Depression is a heterogeneous disorder that affects a person’s mood, physical health and behaviour. Despite progress in pharmacotherapy, in majority of patients depression goes undiagnosed and untreated. Ayurveda, the Indian traditional system of medicine, mentions a number of single and compound drug formulations of plant origin that are used in the treatment of psychiatric disorders. Tribulus terrestris (Gokshura) is used in Indian and Chinese system of medicine for treating various male reproductive disorders. The present study was undertaken to evaluate the antidepressant potential of acute and chronic administration of Tribulus terrestris in forced swim test (FST) and tail suspension test (TST). Inbred Swiss Albino mice weighing 20-30g were used in the study. The vehicle distilled water ( (10ml/kg, p.o), imipramine (20mg/kg, p.o) and Tribulus terrestris  (100mg/kg, 200mg/kg, 400mg/kg, p.o. respectively) were administered 1hour prior to acute study. In chronic study, all drugs were given once a day for 10 days and the last dose was given 1hour before the experiment. Duration of immobility was noted in both the models. In our study, both imipramine and Tribulus terrestris significantly reduced the duration of immobility in both experimental models as compared to the animals in the control group. The antidepressant activity of Tribulus terrestris was comparable to that of standard drug imipramine. The results of the present study showed significant antidepressant activity of Tribulus terrestrisin animal models of depression

In the recent years, scientific and technological advancements have been made in the research and development of novel drug delivery systems by overcoming physiological troubles such as short gastric residence times and unpredictable gastric emptying times. Several approaches are currently utilized in the prolongation of the gastric residence times, including floating drug delivery systems, swelling and expanding systems, polymeric bioadhesive systems, modified-shape systems, high-density systems and other delayed gastric emptying devices. This review entitled the detailed scenario related to Bilayer floating drug delivery system with their advantages over the conventional drug delivery system and also limitation, which are helpful in development of dosages form. Various types of techniques employed for development of this dosages form. Review focused on formulation aspect of effervescent floating drug delivery system with their evaluation techniques. The purpose of this comprehensive review is to compile the work going on this delivery system. Which provide the valuable information related to formulation aspect to achieve gastric retention and discussed the various factors affect and to overcome it

  In the present communication, finger print of two ethano-botanically important Anisomeles species has been developed. A sensitive and reliable densitometric High Performance Thin Layer Chromatography (HPTLC) method has been developed for the quantification of quercetin, β-sitosterol, stigmasterol, catechin and ovatodiolide present in Anisomeles indica and Anisomeles malabarica.  Chromatographic analysis was performed using methanol, chloroform, acetone and ethanol extract of these plants were developed in the different solvents such as toluene, chloroform, ethyl acetate, methanol at various proportions. Detection and quantification of all phytoconstituents was done by densitometric scanning at different wavelengths. These finger prints would be helpful in the standardization of these species.   Key words: HPTLC, Anisomeles indica, Anisomeles malabarica, phytoconstituents, standardization
