ABSTRACT
High performance liquid chromatographic method was developed and validated for the determination of Darunavir Ethanolate in tablet dosage form. The method was carried out on a Phenomenex luna C18 Column (150 × 4.6 mm id, 5µ) maintained at 30oC. The mobile phase consisted of water-acetonitrile (60 + 40, v/v) pumped at a flow rate 1.0 mL/min. Photo diode array detection was at 265 nm. The chromatographic separation was obtained with a retention time of 11.8 min, and the method was linear in the range of 1-30 µg/mL (r2 = 0.9997). The specificity and stability indicating capability of the method was proven through forced degradation studies, which also showed that there was no interference of the excipients. The method was validated for linearity, precision, accuracy, robustness, specificity, limit of detection and limit of quantitation. The developed method, after being validated was successively applied to the analysis of tablet formulations. The drug could be effectively separated from different degradation products and hence the method can be used for stability analysis.

ABSTRACT
Fractionation of crude petroleum ether extract of the stem bark of Bauhinia variegata Linn (Caesalpiniaceae) led to the isolation of heptatricontan-12, 13-diol, friedelin, n-docosanoic acid, stigmasterol, β-sitosteryl, n-hexadecanoic acid, lupeol. Eriodictyol & Quercetin were isolated from methanolic extract. Their structures were elucidated by spectroscopic methods such as UV, IR, 1H NMR and MASS. Eriodictyol was isolated for the first time from this plant.

ABSTRACT
Good Clinical Practice (GCP) is an international ethical and scientific quality standard designed to conduct, performance, monitor, audit, record, analyse and report clinical trials. It protects the rights, integrity and confidentiality of trial subjects. Clinical research trails are increasingly playing a role in various medical disciplines.  GCP guidelines are used in clinical trials through out the globe with the main aim of protecting and preserving human rights. In this review article the historical background and the events that led up to the formation of these guidelines, key trial activities and principles of GCP are discussed.

ABSTRACT
Ayurvedic plants have shown their effects on various kind of diseases. Those properties of the plants are sublimed in some molecules in the plants, which can be extracted out by performing various kind of processes (eg. Soxhlation, Percolation). Many plants which are used by the human being in daily life, also have some effects in curing some disease conditions. Likewise in our current review Aegle marmelos (Beal) have Antidiarrhoeal, Antidiabetic activities etc. Many Pharmacological Activities have been revealed & organized in this review article, but there have a wide scope of research to perform on this plant.

ABSTRACT
The aim of the present work was to enhancement of Solubility and Dissolution of Clozapine using liquisolid technique. This work aimed to study the effect of different liquid vehicles on release characteristics of Clozapine. For liquisolid technique, different amount of liquid and ratio of carrier to coating material were employed. Avicel PH 102 and Aerosil 200 were used as carrier and coating material respectively and sodium starch glycolate (5%) was used as superdisintegrant. The empirical method as introduced by Spireas and Bolton 1999 was applied strictly to calculate amount of carrier and coating materials required to prepare liquisolid tablet. Quality control test like uniformity of tablet weight, uniformity of drug content, hardness, friability test, disintegration test and in-vitro dissolution tests were performed to evaluate the each batch of prepared tablets. In vitro drug dissolution profile of the liquisolid formulation were studied and compared with the Directly Compressed tablet of Clozapine in 0.1N HCL. Stability study was carried out to evaluate the stability of the tablet under humid condition. It was found to be that the optimized liquisolid tablet has high dissolution efficiency (80.44%) and lower mean dissolution time (MDT).From present study it can be concluded that liquisolid technique shows better improvement in solubility and dissolution of Clozapine than the pure drug.

ABSTRACT
Methanol, chloroform, petroleum ether and aqueous extract of Crotalaria burhia (whole plant) were investigated for their antibacterial activity against Staphylococcus aureus using cup plate agar diffusion method. The 4 extracts tested, the methanol extract presented the best results. Various investigations like physicochemical standards, preliminary phytochemical screening of the plant was carried out, and the salient qualitative parameters were reported. The present paper deals with the investigation of various photochemical present in various extract and in vitro antibacterial activity. It is concluded that the plant studied may be a source of antibacterial agent.

ABSTRACT
Depression and related mood disorders are among the world’s greatest public health problems. Mimosa pudica L. (MP), a creeping perennial herb exhibits analgesic, anxiolytic, diuretic, antiasthmatic, hepatoprotective activities. Although, previous study reveal antidepressant like effects of aqueous extract of MP at behavioral levels, but antidepressant like effects of hydroalcoholic extract of Mimosa pudica L. (HEMP) and its combinational effect with standard antidepressant drugs at behavioral and biochemical level is not scientifically evaluated. Hence, the present investigation evaluates the antidepressant activity of HEMP and its interaction with fluoxetine and imipramine in reserpine-induced behavioural despair in rats and the potential mechanism involved in HEMP action. HEMP at doses 50, 100 and 200 mg/kg p.o., fluoxetine at 5 & 20mg/kg p.o., imipramine at 5 & 15mg/kg p.o. and reserpine 6mg/kg i.p. were administered to different groups of rat (n=6). After reserpine treatment, rats were subjected to forced swimming test followed by assessment of locomotor activity. Rats were sacrificed after behavioural study for estimation of serotonin, monoamine oxidase (MAO) levels in rat brain. Results demonstrate that combination of subeffective doses of HEMP, fluoxetine and imipramine reduced the duration of immobility in forced swimming test, increased serotonin and decreased MAO-A and MAO-B enzyme levels in reserpine treated rats. These findings suggest that combination of HEMP with standard drugs in subeffective doses can exert potential antidepressant like effect through modulation of brain serotonergic system and MAO inhibition.

ABSTRACT:
A natural substance that acts to control plant activities are Plant growth regulators and often called phytohormones to regulate growth, development and responses to stimuli. Which includes hormones and non-nutrient chemicals not found naturally in plants that when applied in plants, influence their growth and development. Changes in phytohormone levels result in gene activation shifts. This paper accomplishes the review article on chemistry of the novel plant growth regulators according to their medications, and has been discussed according to the types of plant growth regulators.

ABSTRACT:
Colorectal is the third most prevalent form of cancer in the world. Several studies report that prostaglandins are mediators of carcinogenesis cyclooxygenase known as prostaglandin endoperoxidase H synthase. Levels of COX-2 isoenzyme and prostaglandins like PGE2, PGF2 alpha and PGE1 are found to be higher in certain cancers like colorectal carcinoma, squamous cell carcinoma of head and neck, also in certain types of breast cancer. Prostaglandins may contribute to the cancer processes through one or more of several mechanism including increased proliferation, apoptosis, inhanced carcinogen metabolism of immune system. Decreasing the high level of COX-2 and prostaglandins already mentioned has shown to decrease carcinogenesis. The understanding of the regulation of substrate availability and of a regulation (Dysregulation in many neoplasis) of the synthesis enzymes has opened avenues leading to design of isoenzyme specific inhibitors and better cancer strategies.
