Pterocarpus Marsupium Extract

Purity Levels

90% Pterostilbene by HPLC

Mechotech designs and manufactures turnkey herbal extraction plants for Pterocarpus Marsupium Extract, standardised to 90% pterostilbene by HPLC. Pterocarpus marsupium, known as the Indian Kino Tree, yields pterostilbene from its heartwood — a naturally methylated analog of resveratrol with a well-documented pharmacokinetic advantage: the added methyl groups improve oral bioavailability relative to resveratrol, giving it real and growing standing in the antioxidant and metabolic-health nutraceutical category. We supply the complete machinery to process the heartwood into an extract configured to the client’s target specification for the pharmaceutical, nutraceutical, food, and fragrance industries.

Mechotech's Pterocarpus Marsupium Extract plant is engineered around the specific chemistry of pterostilbene recovery from Pterocarpus marsupium heartwood. Because pterostilbene is a methylated stilbene — chemically closely related to resveratrol but with two methoxy groups in place of hydroxyl groups — it is more lipophilic and metabolically stable than resveratrol, a genuine, citable pharmacokinetic property that supports its oral bioavailability advantage and drives nutraceutical demand for standardised isolate grades. Built in SS 316L with integrated solvent recovery, automation, and full documentation, each plant is delivered as a commissioned turnkey system.

Plant Capacities

Plant Scale	Heartwood Throughput	Typical Use
Pilot	Configured to your feedstock and trial plan	Product development, pterostilbene-yield validation
Semi-Commercial	Configured between pilot and commercial scale	Contract manufacturing, scale-up trials
Commercial	Configured to raw-material supply and confirmed buyer volume	Export-grade continuous production

Reaching 90% pterostilbene isolate purity requires resin purification and crystallisation beyond basic extraction, which reduces finished-powder yield per kg of heartwood; we recommend a pilot plant to validate recovery and purity before scaling.

Manufacturing Process

Raw Material Preparation

Dried Pterocarpus marsupium heartwood is authenticated, tested for moisture, and milled to a uniform particle size to maximise solvent contact with the dense, lignified wood matrix before extraction.

Extraction

Milled heartwood is extracted with food-grade solvent (alcohol/aqueous) in closed jacketed SS 316L extractors under controlled temperature and multiple cycles to maximise recovery of pterostilbene and related stilbenoids.

Filtration

The extract (miscella) is clarified through a plate-and-frame filter press followed by cartridge polish filters to remove woody particulate.

Purification & Concentration

To reach the 90% pterostilbene isolate specification, the extract passes a macroporous resin adsorption/desorption stage to separate pterostilbene from co-extracted wood tannins and lower-value phenolics, then is concentrated in a falling-film / vacuum evaporator, with solvent recovered through the condenser return system.

Standardisation & Crystallisation

The purified concentrate is assayed by HPLC and crystallised or blended to the declared 90% pterostilbene specification.

Drying & Quality Control

The standardised extract is vacuum- or spray-dried into a free-flowing powder, then released after HPLC assay, residual-solvent, heavy-metal, microbial, and moisture testing.

Key Features

Heartwood-Matched Extraction Process
Size reduction and extraction parameters are engineered for Pterocarpus marsupium's dense heartwood matrix, maximising pterostilbene release compared with generic wood-processing setups.
SS 316L Construction
Electropolished SS 316L product-contact surfaces with CIP operation between batches.
Resin Purification to 90% Isolate Grade
An integrated macroporous resin adsorption/desorption and crystallisation train separates pterostilbene from co-extracted wood tannins, enabling the plant to consistently reach the declared 90% pterostilbene by HPLC specification.
Closed-Loop Solvent Recovery
Integrated condenser-return recovery reuses solvent between batches and reduces solvent loss.
Integrated Drying
A matched spray/vacuum dryer produces a free-flowing, low-moisture powder ready for encapsulation and blending.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.

Frequently Asked Questions

Does Mechotech supply the complete machinery for Pterocarpus Marsupium Extract?

Yes. Mechotech supplies the complete turnkey plant for Pterocarpus Marsupium Extract — heartwood size reduction, extraction, resin purification and crystallisation, filtration, vacuum concentration with solvent recovery, and drying — engineered, fabricated at our Hyderabad facility, installed, and commissioned as a single integrated system.

What specification can the Pterocarpus Marsupium Extract plant achieve?

The catalogue lists 90% pterostilbene by HPLC. The plant is configured to the client’s target specification; the specification achieved is established during process development and pilot validation, and each batch is released with batch-release testing and certificate-of-analysis documentation.

Which plant part of Pterocarpus marsupium is used, and why?

The heartwood is used, since pterostilbene and related stilbenoids are concentrated in the dense inner wood of the trunk rather than the bark or leaves, which is why the plant's size-reduction stage is engineered for a hard, lignified wood feedstock.

What is pterostilbene, and how is it different from resveratrol?

Pterostilbene is a naturally occurring methylated analog of resveratrol — the same stilbene backbone, but with two methoxy groups in place of two hydroxyl groups. This methylation is a genuine, well-documented pharmacokinetic advantage: it makes pterostilbene more lipophilic and metabolically stable, giving it better oral bioavailability than resveratrol. This is presented as a citable chemical/pharmacokinetic fact, not a medical efficacy claim.

Why does reaching 90% pterostilbene require resin purification, not just extraction?

Basic solvent extraction of heartwood yields a mixed concentrate containing pterostilbene alongside wood tannins and other phenolics. Reaching the 90% isolate specification requires an added macroporous resin adsorption/desorption stage to selectively enrich pterostilbene, followed by crystallisation — this purification train is included in Mechotech's turnkey scope.

What production capacities are available for the Pterocarpus Marsupium Extract plant?

Capacity for the Pterocarpus Marsupium Extract plant is configured to raw-material supply, confirmed buyer volume and investment timeline, starting at pilot scale; a pilot plant is recommended to validate parameters before scaling.
