2º alcohols under acidic conditions (such as sulphuric acid) undergo degradation into E & Z isomers. There are many drug substances with sulphate as salt, and sulphuric acid is used for the preparation of sulphate of drug substance. Also, sulphuric acid is widely used in synthetic process for many drug substances. 2º alcohols are widely used as process solvents and as crystallization solvents. Loss of solvents is very high, when 2º alcohols used as crystallization solvent and drug substance will have high crystalline stability. Flash points of 2º alcohols are comparatively higher than other solvents such as methanol, ethanol, benzene, dichloromethane and many other volatile solvents resulting into better fire safety for reactions and also lower exposure limits. Residual odour while drying of drug substance is minimum. 2º alcohols possess very low practical handling difficulties. For all these reasons, 2º alcohols are the preferred choice as process solvents and crystallization solvent. However and unfortunately when these 2º alcohols and sulphuric acids used together in a reaction, 2º alcohols undergo...

Fertility control is an issue of global challenge. Researchers are trying to develop male herbal contraceptives from natural sources. Jussiaea repens L (JR) is such an herb which is reported to have non toxic antigonadal activity in male rats. The present study has designed to evaluate whether crude queous extract of JR affects the DNA integrity of spermatozoa and also to study whether its actions are reversible or not. In this study, toluidine blue (TB), acridine orange (AO) and aniline blue (AB) staining were used to assess sperm chromatin / DNA integrity and comet assay for sperm DNA damage. Results show that the DNA integrity or denaturation by TB, AO and AB positive staining of spermatozoa of JR treated group were significantly increased when compared with control. But TB positive staining was much higher (34.51%) than AO (27.06 %) and AB (18.91%) positive staining. But no denaturation was observed in epididymal spermatozoa of rats after withdrawal of extract treatment. Results of Comet assay also support the reduced change in...

The preliminary phytochemical evaluation and effect of Honey on Hematological parameters were investigated. Preliminary phytochemical screening was carried out to determine the presence of various bioactive constituents through different Tests. The Antimicrobial study of different Honey in combination with synergistics was carried out on selective microorganisms through well diffusion method. The effect of Honey on hemoglobin, WBC, Blood Sugar and weight loss was studied on swiss albino male mice under controlled conditions for 21 days. The Highest percentage of coumarins (+++), Resins (+++) were found in all the types of tested Honey among the different phytochemicals Screened. However the absence of carboxylic carbon and tannins were noticed during the study. The antimicrobial studies along with different synergistics shown significant results like Natural Omani Honey exerted 36mm zone of inhibition against S.aureus, while Turkish honey found to be more antimicrobial against P. aeruginosa (40mm). In the present study on Hematological and physiological parameters it was observed that increase in WBC % with greatest significance, among all the tested Honey with...

The nutritional supplements are the natural food supplements, and other related products used to boost the nutritional content of the diet. These nutritional supplements have been of interest to research because of their antioxidant property by consumption of food and drinks. The present study deals with a comparative evaluation of antioxidant and anti-inflammatory effects of marketed nutritional supplements using cytoprotection, lipidperoxdiation and membrane stabilization activities on RBC under in-vitro condition. The marketed nutritional supplements exhibited cytoprotection or prevented hemolysis in erythrocytes and provided better protection against H2O2 induced oxidation and lipid peroxidation and exhibited good membrane stabilization when compared to standard. The Women Horlicks showed significant protection against H2O2 induced cytotoxicity in erythrocytes when compared to other supplements, the nutritional supplement Boost provided better protection against lipidperoxidation induced by H2O2 in erythrocytes. The nutritional supplement Maltova showed better membrane stabilization activity when compared to standard and other nutritional...

The antidyslipidemic and antioxidant activities of Allium sativum (Garlic) and Aloe vera (Ghee- kuwar) extracts have been studied in two models of hyperlipidemia, triton and cholesterol rich high fat diet induced hyperlipidemia. A. sativum, A. vera and Gemfibrogil were macerated with 0.2% aqueous gum acacia and the suspension was fed orally to rats of group III, IV and V at a dose of 400mg, 1g/Kg, and 50 mg/Kg (b.w.p.o.) respectively with triton. Serum lipids were found to be lowered by Allium sativum and Aloe-vera in triton induced hyperlipidemia. On the other hand chronic feeding of these extracts to animals in cholesterol rich high fat diet induced hyperlipidemia for 30 days caused lowering in lipid and protein levels of β lipoproteins followed by an increase in α lipoproteins. The results of present study demonstrate that hypolipidemic activity of these extracts mediate through inhibition of hepatic lipid synthesis, increased faecal bile acid excretion and induced plasma LCAT activity in rats. Furthermore these extracts (100 and 200 µg/ml) inhibited the in vitro...
