ABSTRACT:

Since the time Hippocrates man has made the use the different Unani medicines for the treatment of various ailments and still vast majority of population depends on these drugs. So the herbal drugs are gaining more and more attention all over the world due to their long historical clinical practice and less side effects. “Qurs- e- Zarishk” is one of the most important poly-pharmaceutical Unani formulation widely used for the treatment of liver disorders and anemia. Since the formulation has a very effective role in curing such diseases with zero side effects (unlike in Modern Medicine) so all the ingredients used in this preparation are required to be authenticated and standardized properly for quality control purposes. The present paper deals with different physicochemical and biological parameters like botanical identification, microbial load, aflatoxin, pesticide residue, determination of heavy metals, qualitative and quantitative analysis of phyto-chemical constituents, solubility in alcohol and water, successive extractions, pH values, ash values, quantitative estimation of total phenolics, resins etc. Besides, TLC studies of successive extracts have also been carried out.

INTRODUCTION:

India has a rich heritage of traditional medicine constituting with its different components like Ayurveda, Siddha, Unani, Homoeopathy and naturopathy. Traditional health care has been flourishing in this country for many years (Mukherjee, P. K, 2003). In Unani System of Medicine, single drugs (plant, mineral and animal origin) as well as compound drugs are being used for the treatment of various ailments by the exponents of these Systems. In the past decade, there has been renewed attention and interest in the use of traditional medicine globally. Though the Unani formulations are gaining global acceptance due to their amazing clinical efficiency, their quality control and standardization remains an unexplored issue. In the modern system, there is often no complete cure for various diseases and the drugs have many side effects. Hence, the attention of masses is diverting towards the indigenous systems which are quite safe with no side effects. Hence, the concept of standardization is becoming essential as a means of ensuring a consistent supply of high-quality traditional phyto-pharmaceutical products (Shailajan, S. et al; 2011) 

 

Qurs-e-Zarishk is a well-known, phyto-pharmaceutical product widely used for the treatment of liver disorders and anemia. This drug consist of several important single drugs like Zarishk, Rewand chini, Tukhm-e-Kasni which have a very high medicinal value in the treatment of liver diseases. The combination of these drugs enhances the efficacy of the compound formulation “Qurs-e-Zarishk”. Keeping in view the importance of this formulation and in order to have uniform quality as well as batch to batch consistency, there is an urgent need to have some standards for quality control and standardization of this formulation.

 

MATERIAL AND METHODS:

All the raw drugs present in the formulation were procured from the different raw drug dealers from Delhi and authenticated as per Pharmacopoeial and other official standards (API and UPI). The drug was prepared in different batches at laboratory scale as per ingredients composition and guidelines NFUM part I (Anonymous, 1982) and Bayaz-e-Kabir Part II (Hakim Kabiruddin) following the Standard Operative Proceedures (SOP). All the ingredients of samples are preserved in the Drug Standardization Research Unit New Delhi.

 

For preparation the drug, take all the ingredients of pharmacopoeial quality. Dry the ingredient no. 1 on low fire and grind ingredient no. 4 separately.

RESULTS AND DISCUSSION:

The chemical compounds may be responsible for the therapeutic efficacy of that drug. Phytochemical screening of the chemical constituents (Overtone, et al., 1963) present in the drug revealed that it contains glycosides, steroids, phenolic, tannins, resins, proteins, flavonoids and amino acids while the saponins was found to be negative. These phyto-constituents so obtained during the analysis has been shown in Table no. 3. In quantitative estimation for physico-chemical parameters three experiments were conducted for each sample and their % mean values of total phenolics, tannins, resins and alkaloids are mentioned in Table no. 4. The solubility and extractive values sometimes are used as an index of purity for formulations. Therefore, for establishing the standards of any drug, these extractive values and solubility play an important role These physico- are considered as tools of checking the quality, identity, purity and strength of Unani drugs as the adulterated or exhausted drug material will give different values rather than the extractive percentage of the genuine one (Jerkins et al.,1967). Quantitative standards revealed that the loss of weight on drying obtained in the drug was 3.5-4.5% shows the amount of moisture content present in the drug. Estimation of ash values are an important criterion for judging the impurities along with identity and quality of the drugs because adulteration of herbal drugs with unwanted materials like earthy matters resulting in higher ash percentage. Estimation of ash values are an important criterion for judging the impurities along with identity and quality of the drugs because adulteration of herbal drugs with unwanted materials like earthy matters resulting in higher ash percentage. The values of the total ash and acid insoluble ash were 6.39-7.10% and 3.15-3.40% respectively which indicate that the amount of mineral matter present in the drug. Water soluble extractives 38.68%, indicates the presence of inorganic content while alcoholic soluble extractives 35.53% indicates the extraction of polar constituents. The pH values of all three samples were found to be acidic. The study was extended for the successive extraction in different solvents as per increasing orders of their polarities are given in table no. 5 and chromatographic profile of these extracts can be seen in table no. 11. In quality control parameters the bacterial load and total fungal count of microbial studies, aflatoxin, heavy metals and pesticide residues were either within the permissible limits or found to be absent as shown in Table no. 7, 8, 9 and 10 respectively. At the same time bacteria Enterobacteriaceae, Salmonella spp, Escherichia coli, Staphylococcus aureus, were found to be absent which shows that the drug is not the carrier of these organisms. TLC profile of successive extracts petroleum ether, chloroform and ethanol can be seen in table no. 11.

 

CONCLUSION:

The results of all the biological and physico-chemical studies presented here will be useful not only for monitoring the purity and quality of the drug but also check adulteration in raw material as well. Besides, the data regarding the macro and microscopic studies of ingredients particularly plant based drugs further helps in authentication of the product.

 

The evaluated data such as powder microscopy, physicochemical, TLC and analysis of quality control parameters indicate that the genuine raw drugs were added in the formulation and there is no variation in the batch to batch consistency of the drug. The quality control study revealed the absence of microbial load, heavy metals, aflatoxins and pesticide residue which shows the non-toxic effect of the drug. The evaluated standards will be much useful for laying down the pharmacopoeial standards of Qurs-e-Zarishk and also the providing the quality medicine to the needy mass. From the present studt it can be concluded that the formulation Qurs-e-Zarishk is quite safe, effective and affordable drug.
