Nagori Cultivars & Soil Mineralization in Central India
The global demand for Withania somnifera has surged exponentially across dietary supplements, functional beverages, and sports nutrition. However, botanical efficacy begins with agricultural genetics. The premier commercial cultivar—Nagori Ashwagandha—is native to the arid limestone-rich soils of Rajasthan and Madhya Pradesh.
Nagori roots develop thick, fleshy taproots rich in natural starch and bioactive steroidal lactones, with significantly lower fibrous woodiness compared to wild-harvested shrubs. Jugrajj Food & Herbs contracts acreage directly with experienced growers, ensuring roots are harvested precisely at 150-180 days when withanolide synthesis reaches peak physiological concentration.
Solvent-Free Mechanical Pulverization vs Chemical Extracts
While chemical solvent extracts (using alcohol or hexane) provide concentrated markers, modern clean-label consumers increasingly demand 100% full-spectrum whole-root powders that preserve the complete, unadulterated synergy of natural botanical compounds without toxic solvent residues.
Our facility utilizes pure mechanical milling. Roots are thoroughly washed, air-cured, and pulverized using chilled closed-loop hammer and pin mills. Operating below 38°C prevents thermal oxidation of delicate withanolides, producing a micro-fine 80-100 mesh powder that meets clean-label specifications worldwide.
Standardized Withanolide Profiling: Withaferin A vs Withanolide A
Quality Ashwagandha root powder must balance active withanolides while strictly limiting Withaferin A (which is naturally elevated in leaf tissue and can cause cytotoxic irritation if consumed in excess). Our analytical testing guarantees:
- Total Withanolides: ≥ 2.5% to 3.5% by HPLC.
- Ratio Integrity: High Withanolide A and Withanone with Withaferin A < 0.5% (verifying authentic root origin without cheap leaf adulteration).
- Moisture: ≤ 7.0%; Total Ash ≤ 7.0%; Acid Insoluble Ash ≤ 1.0%.
Pharmacopeial Compliance: USP, Ph. Eur. & IP Standards
Our bulk Ashwagandha root powder complies with United States Pharmacopeia (USP), European Pharmacopoeia (Ph. Eur.), and Indian Pharmacopoeia (IP) monographs for herbal drugs. Full testing parameters include:
- ICP-MS Heavy Metals: Lead < 0.5 ppm, Cadmium < 0.2 ppm, Arsenic < 0.5 ppm, Mercury < 0.1 ppm.
- Microbiology: TPC < 50,000 CFU/g; Yeast & Mold < 500 CFU/g; Salmonella and E. coli absent in 25g.
- Pesticides: Non-detectable against 250+ chemical screen.
Supply Continuity & Scalable Contract Manufacturing
With annual processing capacity exceeding 300 metric tons, Jugrajj Food & Herbs guarantees consistent year-round supply contracts for domestic brands and global importers. Bulk orders are packed in 25 kg fiber drums with inner polyethylene liners or heavy-duty kraft paper sacks.
