Pharmacopoeial laxative formulations requiring USP-grade sennosides.
Senna extract standardised for sennosides — from 20% nutraceutical grades to 60% USP pharmacopoeial grade.
Pharmacopoeial-grade sennoside extracts from leaf and pod, including a 60% USP grade.
Senna (Cassia angustifolia) is a pharmacopoeial laxative botanical, and its sennoside extracts are a long-established, high-volume product for CTA. We extract both leaf and pod material and standardise for total sennosides across a wide range of grades.
CTA produces 20–40% sennosides by HPLC, 20–60% by UV (BP method), and a 60% USP grade assayed by spectrofluorometry. The process library covers an extraction plan, a purified-fraction (PHD) upgradation plan, recrystallisation, an ethanol-byproduct grade and a resin-purification route — giving buyers a sennoside grade matched to either a nutraceutical or a pharmacopoeial dossier.
CTA supplies Senna across multiple grades. Custom specifications are developed against a documented buyer requirement.

All values are typical specifications and are confirmed batch-by-batch on the Certificate of Analysis. Custom specifications can be developed against a buyer's documented requirement. Values are indicative and to be confirmed by CTA's technical team before publication.
CTA's sennoside programme is a documented, multi-route process — a high-volume speciality:
A documented process library is what separates a speciality product from a commodity — it makes grades reproducible and lets CTA develop a custom specification with confidence.
Statements describe traditional use and the role of the active in normal body function. They are structure–function statements and not claims to diagnose, treat, cure or prevent any disease.

Classical and proprietary formulations using senna.
Standardised senna actives for finished-product brands.
Senna is a pharmacopoeial botanical with established IP / BP / USP monographs and is permitted under FSSAI for the relevant applications. Pharmacopoeial documentation is provided on enquiry.
Note: grades, marker percentages and regulatory status are indicative and to be confirmed by CTA's technical and regulatory team before publication.
The grades differ in assay method and specification. CTA produces 20–60% sennosides by the UV (BP) method and a 60% grade compliant with the USP assay (spectrofluorometry). The right grade depends on the pharmacopoeia the buyer's dossier follows.
Both. Leaf and pod material are extracted; the source is declared on documentation, and the grade is standardised on total sennoside content.
Yes. Sennosides are an established, large-volume line, manufactured through a documented multi-route process for consistent bulk supply.
