INTRODUCTION India has a flora that is widely distributed throughout the country which is one of the richest with enormous medicinal and aromatic plants. It constitutes 11% of total known flora having medical property (Sati et al., 2010). Herbal drugs have been the basis of treatment and cure for innumerable diseases and functional condition in traditional systems practiced as Ayurveda, Unani and Siddha. Currently, multiple drug resistance microorganisms have been developed due to indiscriminate use of commercial antimicrobial drugs generally used in the treatment of infectious disease (Bhaskarwar et al., 2008) thus additional therapy is needed for the future. At present, there has been a lot of attention focused on producing medicines and products that are natural. Plants are good sources for new, safe, eco friendly and renewable drugs. Plants are used medically in several countries and are a basis for many effective and prevailing drugs (Srivastava et al., 2008). A number of plants with substantial antimicrobial activity have been stated in different traditional works (Jones et al., 1996 and Satish et al., 1999). Numerous medicinal plants are used daily in Ayurvedic practices. In India more than 7000 medicinal plants are recognized. According to a report of World Health Organization, more than 80% of world’s populations depend on traditional medication for the primary healthcare requirements (Umamaheswari et al., 2008). The fewer availability and high rate of new generation antibiotics needs substitute medicines with antimicrobial activity (Poovendran et al., 2011). Therapeutic plants represent a ridiculous source of antimicrobial mediators. Green plants represent a reservoir of effective chemotherapeutic agent and can provide valuable sources of natural pesticides. Bio pesticides have been suggested as an effective 1 substitute for chemicals. Majority of medicinal plant species are rich in bio-molecule contents which can cope up with health hazard. Recently, antibacterial activities of many plants species have been reported by Pandey and Mishra (2010). The vast majority of modern medications were derived originally from ancient herbal traditions. There are numerous natural products of plants which shows an antifungal, antibacterial and antiprotozoal activities that could be used either systemically or locally (Cowman, M.M. 1999). Many of the medicinal plants used in traditional medicine are readily available in rural areas which are relatively cheaper than modern medicine. Nowadays many of the medicines are acquired from natural products or partial synthetic byproducts of natural sources and used in the customary systems of medicine (Sukanya et al., 2009). Most of these published works come from many countries that are still in practice and the herbal medicines are used for treatment of various diseases for practical and economic reasons (Nascimento et al., 2000). Many plants are used by native groups to satisfy their food needs, nutrition and health and found a source of extra income and employment (Sandhya et al., 2006; FAO, 2012 and Visweswari et al., 2013). Usually, the plants consist of metabolites that deliberates to them, have more medicinal advantages that are at the basis of their consumption by people (Zwenger and Basu, 2008; Visweswari et al., 2013 and Adjatin et al., 2013). The various parts of the plants are conventionally used for the treatment of several complaints and as an antidote for snake bites and scorpion stings (Uma Devi, 2001). The secondary metabolites are the bioactive substances in plants. Most promising targets in search for such biologically active compounds are plants used 2 in folk medicines. Medicinal plants, with their wide variety of chemical constituents, offer a promising source of new antimicrobial principle (Cooper, 2004 and Patwardhan et al., 2005). Several leaves extract have been found to have antimicrobial activity against various microorganisms (Kim et al., 2004).

Received 29 March, 2019; Accepted 11 July, 2019 Cleome gynandra L. is one of the traditional leafy vegetables in Africa and Asia providing essential minerals and vitamins to the diet and income of resource poor communities. Despite these benefits, the crop has not been studied extensively resulting in lack of scientific information to guide crop improvement research and associated agronomic practices. The taxonomy of the crop, its reproductive behaviour, genome size, ploidy level and origin are neither readily available nor well understood. This paper reviews existing literatures in these areas to provide information for future research and development of the crop. Reading the review, one could appreciate the taxonomic classification of the genus is still under debate despite recent molecular studies that placed the crop in the Cleomaceae family as opposed to previous studies that classified it under Capparaceae family. According to present review the crop belongs to the Kingdom of Plantae, Phylum spermatophyta, Division Magnoliophyta, Class Magnoliopsida, Order Brassicales and the Family of Cleomaceae.

  • Cleome Viscosa Linn: a Natural Source of Pharmaceuticals and Pesticides R Ticle Ravi Kant Upadhyay Department of Zoology, D
    [Downloaded free from http://www.greenpharmacy.info on Friday, July 24, 2015, IP: 223.30.225.254] Cleome viscosa Linn: A natural source of pharmaceuticals and pesticides TICLE R Ravi Kant Upadhyay Department of Zoology, D. D. U. Gorakhpur University, Gorakhpur, Uttar Pradesh, India A Cleome viscosa is an indigenous medicinal plant that shows large seasonal biodiversity in North-Western states of India. It is a common weed mainly found in crop fields, in waste lands, wet and grassy places all over the plains of India. Plant bears yellow flowers and long slender pods containing seeds that resemble those of mustard with strong penetrating odor in rainy and post rainy season. Seeds are oil producing and are used for making cattle cake. C. viscosa leaves and young shoots are used to cook like a vegetable, which is having EVIEW sharp mustard-like flavor. Fatty oils of the seeds of C. viscosa contain major fatty acids, as methyl esters, of the oils mainly palmitic R acid (10.2–13.4%), stearic acid (7.2–10.2%), oleic acid (16.9–27.1%) and linoleic acid (47.0–61.1%). Oil is rich in unsaturated fatty acids and nutrients, especially Vitamins A and C, minerals, calcium, iron and protein. Plant also contains free gallic acid, gallotannins, iridoid, saponins and terpinoid polyphenolic compounds, which are well-known antioxidizing agents. Its oil is very similar in fatty acid composition to the nonedible oils of rubber, jatropha, soybean, safflower, linseed and rapeseed edible oils. Due to the presence of oils, plant can be used as a good source of green biodiesel.

  • Cotton Production, Physiology and Economics
    Cotton Production, Physiology and Economics 53 Cotton Genotypes Performance under Rainfed and Irrigated Conditions in two Regions of Northern Argentina Marcelo Paytas1 and Jose Tarrago2 1INTA EEA Reconquista, Santa Fe, (3560), Argentina 2INTA EEA Las Brenas, Chaco, (3722), Argentina E-mail: [email protected] Abstract—Narrow-row cotton production systems have became popular in Argentina in the last few years. It is mainly cultivated under rainfed conditions as a low input crop which is challenging and risky. Irrigation can improve the performance of current genotypes and may reduce the variability in yield produced under rainfed conditions across different environments. This research was aimed to understand the differences in growth, development and yield of two cotton cultivars in a narrow row system under rainfed and irrigated conditions. Experiments were conducted during 2010-11 under rainfed and irrigated conditions at the Research Station of INTA Reconquista, Santa Fe (29º11´S, 59º42’W) and INTA Las Brenas, Chaco (27º05´S, 61º06’W). The annual rainfall and its distribution, temperatures, evaporative demand and soil types differ between both cotton regions. The experimental design in each location was a split plot design with four replications: two genotypes (NuOpal and DP402) with two moisture levels (rainfed and irrigated). The results indicated differences between genotypes in terms of days to crop maturity. Earliness was found for DP402 for both locations compared with NuOpal. However, no significant differences in terms of phenology were found between rainfed and irrigated conditions due the amount of soil water content available from rainfall for the plant in both systems. Dry matter production and partitioning to reproductive organs was affected by genotypes and moisture levels.
