Phytochemical screening and analysis of antimicrobial activities of different parts of eucalyptus globulus plant

Abstract

ABSTRACT newlinePHYTOCHEMICAL SCREENING AND ANALYSIS OF ANTIMICROBIAL ACTIVITIES OF DIFFERENT PARTS OF EUCALYPTUS GLOBULUS PLANT newline newlineThe thesis consists of four chapters, first chapter emphasized that in respect to the variety of biological activities of plants at the place among the others synthetic organic compounds. About 960 species of medicinal plants are estimated to be in trade of which 178 species have annual consumption levels in excess of 100 metric tons. The world herbal trade is expected to reach US$ 7 trillion by 2050, however, the Indian share in the world trade, at present is quite low. The history of herbal medicine provides decades, sometimes centuries, of anecdotal information, scientific study of herbal medicine is relatively new. The World Health Organization suggested that the medicinal plants would be the best source to obtain a variety of drugs. The herbal medicines utilizes a formula which consists of a complex mixture of multi components of different classes or plants. The composition of such formula appears to be optimized, since the components are not only additive but apparently synergistic in their bioactivity. Thus, it is necessary to understand how and why the herbs are combined as well as some general rules for combining herbs including the compatibility, contraindication, and dosage. newlineMedicinal plants have played a key role in world health. It is estimated that about 25 30% of all modern medicines are directly or indirectly derived from higher plants. The herbal products industry comprises a number of inter related sub sectors including as Herbal tears; Functional foods; Nutraceuticals; Phytochemicals; Ethical OTC medicines; Flavours and fragrances; Aroma therapy; Culinary herbs and Spices. The use of natural substance, particularly plants, to control diseases is centuries old practice that has lead to the discovery of more than half of all Modern pharmaceuticals. newlineConsidering the vast area of potentiality of plants as sources for drugs and taking into account the local traditional uses,
