AN EXPERIMENTAL EVALUATION OF ANTI-INFLAMMATORY ACTION OF ROOT OF APARAJITA (CLITORIA TERNATEA LINN.) IN ALBINO RATS

Plants have played a major role in the production of biological compounds for the formation of drugs. Their role may either become a base for the development of medicine, a natural blue print for the development of new drugs or a phytomedicine to be used for the treatment of diseases. Acharya Charaka has quoted that none of the plants found around us are non-medicinal. Clitoria ternatea commonly known as Aparajita or Butterfly pea is a medicinal plant belonging to the family Fabaceae. In various Ayurvedic classics and Ayurvedic material medica, this plant is reported to be used in insect bites, skin diseases, asthma, burning sensation, inflammation, leucoderma, leprosy and pulmonary tuberculosis.A good number of anti-inflammatory drugs are available in modern medicine, among them some are expensive and some are having adverse effects in long term uses. Thus a need arises to find a safer and efficient drug from the natural resources, which will be simple, effective and not having any adverse effect. In the present study, preliminary phytochemical study and anti-inflammatory study of Kashayam (decoction) of root of Aparajita were carried out to confirm the presence of various phytochemical substances and to determine the anti-inflammatory action against diclofenac sodium in carrageenan induced rat paw edema model. The results of experimental study showed significant anti-inflammatory action of Kashayam (decoction) of Aparajita roots in acute inflammation compared to control and near to the action of diclofenac sodium, which suggests that Aparajita is potential natural anti-inflammatory drug

Boosting Input Voltage and Improving PF Using PFC Circuit

Abstract -DC to DC converters are electronic devices used whenever we want to change DC electrical power efficiently from one voltage level to another. Electrical and electronic equipment is designed to operate on standard supply voltage .When the supply voltage is constantly too high or too low, the equipment fails to operate at maximum efficiency. So we need of boost converter to change the level of voltage from low to high in some applications. There are two types in boost converter. They are single boost and dual boost converter. We are applying same dc input voltage from bridge rectifier to both boost converters. Then we get different voltages for both boost converters from hardware model. But it should be Vo>Vi and dual boost output voltage should be greater than single boost output voltage. If a electrical device has a Power Factor is less than 1, that means more total input current must be supplied for a given output power dissipation and a more powerful source is required to deliver the required output power. So reducing lifetime of the device and its performance will not good. Hence, there is a continuous need for power factor improvement and reduction of line current harmonics. This work is carried out in MATLAB Simulink Environment. By measuring real power, reactive power and calculating apparent power, we get improved Power Factor and Total Harmonic Distortion of both single and dual boost converters using MATLAB Simulink Environment. The aim of this project to develop a circuit for Power Factor Correction by implementing two boost converters arranged in parallel to boost the input voltage, improve the PF of device and current quality for reducing current harmonics & switching losses
