Liquid–Liquid Extraction (LLE)
Solvent-based liquid–liquid extraction for separating and concentrating target compounds from complex botanical matrices, operated as a contract service.
CTA's manufacturing platform covers herbal extraction, phytochemical purification, essential-oil and oleoresin processing, value-added spice handling and pilot-scale scale-up.
CTA extracts medicinal and aromatic plants into standardised extracts assayed to a defined active-marker percentage. Water, hydro-alcoholic and solvent routes are operated, and extracts are produced as ratio extracts or standardised to a marker compound by HPLC, UV, gravimetry or titration.
The catalogue runs to more than 120 standardised extracts — the foundation of our herbal-extracts business.
Beyond standardised extracts, CTA purifies individual phytochemicals to high assay — curcuminoids, piperine, caffeine, chlorogenic acid, lutein, berberine and others. Purification draws on crystallisation, recrystallisation, resin adsorption and fractionation.
CTA offers contract extraction and purification services to pharma and nutraceutical companies that need a specific molecule isolated or upgraded.
Solvent-based liquid–liquid extraction for separating and concentrating target compounds from complex botanical matrices, operated as a contract service.
Solvent extraction and purified-fraction upgradation routes to take a basic extract to a higher-assay, cleaner pharmaceutical-grade active.
CTA processes spice and botanical raw materials into essential oils and oleoresins — black pepper, ginger, turmeric, cardamom, clove, nutmeg and more — for the food, flavour and fragrance industries.
A complete value-added line for spices, herbs and botanicals — from incoming cleaning to finished, sterilised, packed product.
Removal of foreign matter, dust and extraneous material from incoming raw botanicals.
Steam sterilisation to reduce microbial load while protecting the botanical's character.
Milling to a buyer-specified mesh — coarse cut to fine powder.
Custom spice blends, seasonings and multi-botanical formulations.
Bulk packing and small pouch / sachet packing for retail-ready formats.
Every lot screened and released by the in-house analytical lab.
Quality & lab →A dedicated pilot-scale plant lets CTA trial new products, validate process routes and carry out technology transfer before committing to commercial-scale manufacture. It is the bridge between a developed process and reliable bulk supply — and the engine behind both our speciality programme and our contract-manufacturing service.
