standard. We supply the complete machinery — seed cleaning, milling, aqueous/hydro-alcoholic extraction tuned for polar amino-acid recovery, filtration, low-temperature concentration, solvent recovery, standardisation and drying — for the pharmaceutical, nutraceutical, and food ingredient industries.
Mechotech's HPLC-grade Fenugreek plant is engineered around the distinct extraction behaviour of 4-hydroxyisoleucine: unlike the moderately non-polar steroidal saponins recovered by the gravimetric-grade line, 4-HIL is a small, highly water-soluble amino acid that partitions preferentially into the aqueous phase, is prone to loss in high-temperature evaporation, and requires closer control of extraction polarity (solvent-to-water ratio) and holding time to prevent degradation and to keep co-extracted sugars and pigments from suppressing the HPLC assay response. Extraction, concentration and drying parameters on this line are set specifically to maximise 4-HIL recovery and stability rather than saponin yield, and every batch is released only after HPLC assay against a 4-HIL reference standard — not the gravimetric method used for Mechotech's other Fenugreek Extract grade. Built in SS 316L with integrated solvent recovery, PLC-based automation and full batch documentation, each plant is delivered as a commissioned turnkey system to GMP norms.

Manufacturing Process
Raw Material Reception & Cleaning
Fenugreek seed is authenticated, cleaned of stones and foreign matter, tested for moisture, and graded before processing.
Grinding
Cleaned seed is milled to a controlled, uniform particle size to maximise contact area for the polar solvent system used in the following step.
Low-Temperature Aqueous/Hydro-Alcoholic Extraction
Milled seed is extracted in closed jacketed SS 316L extractors using a solvent-to-water ratio tuned toward the polar end of the range, under controlled low temperature and multiple cycles, to favour 4-hydroxyisoleucine recovery over the steroidal saponin fraction.
Filtration
The crude extract is clarified through pressure leaf or plate-and-frame filter presses followed by cartridge polish filters to remove suspended seed fibre and mucilage ahead of concentration.
Low-Temperature Vacuum Concentration & Solvent Recovery
The filtered extract is concentrated in a falling-film / vacuum evaporator held at a lower temperature band than the saponin-grade process to limit thermal degradation of the amino-acid fraction, with solvent recovered and recycled.
Colour & Sugar Reduction (Optional)
Where required, activated-carbon or resin polishing reduces co-extracted pigments and sugars that would otherwise interfere with HPLC baseline resolution of the 4-HIL peak.
Standardisation
The concentrate is assayed by HPLC against a 4-hydroxyisoleucine reference standard and adjusted to the declared 40% Iso Lucin 4-HIL by HPLC specification before drying.
Drying & Quality Control
The standardised extract is spray- or vacuum-dried under a low-temperature profile to a free-flowing powder, then released after HPLC assay, residual-solvent, heavy-metal, microbial, and moisture testing with full certificate-of-analysis documentation.

Key Features
Low-Temperature Process Tuned to 4-HIL
Extraction and concentration temperatures are held lower than Mechotech's saponin-grade line to protect the heat-sensitive 4-hydroxyisoleucine fraction from degradation.
HPLC-Verified Standardisation
Every batch is assayed and released against a 4-hydroxyisoleucine HPLC reference standard, distinct from the gravimetric saponin method used elsewhere in Mechotech's Fenugreek range.
GMP Hygienic SS 316L Construction
Electropolished SS 316L product-contact surfaces use GMP hygienic design, with CIP operation between batches.
Closed-Loop Solvent Recovery
Integrated recovery returns solvent for reuse each batch, reducing fresh-solvent consumption.
Optional Colour/Sugar Polishing
Activated-carbon or resin polishing is available to keep pigment and sugar carryover from interfering with HPLC peak resolution.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
