Abstract
Objective: Classical polyherbal preparations in Ilmul Advia (such as Majun Dabeed-ul-Ward, Jawarish Shahi, and Khamira Gaozaban) exhibit profound clinical utility as hepatoprotective, cardiotonic, and neuro-rejuvenating agents. However, the lack of standardized chromatographic fingerprints and quantitative marker assays has hindered global regulatory acceptance. This research establishes rigorous physicochemical, HPTLC, and heavy metal specifications for three major compound formulations.
Methods: Authentic botanical constituents were verified via macroscopic, microscopic, and DNA barcoding assays. Hydro-methanolic extracts underwent High-Performance Thin-Layer Chromatography (HPTLC) using optimized solvent systems (Toluene : Ethyl Acetate : Formic Acid, 5:4:1 v/v) scanned at 254 nm and 366 nm. Heavy metals (Lead, Cadmium, Arsenic, Mercury) were quantified via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) in compliance with WHO thresholds.
Results: Reproducible chromatographic fingerprints yielded distinctive Rf values for marker constituents including gallic acid (Rf 0.42), glycyrrhizin (Rf 0.31), and luteolin (Rf 0.68). ICP-MS confirmed heavy metal levels significantly below permissible limits (Pb < 2.1 ppm, Cd < 0.12 ppm, As < 0.85 ppm, Hg < 0.04 ppm). Microbial counts and aflatoxin B1/B2/G1/G2 levels remained below limits of detection.
Conclusion: These established chromatographic fingerprints and elemental profiles provide reliable monographs for quality surveillance, preventing adulteration and supporting the commercial export of Unani formulations to global markets.
1. Introduction
The discipline of Ilmul Advia (Unani Pharmacology and Materia Medica) encompasses thousands of single drugs (*Mufradat*) and compound formulations (*Murakkabat*) categorized according to their innate temperament (*Mizaj-e-Advia*) and degrees of action (1st to 4th degree) [1]. Formulations such as *Majun*, *Jawarish*, *Khamira*, and *Sharbat* represent sophisticated pharmaceutical combinations designed to optimize bioavailability, neutralize potential side effects through corrective agents (*Muslih*), and target specific organ systems (*Badal*) [2].
However, international quality regulations—including the United States FDA Dietary Supplement Health and Education Act (DSHEA), European Medicines Agency (EMA) herbal directives, and GCC registration guidelines—mandate definitive chemical characterization, batch-to-batch consistency, and validated safety margins [3, 4]. The objective of this multicentric investigation is to provide chromatographic and spectroscopic reference standards for three sentinel Unani preparations.
2. Materials & Methods
Collection & Authentication: Raw botanical ingredients—including *Rosa damascena* (Gul-e-Surkh), *Crocus sativus* (Za'fran), *Pistacia lentiscus* (Mastagi), and *Terminalia chebula* (Halela)—were procured from certified cultivators and authenticated by the Pharmacognosy Herbarium of the Regional Research Institute of Unani Medicine (RRIUM), Srinagar [5].
Extraction & Sample Preparation: Formulations were prepared according to the National Formulary of Unani Medicine (NFUM) Part I. For chromatographic assay, 5.0 g of each sample was extracted with 50 mL methanol under reflux for 2 hours, filtered through 0.45 μm PTFE membranes, and concentrated under vacuum at 40°C.
Instrumentation: HPTLC was performed using a CAMAG Linomat 5 automatic sample applicator on pre-coated silica gel 60 F254 aluminum plates (Merck, 20 × 10 cm). Elemental quantification of Lead (Pb), Cadmium (Cd), Arsenic (As), and Mercury (Hg) was executed using an Agilent 7900 ICP-MS system following microwave-assisted digestion with nitric acid and hydrogen peroxide [6].
3. Results & Analytical Findings
The HPTLC densitometric scanning revealed clear, well-resolved bands across all batches tested. The chromatographic profile for *Majun Dabeed-ul-Ward* exhibited 9 distinct peaks under UV 254 nm and 12 fluorescent bands under UV 366 nm after derivatization with anisaldehyde-sulfuric acid reagent.
| Analytical Parameter | Majun Dabeed-ul-Ward | Jawarish Shahi | Khamira Gaozaban | WHO Permissible Limit |
|---|---|---|---|---|
| Total Ash (% w/w) | 2.45 ± 0.12 | 1.82 ± 0.08 | 1.25 ± 0.05 | NMT 5.0% |
| Acid-Insoluble Ash (% w/w) | 0.38 ± 0.04 | 0.22 ± 0.02 | 0.15 ± 0.01 | NMT 1.0% |
| Alcohol-Soluble Extractive (%) | 28.4 ± 1.1 | 32.6 ± 1.4 | 36.8 ± 1.2 | NLT 20.0% |
| Lead (Pb, ppm) | 1.84 ± 0.15 | 1.42 ± 0.11 | 0.98 ± 0.08 | NMT 10.0 ppm |
| Cadmium (Cd, ppm) | 0.08 ± 0.01 | 0.06 ± 0.01 | 0.04 ± 0.005 | NMT 0.3 ppm |
| Arsenic (As, ppm) | 0.62 ± 0.07 | 0.45 ± 0.05 | 0.31 ± 0.03 | NMT 3.0 ppm |
| Mercury (Hg, ppm) | 0.02 ± 0.004 | 0.03 ± 0.005 | 0.01 ± 0.002 | NMT 1.0 ppm |
4. Discussion & Regulatory Implications
The rigorous consistency documented across three independent production batches establishes that classical Unani pharmaceutical methods—when conducted under Good Manufacturing Practice (GMP) conditions—yield products that fully comply with modern toxicological standards [7]. The trace elemental concentrations observed fall well within European Pharmacopoeia and United States Pharmacopeia thresholds.
Importantly, the identification of marker phytochemicals such as gallic acid and quercetin provides actionable quantitative metrics for manufacturers. Rather than relying on simple dry weight yields, regulatory dossiers can now utilize validated chromatographic fingerprints to demonstrate identity, purity, and batch concordance [8].
5. Conclusion
This study provides empirical baseline monographs for three cardinal polyherbal formulations of Ilmul Advia. By demonstrating the compatibility of traditional pharmaceutical heritage with state-of-the-art analytical chemistry (HPTLC and ICP-MS), these findings lay the groundwork for expanded pharmacopoeial monographs and facilitate the international commercialization of evidence-based Unani pharmaceuticals.
