Seasonal fluctuations are periodical series, and have impact on availability of active principles in medicinal plants hence, therapeutic efficacy also get influenced. The survey of several scientific studies published in scientific journals of international repute indicates this fact. The studies reported that essential oil component shows a rhythmic increase in oil production throughout the growi...
A novel, simple, rapid and sensitive spectrophotometer method has been developed for simultaneous estimation of Lamivudine and Abacavir. The method employs formation and solving of simultaneous equation using 280 nm and 297 nm as two analytical wavelengths. Both the drugs obey Beer’s Law in the concentration ranges employed for this method. Accuracy and reproducibility of the proposed method was...
HYPOGLYCEMIC AND ANTIHYPERGLYCEMIC EFFECT OF ETHANOLIC EXTRACT OF WHOLE PLANT OF LAWSONIA INERMIS (HENNA) IN STREPTOZOTOCIN INDUCED DIABETIC RATS
Diabetes, a global burden, is characterized by fast elevation of blood sugar level. The incidence of diabetes mellitus is rising all over the world, especially in Asia. Many oral hypoglycemic agents, such as biguanides and sulphonylurea are available along with insulin for the treatment of diabetes mellitus but they have significant side effects and sometimes they are found to be ineffective in ch...
The nanoemulsion is one of the most efficient dispersed nanosystems of droplet size ranging to submicron size. Nanoemulsions/ Sub-micron emulsions (SMEs)/ Mini-emulsions are thermodynamically stable transparent or translucent dispersions of oil and water stabilized by an interfacial film of surfactant and co surfactant molecules having a droplet size of less than 100 nm. This review provides bri...
Air pollution tolerance index was assessed with plant species located at ChinnaTirupathi, Salem, Tamil Nadu, India. This study was conducted during March, 2013. Since, all the lands are converted to buildings, it is essential to know more about plants and its benefits offered to the environment and the dangers, risks caused by cutting trees. In this study, our aim is to evaluate, whether the plant...
EFFECT OF WATER STRESS BY POLYETHYLENE GLYCOL 6000 AND SODIUM CHLORIDE ON SEED GERMINATION AND SEEDLING GROWTH OF CASSIA ANGUSTIFOLIA
The impact of salt stress and water stress on seed germination, root and shoot length, fresh and dry biomass, vigour index was investigated in Senna (Cassia angustifolia) at germination stage (7DAS). Salinity stress was induced by using NaCl and drought stress by using PEG-6000. Different concentration of NaCl (0.1 to 100 mM) and PEG-6000(-0.1 bars to -2.0 bars) were used for seed treatment. The o...
The bioavailability of some orally administered botanical extracts is erratic and poor due to limited gastro-intestinal absorption. Bioavailability can be improved by using new delivery systems which can enhance the rate and the extent of solubilization into aqueous intestinal fluids and the capacity to cross biomembranes. Phospholipids based drug delivery system have been found promising for bett...
Background: Gouania longipetala Hemsl. (Rhamnaceae), has ethnomedicinal use in the treatment of wounds, gonorrhoea, abdominal pain, lumbago, ophthalmia, conjunctivitis, and rickets. However, no scientific investigation of these effects has been established. Our aim was to verify the antibacterial, antioxidant and anti-inflammatory effects of the stem of Gouania longipetala. Methods: The antibact...
STUDIES ON THE DISINTEGRANT PROPERTIES OF SEED POWDER, HUSK POWDER AND MUCILAGE OF PLANTAGO OVATA BY FORMULATION OF ORALLY DISINTEGRATING TABLET
Tablet disintegration has received considerable attention as an essential step in obtaining fast drug release. Disintegrating tablets are intended to dissolve or disintegrate rapidly in the mouth for which various natural and synthetic disintegrants are included in the formulation. The present work emphasis on the study of disintegrant property of mucilage, Husk powder and seed powder of Isapghula...
