This is a sourcing and quality-control guide, not a medical or dosage reference. It's written for buyers evaluating raw-material consistency, not consumers.
Withanolides are the class of steroidal lactone compounds Ashwagandha (Withania somnifera) root is valued for. We don't publish specific withanolide percentages — content varies by plant, harvest and handling, and any supplier quoting a fixed number without lot-specific lab testing should be questioned. What buyers can control is root form consistency (grade), sourcing transparency, and requesting third-party lab testing (a Certificate of Analysis) on the specific lot they're buying.
Withanolides are a class of naturally occurring steroidal lactone compounds found in Withania somnifera (Ashwagandha), concentrated mainly in the root. They're the compound class most extraction buyers are targeting when they process root into standardized extract. This article covers sourcing factors relevant to raw-material buyers — it isn't a substitute for your own lab testing or formulation research.
| Question | Why it matters |
|---|---|
| Where is the root sourced from, and when was it harvested? | Traceability and harvest-season timing both affect material quality |
| Is grading done in-house, or bought pre-graded? | In-house grading gives more control and traceability than buying from an unknown reseller chain |
| Can you provide a Certificate of Analysis for this specific lot? | Only lot-specific third-party lab testing gives you an actual withanolide figure — generic marketing numbers don't |
| How is the root stored and handled before dispatch? | Poor storage degrades material regardless of initial quality |
| Is weighment done transparently at dispatch? | A basic but important trust signal for any bulk agricultural purchase |
We hand-grade every lot in-house at our Neemuch facility, source through transparent Krishi Upaj Mandi auctions, and weigh every consignment in front of the buyer or their transporter before dispatch. If your process requires a Certificate of Analysis or specific lab testing on a lot, raise it when you request a quote so we can discuss what's feasible for your order size — see our extraction buyers' guide for grade-specific recommendations.
