Executive Summary
A nutraceutical manufacturer required a turnkey extraction facility to produce Bacopa monnieri (Brahmi) Extract standardised to 20%, 40%, 50%, and 55% Bacosides for domestic and international markets.
The objective was to maximise Bacoside recovery while preserving heat-sensitive phytochemicals, minimising solvent losses, reducing operating costs, and ensuring batch-to-batch consistency under GMP manufacturing conditions.
Mechotech successfully designed, manufactured, installed, and commissioned a Bacopa Monnieri Extraction Plant featuring advanced hydro-alcoholic extraction, vacuum concentration, purification, resin column enrichment, solvent recovery, spray drying, and PLC-SCADA automation.
Customer Background
The customer manufactures herbal extracts supplied to nutraceutical companies, Ayurvedic medicine manufacturers, pharmaceutical companies, functional food manufacturers, cognitive health supplement brands, and international botanical ingredient distributors. With increasing demand for standardised Brahmi Extract, the customer required a modern automated processing facility capable of meeting global quality standards.
Customer Challenges
Before modernisation, the customer encountered:
- Low Bacoside extraction efficiency
- Inconsistent standardisation
- High solvent consumption
- Long extraction cycles
- High energy costs
- Manual production leading to batch variations
- Poor solvent recovery
- Difficulty meeting export specifications
- Limited production capacity
Project Objectives
Mechotech was commissioned to deliver a facility capable of:
- Processing 5 MT/day of Bacopa herb
- Producing standardised extracts containing 20–55% Bacosides
- Maximising active compound recovery
- Recovering extraction solvent for reuse
- Reducing utility consumption
- Fully automating production
- Meeting GMP requirements
- Supporting future capacity expansion

Process Description
Raw Material Preparation
Fresh or dried Bacopa herb is cleaned to remove foreign matter before controlled milling to optimise extraction efficiency.
Hydro-Alcoholic Extraction
Prepared raw material is processed in stainless steel extraction vessels using optimised hydro-alcoholic solvent systems.
The extraction process ensures:
- Reduced degradation
- Uniform extraction
- High productivity
- Lower solvent usage
Primary Filtration
The extract is clarified using pressure filtration systems to remove suspended plant particles while preserving active phytochemicals.
Vacuum Concentration
The clarified extract is concentrated under vacuum at low temperatures.
Benefits include:
- Protection of heat-sensitive compounds
- Reduced steam consumption
- Improved product stability
- Efficient concentration
Purification
The concentrated extract undergoes purification to remove chlorophyll, sugars, tannins, and unwanted plant components.
Resin Column Enrichment
A specialised adsorption resin system selectively enriches Bacosides to the required concentration.
Advantages include:
- Higher purity
- Improved standardisation
- Better colour
Solvent Recovery
A closed-loop solvent recovery system recovers ethanol, supporting solvent reuse.
Recovered solvent is:
- Condensed
- Purified
- Recycled into production
Drying
Depending on customer requirements, the enriched extract is dried using:
- Spray Dryer
- Vacuum Tray Dryer
- Fluid Bed Dryer (Optional)
The final powder provides:
- Low moisture
- High Bacoside stability
- Long shelf life
Blending & Standardisation
Finished extract is blended to customer specifications before packaging.
