The aim of this research was to investigate possible phenotypic variation profile of Marsilea crenata Presl. cultivated in water and in the soil, to find alternative cultivation techniques to fulfill the increasing demand for pollutant-free plants. Phenotypic profile was investigated through macroscopic and microscopic examinations of all plant parts, and phytochemical screening on the ethanol extract of the leaves using thin layer chromatography technique was conducted to detect the terpenoid constituents. Results showed a variation of phenotypic profiles in the macroscopic examination caused by different cultivation methods. Phytochemical screening showed spots of terpenoid compounds with different color intensity. No differences were found in the microscopic examination of the leaves, petioles, and stems. Since major profile changes did not occur, M. crenata is recommended to be cultivated in water as its original habitat by providing a better caring and quality of water. Due to its phytoremediation property, it is necessary to grow M. crenata in pollutant-free water.

Free radicals and reactive species are widely believed to contribute to the development of several diseases by causing oxidative stress and eventually oxidative. Vernonia amygdalina (Astereacea) is a small shrub or tree between 1 and 5m high growing throughout tropical Africa. Plants are generally known as bitter leaves is well cultivated and is a general market for merchandise in several countries. The purpose of this study was to determine the antioxidant activity of hexane fraction from ethanol extract od Frican leaves (Vernonia amygdalina Del.). The method used in this study was the DPPH (1,1-Diphenil-2-Picrylhydrazyl) method. The result of phytochemical screening showed that ethanolic extract of African leaves contained a composition of secondary metabolites of alkaloids, flavonoids, tannins, steroids/triterpenoids and saponins. The antioxidant activity of the extract of n-hexane fraction was classified as very weak with an IC50 value of 317.98 ppm.

Fenugreek Leaves

Developing countries, where malaria is one of the most prevalent diseases, still rely on traditional medicine as a source for the treatment of this disease. For the present study,Trigonella foenum-graecumL. (fenugreek) were collected from Coimbatore, Tamilnadu, India. The test plant has been used in India by traditional healers for the treatment of fever as well as other diseases. The active principle was extracted out in different solvent systems to assess the anti-plasmodial potential, with an aim that they can further be utilized to formulate drugs.In vitroanti-plasmodial assay of the extracted fractions of fenugreek leaves was carried out using laboratory adapted chloroquine sensitive and resistantPlasmodium falciparumisolates. Schizont maturation inhibition assay was adopted to analyze the potential of the extracts. Ethanol extract (50%) seemed to possess profound anti-plasmodial activity with IC50value of 8.75 ± 0.35 µg ml−1and 10.25 ± 0.35 µg ml−1against chloroquine sensitive and resistantP. falciparumisolates, respectively. Among the investigated six fractions of the plant extracts, two were found to have significant anti-plasmodial activity with IC50values <10 µg ml−1, namely ethanol and butanol extracts. Two extracts chloroform and ethyl acetate showed moderate activity with IC50values ranging from 10 to 20 µg ml−1, and the other two extracts, hexane and water appeared to be inactive with IC50values >85 µg ml−1. In addition, preliminary phytochemical screening of the various extracts indicated the presence of alkaloids, saponin, tannin like phenolic compounds, flavonoids and steroids.

Aim of the study was to analyze the phytochemical constituents and estimation of total flavonoids and phenolic compounds of leaves and roots of the medicinal plant Lagascea mollis. Methanol extract of dried leaves and roots of L. mollis was prepared by using soxhlet apparatus. The extract prepared was tested forpreliminary qualitative phytochemical screening, followed by the quantitative estimation of total flavonoids and phenols by spectroscopy. The selected plant parts were found to contain alkaloids, flavonoids and terpenoids in both parts and saponin is present only in leaf. In quantitative estimation the reports revealedthe presence 0.017 and 0.013 mgRE/g extract and 458.91 and 704.50 mgGAE/g extract total flavonoids and phenolic compounds in leaf and root extract respectively. These major phytoconstituents present in this species may be accounted as factors for the medicinal importance of L. mollis.

Different parts of Vitellaria paradoxa plant have many applications in ethno-medicine. Some of the uses of this plant include treatment of diarrhoea and other GIT disorders. In this study the antidiarrhoeal activity of the ethanol extract of Vitellaria paradoxa was evaluated using three experimental models: Castor oil-induced diarrhoea; small intestinal motility and intestinal fluid accumulation (enteropooling) models in mice. Five groups of five mice were used for each model. Group one mice received 10 ml/kg of distilled water, while groups 2, 3, and 4 received 125, 250 and 500 mg/kg of the extract orally respectively. Group 5 mice received Loperamide 5 mg/kg orally. Oral median lethal dose (LD50) of the extract was determined using OECD (2008) Guideline 425. Phytochemical studies were conducted using standard procedures. The LD50 was estimated to be greater than 5000 mg/kg body weight and there were no signs of mortality or visible signs of toxicity in all the mice treated. Phytochemical screening revealed the presence of carbohydrates, alkaloids, flavonoids, saponins, tannins, triterpenes, steroids, cardiac glycosides and anthraquinones glycosides. Extract showed a dose-dependent anti-diarrhoeal activity by reducing stool frequency and consistency. The extract at the higher doses significantly (p < 0.05) inhibited GIT motility and castor oil-induced enteropooling, comparable to that of the reference control drug Loperamide. The study showed that ethanol stem bark extract of Vitellaria paradoxa possess anti-diarrhoeal activity and thus justifies its ethno-medicinal use in the treatment of diarrhoea.

Antibacterial Potential

The large variety of plant specimens found in Brazil with still unexplored medicinal potential, combined with the increase in bacterial resistance to antimicrobials traditionally employed, opens an important field of research aimed at prospecting new drugs. In this context the objective of this work was to evaluate the antibacterial potential of Eugenia dysenterica and to characterize its phytochemical profile. Ethanolic extracts were obtained by drying, grinding, turbo-extraction and lyophilization of the leaves of the plant. The CIM and CBM tests were performed to evaluate the antimicrobial potential on the following strains: Proteus mirabilis ATCC 15290, Echerichia coli ATCC25922, Staphylococcus aureus ATCC29213 and Staphylococcus epidermides ATCC 12228. E. dysenterica presented bactericidal action at 2mg.ml-1 against S. aureus and bacteriostatic at 1mg.ml-1 against P. mirabilis. Several phenolic compounds were detected in the phytochemical screening, and the presence of these compounds may justify the biological potential of this plant.
