The focus is to make the process cost-effective and fruitful with higher productivity. Materials and Methods: Adaptive strain development was carried out so that the P. rhodozyma can give the best astaxanthin at a higher temperature (35°C), increasing the process economy. P. rhodozyma was cultivated with three broad spectrum antibacterial drugs - streptomycin, gentamycin, and ampicillin (200 μL) and with antifungal drug - fluconazole (200 μL) to determine the effect on yeast growth and astaxanthin production. Rice, cane juice, and sucrose were selected as carbon source and compared with dextrose at different fermentation temperatures - 22°C, 30°C, 33°C, and 35°C for astaxanthin production. Results: P. rhodozyma was resistant to antibiotic drugs inhibiting bacterial and fungal contaminants. Rice being more economical was selected as carbon source, but the strain was not able to utilize starch-rich substrate leading to its rejection. When P. rhodozyma was grown in cane juice, biomass is highest (OD 2.77) at 30°C and 610 nm wavelength, whereas astaxanthin productivity is highest (OD 2.64) in dextrose media at 30°C and 450 nm. Comparative metabolic and growth results for UV mutants showed significantly higher biomass and astaxanthin productivity in comparison to wild strain. Conclusion: The most efficient carbon source in terms of penny-pinching and astaxanthin productivity was found to be dextrose containing media at 30°C.","PeriodicalId":11347,"journal":{"name":"Drug Development and Therapeutics","volume":"54 5 1","pages":"63 - 68"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85046952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Manufacture of these medicines to meet this increasing demand has resulted in a decline in their quality, primarily due to a lack of adequate regulations pertaining to this sector of medicine. Hence, it is necessary to come up with a systematic approach to develop well-designed methodologies for the standardization of polyherbal formulations which are used in traditional systems of medicine. Materials and Methods: Qurs-e-Hummaz formulations were prepared by a qualified “Hakim” (Unani medical practitioner) of Faculty of Unani Medicine, Hamdard University, as per the formula and instruction given in National Formulary of Unani Medicine. Results: Various quality control parameters such as organoleptic evaluations (color, odor, taste, and consistency), physicochemical evaluations (loss on drying, disintegration time, moisture content, total ash, acid insoluble ash, water soluble ash, pH of 1 and 10% solution, extractive values, water soluble matter, alcohol-soluble matter, and total phenolic content) and thin layer chromatography fingerprint profiling have been carried out in triplicate. The evaluation of contaminants such as heavy metals, aflatoxins, pesticide residues, and microbial contamination has also been carried out in the formulation.

Since then, many Arab and Persian scholars have contributed to the system. Among them, Ibn-e-Sina, an Arab philosopher and Physicist, who wrote “Kitab-al-shifa” are worth mentioning. This system has an extensive and inspiring record in India. Khamira Abresham Hakim Arshad Wala (KAHAW) and Khamira Marwareed (KM) are semisolid sugar-based preparations with potent cardiac tonic and well-known antioxidant properties. It has been studied that therapeutic intervention of KAHAW may be used to prevent or to decrease the deterioration of cognitive function and neurobehavioral activities, often associated with the generation of a free radical. However, no considerable attempt has been made for quality evaluation of KAHAW. Materials and Methods: In the present investigations, KAHAW and KM were evaluated for their phytochemical screening, physicochemical standards, presence of minerals, contaminants such as aflatoxins, pesticide residues, thin layer chromatography, and high performance thin layer chromatography (HPTLC) as per WHO and AYUSH guidelines for development of quality standards, which can be used by Unani industries. Results: Physicochemical parameters of the prepared compound formulation KAHAW and KM were studied such as total ash, acid insoluble ash, water soluble ash, solubility matter in alcohol and water, and loss on drying at 105°C, pH as per the methods described in WHO guidelines. The heavy metal, aflatoxins, and pesticide residues were also determined for safety evaluation. The total phenolic and flavonoid contents were estimated using catechin and quercetin as standard after preparing calibration plot, respectively. HPTLC fingerprinting of hydrolyzed chloroform extracts of KAHAW and KM was carried out to determined a number of spots present in them. Conclusions: This study on pharmacognostical standardization of KAHAW and KM will provide useful information for its identification and quality control and can be applied by different manufacturers of these formulations.","PeriodicalId":11347,"journal":{"name":"Drug Development and Therapeutics","volume":"344 1","pages":"47 - 50"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79607886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Till date, there is no treatment for psoriasis except some herbal drugs and its constituents. Since Ayurveda is the main traditional system of medicine in India, here, we have selected one ayurvedic formulation - Lajjalu Keram, which has been used since long for their quality control. Methods: Total microbial load of formulations were carried out for total fungal count and total bacterial count. Lajjalu Keram was also tested by high-performance liquid chromatographic (HPLC) for aflatoxins (B1, B2, G1, and G2), which showed its presence below the permissible limit; similarly, pesticides residues were analyzed using gas chromatography/mass spectrometry for organophosphates and organochlorides, which showed that pesticides were below detection limit (0.1 ppb). The content of heavy metals was analyzed using AAS, which demonstrated the presence of cadmium, lead, and arsenic below permissible limit, whereas mercury was found absent. Results: The result of quality control analysis showed the presence of alkaloids, tannins, carbohydrate, saponins, proteins and amino acids, lipid/fats, phenolic compounds, and flavonoids in formulation. The dermal toxicity (LD50) of Lajjalu Keram in Wistar rats was found more than 2000 mg/kg (safe for the management of psoriasis). Formulation was also analyzed for their composition of fatty acids. It was found to have 13 fatty acids, out of which, seven were saturated fatty acids (95.2%) and the rest were unsaturated fatty acids (3.27%). A rapid HPLC method for quantification of mimosine (an unusual amino acid present in formulation) has been developed and validated. The mimosine content in Lajjalu Keram was found to be 0.0070% w/w with % relative standard deviation of 0.41. Conclusion: The formulation afforded significant and better protection of carrageenan-induced rat paw edema (72.11% inhibition) as compared to control. The shelf life studies on antipsoriatic herbal formulations were carried out for 6 months at different time intervals. No significant variation in analysis parameters was observed on the storage of formulations up to 6 months. The assay of constituents using mean curve of sigma plot showed 44.2 month of shelf life for Lajjalu Keram.","PeriodicalId":11347,"journal":{"name":"Drug Development and Therapeutics","volume":"1 1","pages":"43 - 46"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84589191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
