Raw Material Research

Raw Material Research – CCRAS Focus

The Central Council for Research in Ayurvedic Sciences (CCRAS), headquartered in New Delhi, is the apex organization under the Ministry of AYUSH responsible for:

• Sourcing, authenticating, and standardizing medicinal herbs.
• Establishing pharmacognostic, phytochemical, and pharmacological parameters.
• Supporting the development of Pharmacopoeial Standards for the Ayurvedic Pharmacopoeia of India (API).

This ensures that all raw materials used in Ayurvedic formulations are safe, genuine, and consistent in quality.

1. Objectives of Raw Material Research (CCRAS)

1. Authentication: Identify and confirm the correct botanical species of medicinal herbs used in classical Ayurvedic formulations.
2. Standardization: Develop scientific parameters to ensure consistent quality of raw materials.
3. Conservation & Cultivation: Promote sustainable sourcing through Good Agricultural and Collection Practices (GACP).
4. Documentation: Create a national database of raw drug specimens and their quality parameters.
5. Collaboration: Support the Pharmacopoeia Commission for Indian Medicine & Homoeopathy (PCIM&H) in monograph preparation for inclusion in the Ayurvedic Pharmacopoeia of India.

🔬 2. Research Areas Covered

A. Sourcing of Medicinal Herbs

• Conducting field surveys across India to identify geographical regions rich in medicinal flora.
• Collection and cataloguing of raw drugs from different agro-climatic zones to study natural variations.
• Collaboration with National Medicinal Plants Board (NMPB) for sustainable cultivation programs.
• Establishment of Raw Drug Repositories (RDRs) at multiple regional centers:
  • Tarikhet (Uttarakhand)
  • Jhansi (Uttar Pradesh)
  • Chennai (Tamil Nadu)
    Each repository maintains authenticated herbarium specimens and voucher samples.

B. Pharmacognostic Studies

• Macroscopic and microscopic identification of crude drugs (leaves, roots, bark, seeds, etc.).
• Study of diagnostic cellular structures under the microscope for correct identification.
• Preparation of pharmacognostic profiles including organoleptic characters (color, odor, taste, texture).
• Photographic documentation for future reference and education.

C. Phytochemical Standardization

• Qualitative and quantitative analysis of bioactive compounds using:
  • Thin Layer Chromatography (TLC)
  • High-Performance Thin Layer Chromatography (HPTLC)
  • High-Performance Liquid Chromatography (HPLC)
  • Gas Chromatography–Mass Spectrometry (GC–MS)
• Identification of marker compounds for each herb to establish a chemical fingerprint.
• Example:
  • Withania somnifera (Ashwagandha) – Marker: Withaferin A
  • Curcuma longa (Haldi) – Marker: Curcumin
  • Bacopa monnieri (Brahmi) – Marker: Bacoside A

D. Pharmacological and Toxicological Evaluation

• Assessment of safety and efficacy of raw materials through:
  • Acute and sub-chronic toxicity studies
  • Antioxidant, anti-inflammatory, and adaptogenic activity testing
• Helps determine whether collected herbs meet therapeutic potential as described in Ayurvedic classics.

E. Standardization Parameters Developed

Each herb studied under CCRAS is standardized on:

These parameters are submitted to PCIM&H for inclusion in the Ayurvedic Pharmacopoeia of India (API).

3. Key Initiatives by CCRAS

i. Raw Drug Repository (RDR) Network

• Serves as a national reference system for authenticated raw materials.
• Stores herbarium specimens, powder samples, and microscopy slides.
• Provides training to pharmacists, collectors, and manufacturers on raw drug authentication.

ii. Good Agricultural and Collection Practices (GACP)

• Training programs for farmers and tribal collectors to ensure:
  • Ethical harvesting of medicinal plants.
  • Avoidance of endangered species.
  • Maintenance of soil and ecological balance.
• Promotes traceability of raw drugs from cultivation to market.

iii. Digital Databases

• e-Charak Portal: Online repository and marketplace connecting cultivators, traders, and manufacturers.
• AYUSH Research Portal: Showcases research papers and data on standardized herbs.
• Medicinal Plant Species Atlas: Mapping of high-density medicinal flora zones across India.

6. Collaborations and Publications

• CCRAS collaborates with:
  • CSIR, ICMR, and DBT for advanced analytical and pharmacological studies.
  • Universities and AYUSH institutes for training and joint projects.
• Published volumes:
  • Pharmacognostic Studies on 200 Medicinal Plants
  • Atlas of Microscopy of Ayurvedic Crude Drugs
  • Standardization of Ayurvedic Formulations
  • General Guidelines for Drug Development of Ayurvedic Formulations (2023)
