Extraction Technologies
Mechotech designs and manufactures turnkey herbal extraction plants for Gymnema Sylvestre leaf, standardised to 25% to 75% Gymnemic acids by Gravimetry & by HPLC. We supply the complete machinery — leaf cleaning, drying and milling, hydro-alcoholic extraction, filtration, vacuum concentration, closed-loop solvent recovery and drying — to convert Gymnema sylvestre leaf into a consistent, gymnemic-acid-standardised extract for the glycemic-support nutraceutical, pharmaceutical, and food-supplement industries. Candidate extraction technologies for gymnemic acids: Counter-Current Extraction (CCE), Ultrasound-Assisted Extraction (UAE), Hybrid Extraction and Microwave-Assisted Extraction (MAE) (4 in total).
Mechotech's Gymnema Sylvestre plant is engineered around the specific chemistry of the plant's triterpenoid saponin complex, the gymnemic acids: controlled hydro-alcoholic extraction of the dried leaf recovers this saponin fraction while managing the natural chlorophyll and tannin load that leaf-based botanicals carry into the miscella, and in-line filtration and decolourisation steps keep the finished extract within colour and clarity expectations for nutraceutical use. Built in SS 316L with electropolished product-contact surfaces, PLC-SCADA automation and full batch documentation, each plant is delivered as a commissioned turnkey system configured to the declared Gymnemic Acids specification.

Manufacturing Process
Each extraction method follows a different process — pick a method to see its steps.
Raw-Material Preparation
Gymnema leaves are cleaned and size-reduced so gymnemic acids can be reached by the extraction medium; particle size and moisture are set during process development.
Counter-Current Loading
Prepared gymnema leaves are fed into a multi-stage solid–liquid counter-current extractor where fresh ethanol/water or a suitable food-grade solvent meets the most-depleted material.
Counter-Current Extraction
Solvent flows against the solids across stages to draw out gymnemic acids; bed flow and fines management are verified during pilot work.
Extract (Miscella) Collection
The gymnemic acids-bearing miscella is collected from the fresh-feed end while spent solids are discharged from the solvent-entry end.
Concentration & Solvent Recovery
Solvent is removed from the clarified gymnemic acids-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.
Standardisation & Drying
The gymnemic acids extract is assayed against the declared target specification and dried or supplied as a concentrate, according to the requirement.
Raw-Material Preparation
Gymnema leaves are cleaned and size-reduced so gymnemic acids can be reached by the extraction medium; particle size and moisture are set during process development.
Slurrying
Prepared gymnema leaves are slurried with ethanol/water or water in the extraction vessel.
Ultrasonic Cavitation
Ultrasound creates cavitation that disrupts the plant matrix and speeds release of gymnemic acids; probe intensity, temperature and filtration behaviour are piloted.
Separation
Spent solids are separated by filtration or centrifugation and the extract is clarified before concentration.
Concentration & Solvent Recovery
Solvent is removed from the clarified gymnemic acids-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.
Standardisation & Drying
The gymnemic acids extract is assayed against the declared target specification and dried or supplied as a concentrate, according to the requirement.
Raw-Material Preparation
Gymnema leaves are cleaned and size-reduced so gymnemic acids can be reached by the extraction medium; particle size and moisture are set during process development.
Stage Sequence Selection
A deliberate combined extraction train is used: the sequence of stages is selected for gymnemic acids in pilot screening and each stage is designed separately.
First Assisted Stage
The first stage releases gymnemic acids from the prepared feed under controlled conditions set for that stage.
Second / Combined Stage
The second stage completes recovery of gymnemic acids from the partially extracted material; stage conditions are optimised separately.
Separation & Concentration
Spent solids are removed and the combined extract is clarified and concentrated; solvent is recovered where a solvent is used.
Standardisation & Drying
The gymnemic acids extract is assayed against the declared target specification and dried or supplied as a concentrate, according to the requirement.
Raw-Material Preparation
Gymnema leaves are cleaned and size-reduced so gymnemic acids can be reached by the extraction medium; particle size and moisture are set during process development.
Medium Mixing
Prepared gymnema leaves are mixed with ethanol/water or water in the microwave extraction vessel.
Microwave Heating & Extraction
Controlled microwave heating drives gymnemic acids out of the prepared feed in a short cycle; heating, moisture, solvent safety and temperature-sensitive targets are controlled, with limits set during process development and pilot validation.
Separation
Spent solids are separated by filtration or centrifugation and the extract is clarified before concentration.
Concentration & Solvent Recovery
Solvent is removed from the clarified gymnemic acids-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.
Standardisation & Drying
The gymnemic acids extract is assayed against the declared target specification and dried or supplied as a concentrate, according to the requirement.

Key Features
GMP Hygienic SS 316L Construction
Electropolished SS 316L product-contact surfaces use GMP hygienic design, with CIP operation between batches.
Leaf-Specific Decolourisation
An in-line decolourisation stage manages the chlorophyll and tannin content typical of leaf-based botanicals, keeping the finished extract's colour and clarity consistent.
Closed-Loop Solvent Recovery
Integrated recovery returns extraction solvent for reuse.
Wide Standardisation Range
In-process and batch-release assay support gymnemic acid standardisation anywhere from 25% to 75%, by gravimetry and HPLC, on the same processing line.
