Flavonoids Extraction Plants

Smoketree Extract Powder

Purity Levels

10% - 98% Fisetin by HPLC

Mechotech supplies the complete machinery for smoketree extract powder production, standardised to 10%-98% fisetin by HPLC. Smoketree (Cotinus coggygria, also called smoke bush — not related to tobacco) is a well-documented natural source of fisetin, a flavonol extracted from the wood and bark. Fisetin is a genuinely trending compound in nutraceutical research circles, with growing commercial interest in the senolytic and longevity-research category; this reflects real, documented market and research interest and is presented here as a market-category note rather than a medical or efficacy claim. Our turnkey plant extracts, purifies, concentrates, and spray-dries or crystallises fisetin into a standardised free-flowing powder for the nutraceutical, functional food, and pharmaceutical markets.

Mechotech designs and manufactures the smoketree extract powder extraction plant as a turnkey solution with SS 316L construction, low-temperature aqueous-ethanol extraction of milled wood and bark, integrated solvent recovery, and spray drying or crystallisation. The 10%-98% range reflects genuine grade-tiering: crude wood/bark extraction and concentration yields extract in the lower-to-mid range, while research-grade and high-purity fisetin isolates near the top of the range require an added resin-purification and crystallisation stage. The process is engineered to protect the heat-sensitive fisetin fraction while achieving a consistent HPLC assay and low moisture.

High-purity fisetin isolate grades near 98% require additional resin-purification passes and yield less finished powder per kg of wood/bark than crude grades. We recommend a pilot plant to validate the process route for your target grade before scaling.

Manufacturing Process

Raw Material Preparation

Dried smoketree wood and bark is authenticated, tested for moisture (target below 10%), and milled to a uniform particle size to maximise solvent contact and release of fisetin from the lignified wood matrix before extraction.

Extraction

Milled wood/bark is extracted with warm water or aqueous ethanol (40-70% v/v) in closed jacketed SS 316L extractors at 45-70°C. Multiple cycles with fresh solvent maximise fisetin recovery from the fibrous matrix while limiting thermal degradation.

Filtration

The extract (miscella) is clarified through a plate-and-frame filter press followed by 1-5 micron cartridge polish filters to remove woody particulate before concentration.

Purification & Vacuum Concentration

For research-grade and high-purity specifications, the extract passes a macroporous resin adsorption/desorption stage to enrich fisetin relative to co-extracted tannins and other wood polyphenols, then is concentrated in a falling-film evaporator at 50-65°C under vacuum with closed-loop ethanol recovery.

Standardisation

The concentrate is assayed by HPLC for fisetin content and blended, maltodextrin-adjusted, or crystallised to the declared grade within the 10%-98% specification before drying.

Spray Drying / Crystallisation & Quality Control

Crude-to-mid grades are spray-dried to a free-flowing powder; high-purity isolate grades are finished by crystallisation and vacuum drying. Each batch undergoes HPLC assay, residual solvent, heavy metals, microbial, and moisture testing before release.

Key Features

Full Grade Range on One Line
The plant is engineered to cover both crude wood/bark extraction (10%-60% fisetin) and high-purity isolate production (up to 98%) by adding a resin-purification and crystallisation train onto the base extraction-concentration line.
GMP Hygienic SS 316L Construction
All product-contact surfaces are electropolished SS 316L, using GMP hygienic design for botanical extract manufacturing, with clean-in-place (CIP) operation between batches.
Standardised 10%-98% Assay by HPLC
In-process and batch-release HPLC assay are used to check the finished powder against its declared fisetin specification for consistent, buyer-ready quality at whichever grade is targeted, including research-grade isolates.
Closed-Loop Solvent Recovery
Integrated condenser-distillation recovery returns ethanol for reuse each batch, reducing fresh-solvent consumption.
Wood/Bark-Matched Size Reduction
Milling equipment is sized for smoketree's lignified wood and bark matrix, ensuring consistent particle size and solvent penetration ahead of extraction — a different feed preparation profile from leaf- or root-based botanicals.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with a modular design that allows expansion without replacing core equipment.

Frequently Asked Questions

What is smoketree extract powder and why is it commercially extracted?

Smoketree extract powder is the concentrated extract of Cotinus coggygria (smoketree/smoke bush) wood and bark, standardised to 10%-98% fisetin by HPLC. Fisetin is a well-documented flavonol with strong current commercial and research interest as a nutraceutical ingredient, and standardised extraction delivers a consistently dosed, buyer-ready ingredient compared with raw wood material, which has variable fisetin content.

Is smoketree related to tobacco or any smoking product?

No. Smoketree (Cotinus coggygria) takes its common name from the smoke-like, feathery seed plumes the shrub produces after flowering, not from tobacco or any smoking-related product. It is an ornamental and wood/bark-source shrub, botanically unrelated to tobacco (Nicotiana species).

What does the 'senolytic' or 'longevity' interest around fisetin mean for this product?

Fisetin is currently a genuinely trending compound in nutraceutical and longevity-research circles, often described in the research literature under the senolytic category. Mechotech presents this as a factual note on current market and research interest in the compound category, not as a medical claim, anti-ageing guarantee, or statement of efficacy for any finished product. Buyers formulating in this category are responsible for their own regulatory and label-claim compliance.

Why does the fisetin specification range so widely, from 10% to 98%?

The range reflects genuinely different grades of the same botanical. Crude wood/bark extraction and concentration alone yields grades roughly in the 10%-60% band for bulk formulation use. Grades approaching 90%-98% are high-purity fisetin isolates, produced by adding a macroporous resin purification and crystallisation stage to strip out co-extracted wood tannins and other polyphenols — relevant for research-grade and premium supplement applications.

Which plant part of smoketree is used, and why?

Dried wood and bark are used, since fisetin in Cotinus coggygria is concentrated in the lignified stem and root wood rather than the leaves, which is why the plant's milling and extraction stages are sized for a fibrous wood/bark feedstock rather than a soft leaf matrix.

Does Mechotech supply the machinery for smoketree extract powder?

Yes. Mechotech supplies the complete turnkey machinery — wood/bark size reduction, extraction vessels, filtration, resin purification and crystallisation for high-purity isolate production, vacuum concentration with solvent recovery, and spray/crystallisation drying — engineered, fabricated at our Hyderabad facility, installed, and commissioned as a single integrated plant.

What testing method confirms the smoketree extract powder specification?

The declared 10%-98% specification is confirmed by HPLC assay on every batch, supported by residual-solvent, heavy-metal, microbial, and moisture testing for full certificate-of-analysis documentation required by regulated-market and research-grade buyers.

What production capacities are available for the smoketree extract powder plant?

Mechotech manufactures smoketree extract powder plants from pilot systems for product development to commercial-scale plants. Because high-purity isolate grades near 98% require additional resin-purification passes and yield less finished powder per kg of wood/bark than crude grades, we recommend a pilot plant to validate the process route for your target grade before scaling.
