Antioxidant and phytochemical properties of an ethanolic extracts from the wild edible mushroom Termitomyces reticulatus and their individual parts (Cap and Stipe) were evaluated. Reducing power, β-carotene bleaching, ABTS and DPPH radicals scavenging activity were used to evaluate their antioxidant activity. Antioxidant components like total phenol, flavonoid, β-carotene and lycopene were also determined and the amount of phenol was correlated with the antioxidant property. All the extracts showed potent antioxidant activities, in which the entire mushroom extract showed more antioxidant property when compared with the other two extracts (Cap and Stipe) and they were in the order, entire mushroom>stipe>cap. Total phenol exhibited a negative correlation with the EC50 values of antioxidant assays in all the extracts. The phytochemical profile of the ethanolic extracts, analysed were found to contain alkaloids, saponins, phenols, anthraquinones, steroids, carbohydrates, proteins and cardiac glycosides. The tannins and toxic content cynogenic glycosides were absent. In conclusion, our results supported the consumption of wild edible mushroom that act as a good dietary supplement, taken as whole or...

Paliperidone is a new active substance, belonging to the class of atypical antipsychotic, and is the active metabolite of a well-known active substance, risperidone that has been used for the last 3 years. A randomized, double-blind, multicentric, study to evaluate the safety and efficacy of Paliperidone ER compared to Olanzapine in patients with Schizophrenia was conducted in Indian schizophrenic patients. Pharmacokinetic Evaluation in Indian schizophrenic patients randomized to Paliperidone ER was an open label extension, pharmacokinetic (PK) study of previously conducted phase III trial. The doses of paliperidone 3, 6, 9, and 12 mg were administered during the study. Paliperidone concentrations were measured up to 36 hours post dose after administration of paliperidone ER 30 minutes after dinner to the patients who continued the medication after completion of phase III clinical trial. The mean Cmin, Cmax, AUC (tau) for paliperidone ER 3 mg, 6 mg, 9 mg, 12 mg were found to be [6.71 ng/ml, 23.59 ng/ml, 349.50 hr*ng/ml]; [28.88 ng/ml, 57.77 ng/ml, 1040.86 hr*ng/ml]; [17.25 ng/ml, 71.05 ng/ml,...

The purpose of this research was to develop fast disintegrating tablets of Salbutamol Sulphate using superdisintegrating agents. Recently fast disintegrating drug delivery system have started gaining popularity and acceptance as new drug delivery system, because they are easy to administer and lead to better patient compliance. Salbutamol Sulphate is a selective β2 receptor agonist widely used as a bronchodilator. It forms part of initial therapy of acute as well as chronic asthma. In present work an attempt has been made to formulate and evaluate fast disintegrating tablets of Salbutamol Sulphate. Ac-di-sol, Polyplasdone and Primojel were used as super disintegrating agents, while microcrystalline cellulose and mannitol were used as diluents. Direct compression technique was used as it requires conventional tablet machinery and thus economical process. Formulations containing Ac-di-sol as super disintegrating agent show rapid in-vitro and in-vivo dispersion time as compared to other...

The antioxidants such as quercetin and alpha- tocopherol were subjected for in vitro prophylactic cataract prevention study on glucose induced cataract model. Goat lenses were incubated in artificial aqueous humor containing 55 mM glucose with test drugs in different concentrations at room temperature for 72 h. Biochemical parameters studied in the lens were electrolytes (Na+, K+), Na+– K+– ATPase activity, malondialdehyde (MDA) and proteins. Glucose induced opacification of goat lens began 8-10 hrs after incubation and was complete in 72-80 hrs. Cataractous lenses showed higher Na+, MDA (P<0.001), lower Na+-K+– ATPase activity, and water-soluble protein content. Lenses treated with test drugs has shown higher protein content and prevented formation and progress of cataract by glucose, as evidenced by biochemical parameters....

Herbalism is a traditional medicine practice based on the utilization of plants and plant extracts. In herbalism ‘Valerian’ is a boon medicine for several ailments. Valerian (Valerian officinalis) is a naturally occurring Ayurvedic medicine widely grown in the temperate zones of Europe, North America and Asia and is a safe herbal supplement indicated in various ailments, chief being for the symptoms associated with difficulty in sleeping. It improves subjective experiences of sleep when taken nightly over one- to two-week periods. Although the adverse effect profile and tolerability of this herb are excellent, long-term safety studies are lacking. Due to the this limitations and inconsistent results in currently published clinical trials, further research is needed to clarify the efficacy and side effect profile of valerian, especially in regard to long-term therapy. In present investigation, the medicinally important herbal drug Valerian is reviewed for various taxonomical aspects including botanical authenticity, historical backgrounds, description, existing common names, medicinally important species, going through cultivation, commerce, regulation to phytochemical description, pharmacodynamics, pharmacokinetics, adverse drug...
