Phytochemical investigation and comparative pharmacological Screening (viz, hepatoprotective, anti ulcer, diuretic and Antioxidant activity) of ethanol extract of Cucumis sativus Linn.and Trichosanthes cucumerina Linn. with Coriander formulation.

INTRODUCTION : India has a rich legacy of deep-rooted medicine constituting with its different gears like Ayurveda, unani, homoeopathy siddha and Naturopathy. All the above components based upon the herbs as a medicine. Traditional health care has been successful in this country for many centuries. In India around 20,000 medicinal plant species have been recorded recently, but more than 500 traditional plants use for curing most of the diseases. Herbal constituents are the medicinal products which contain mixture of compounds obtained from plant materials as their pharmacologically active components. These generally consist of complex mixtures of one or more plants and plant materials. The entire plant material contains plant materials viz., leaves, seeds, stems, wood, bark, flowers, fruits, roots, rhizomes, resins , gums and essential oils, etc. Plants have provided to mankind a large variety of potent drugs to ease relief from diseases. In spite of amazing advances in synthetic drugs in couple of years, some of the drugs from plant origin have still retained their magnitude. The use of plant based drugs of the world is growing and this is because of the faith that many herbal medicines are free from side effect. AIM AND OBJECTIVES : The growth of fast and precise analytical methodology and the preparation of purified analytical and experimental standards for the analysis of plant phytochemical is a key part of the new research effort aimed at unlocking the mode of action of phytochemical in both plant and animal systems. Often, these compounds are found very low concentration in the plants. They may be accumulated only under certain condition, such as the growth of reproductive structures or under specific types of stress. Accurate analytical methodology, in collaboration with accurate biological studies is required, to determine the effect of these compounds on health. So, there is emerging to have a research and development in the field of medicinal plants has acquired a considerable importance. 1. Due to increasing in the scope and demand of herbal drugs, especially in disease like liver, cancer, diabetes, ulcer, diarrhea, arthritis and skin disease etc. Hence It’s planned here to study the plants like Trichosanthes cucumerina L. (EETC), Cucumis sativus L. (EECS) and Coriandrum sativum L. (EECRS) for phytochemical investigation and develop a poly herbal formulation and their pharmacological studies. 2. The selected plants for the present study were based on its easy availability, degree of research work which is not done in a particular area. 3. The literature survey revealed that very less amount of hepato productive and anti ulcer studies has been carried out to the leaves of Trichosanthes cucumerina L. and Cucumis sativus L. 4. Therefore, it was thought valuable to carry out preliminary phytochemical screening (By chemical test), isolation of some compounds and characterization of isolated compounds (by IR, NMR and Mass analysis) the comparative pharmacological screening ring of ethanol extracts of leaves of Trichosanthes cucumerina L., Cucumis sativus L. and their formulation with Coriandrum sativum L. fruit viz. hepatoprotective, diuretic, antiulcer and antioxidant activity. The plant extracts shows considerable report in pharmacological screening hence it planned to formulate herbal tablet formulation. The extracts of the three plants shows hepatoprotective , diuretic and antioxidant activity. Except Coriander other two plants showed antiulcer activity. Hence for hepatoprotective and diuretic activity all the three plants are used to prepare tablet and named as polyherbal formulation (PHF), for Antiulcer and Antioxidant activity only EETC and EECS are used and named as herbal formulation (HF). 5. The main focal point of this study was hepatoproductive and antiulcer activity with new herbal formulation and in isolated compounds. MATERIALS AND METHODS : Fresh leaves of Trichosanthes cucumerina L., Cucumis sativus L. and fruits of Coriandrum sativum L. were collected from field of Komarapalayam and authenticated by Dr.P. Satyanarayana, Scientist D & Head office in charge, Southern Regional Centre, TNAU campus, Coimbatore. Voucher specimen (No: J.K.KNCP/0102/12, 13and 14) has been deposited in the Department of Pharmacognosy, J.K.K Nataraja College of Pharmacy, Komarapalayam, Tamilnadu, India The fruits of Corriandrum sativum L. were dried and then crushed into fine powder by using laboratory Homogenizer then stored for further use. Extraction The dried powder material was subjected to defat by using Petroleum ether to remove waxy substances and chlorophyll . The marc, which was defatted with petroleum ether was dried and extracted with using ethanol in a soxhlet extractor for 72 hours. The solvent was then subjected to distillation and the resulting semisolid mass was dried and then stored in a desiccator to get a yield. INFERENCES : From the above phytochemical screening the EETC shows the presence of Alkaloids,carbohydrates,saponions, glycosides and phytosterols. EECS shows the presence of proteins and aminoacids, alkaloids, saponins, glycosides and phytosterols. EECRS shows the presence of proteins and aminoacids, saponins ,glycosides and phytosterols. These above said constituents present all the three extracts may be responsible for the pharmacological activities. For hepatoprotective activity animals are divided in to nine groups after seven days treatment with EETC ,EECS ,EECRS, ISO-I and ISO-2 restored the level of serum biochemical parameters(viz SGOT,SGPT,Total biluribin,ALP,Direct biluribin and Total Protein) towards normalization. But the effect of PHF on these parameters was comparable to that of standard Silymarin. Histopathological report also supported that liver section were in normal circumstance. In antiulcer activity EETC ,EECS ,EECRS, ISO-I and ISO-2, shows a marked effect in gastro protective activity. But HF shows significant effect in reducing ulcer when compared with standard drug Ranitidine. CONCLUSION Plants from Cucurbitaceae family was selected for the investigation because most of research work carried out in this family was focused on seeds and fruits. Hence Trichosanthes cucumerina L. and Cucumis sativus L. selected from this family and carried out preliminary phytochemical investigation and pharmacological screening like hepatoprotective , antiulcer ,diuretic and antioxidant activity. All the plant extracts shows considerable result in all the above mentioned screening hence it was planned to prepare herbal formulation and isolation of active substance from the plant extract. As per the serum parameters result the formulation has the significant effect to normalize the serum parameters when compared to standard drug Sylimarin. There is also significant results given by formulation in gastro protective effect . Diuretic and antioxidant activity also shows the same report. Over all it was concluded that the plant extracts of EETC,EECS and EECRS is safe at up to the dose level of 2000mg/kg. It can be used as a natural source of Hepatoprotectant, antiulcer drug,diuretic drug and antioxidants which can be used in the prevention of diseases caused by free radicals. The combination of all these three plant extracts(EETC,EECS and EECRS) showed potent hepatoprotective and diuretic drug. The formulation of other two plant extracts showed potent antiulcer and antioxidant drug. It also need to study to isolate and characterize the some more active compounds that are responsible for the all the above activities
