Rasana Leaf
Rasana Leaf
Purity Levels
2.5% Alkaloids
Mechotech designs and manufactures turnkey herbal extraction plants for Rasana Leaf, listed in the catalogue with a 2.5% alkaloids figure. Mechotech’s legacy page for Rasna Leaf names the leaves of Pluchea lanceolata, commonly known as Rasna, as the raw material, lists the raw material as air-dried, and says Rasna extracts are widely used in formulations for joint health and musculoskeletal disorders. The Sureka Life Sciences catalogue has no Rasna entry, so no further marker or assay method is stated. The spelling differs between the product tree (Rasana) and the legacy page (Rasna).
Mechotech’s Rasana Leaf plant is configured around the specific chemistry and processing requirements of the raw material. Built in SS 316L with integrated solvent recovery, automation and full documentation, each plant is delivered as a commissioned turnkey system. The figure 2.5% Alkaloids is the catalogue standardisation; the specification actually targeted is set during process development and pilot validation.

Manufacturing Process
Raw Material Preparation
Rasana (Rasna) leaf raw material is authenticated, cleaned, tested for moisture and milled to a uniform particle size to maximise solvent contact before extraction. The air-dried leaf feed form named in the legacy page is confirmed with the client.
Extraction
The prepared Rasana Leaf raw material is extracted with food-grade solvent (alcohol / aqueous) in closed jacketed SS 316L extractors under controlled temperature and over multiple cycles to recover the target constituents.
Filtration
The extract (miscella) is clarified through a plate-and-frame filter press followed by cartridge polish filters.
Concentration & Solvent Recovery
The miscella is concentrated in a falling-film / vacuum evaporator, with solvent recovered through the condenser return system.
Standardisation
The concentrate is assayed and adjusted to the client’s target specification (catalogue figure: 2.5% Alkaloids) before the final finishing step.
Drying & Quality Control
The standardised Rasana Leaf extract is kept as a concentrate or spray- or vacuum-dried to the required form, then released after assay, residual-solvent, heavy-metal, microbial and moisture testing.

Key Features
SS 316L Construction
Electropolished SS 316L product-contact surfaces with CIP operation between batches.
Closed-Loop Solvent Recovery
Integrated condenser-return recovery reuses solvent between batches and reduces solvent loss.
Standardised to Specification
In-process and batch-release assay are used to check the finished extract against its agreed target specification (catalogue figure: 2.5% Alkaloids).
Flexible Finishing
The extract can be finished as a concentrate or, with a matched spray or vacuum dryer, as a free-flowing powder.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
