ABSTRACT Bioactive compounds, phytochemicals, have long been analyzed in order to clarify their pharmacological and therapeutic importance. Phenolic and polyphenolic compounds that are founded in plants have a good reputation as they are fulfilling a crucial function to avert and treatment of disparate diseases. Phytochemical analysis and pharmacological studies research therapeutic potential and mechanism of folk medicinal plants about their anti-oxidant, anti-cancer, anti-inflammatory and anti-bacterial activity. Epilobium hirsutum L., having a rich flavonoids content, has been used traditionally for prevention and treatment of some diseases throughout the human history. The present review highlights the chemical components, pharmacological and therapeutic effects of Epilobium hirsutum L. and may help researchers in further extensive research and development of new therapeutics based on Epilobium hirsutum L.

  • Plant Species to AVOID for Landscaping, Revegetation, and Restoration Colorado Native Plant Society Revised by the Horticulture and Restoration Committee, May, 2002
    Plant Species to AVOID for Landscaping, Revegetation, and Restoration Colorado Native Plant Society Revised by the Horticulture and Restoration Committee, May, 2002 The plants listed below are invasive exotic species which threaten or potentially threaten natural areas, agricultural lands, and gardens. This is a working list of species which have escaped from landscaping, reclamation projects, and agricultural activity. All problem plants may not be included; contact the Colorado Dept. of Agriculture for more information (see references below). Some drought resistent, well adapted exotic plants suggested for landscaping survive successfully outside cultivation. If you are unsure about introducing a new plant into your garden or reclamation/restoration plans, maintain a conservative approach. Try to research a new plant thoroughly before using it, or omit it from your plans. While there are thousands of introduced plants which pose no threats, there are some that become invasive, displacing and outcompeting native vegetation, and cost land managers time and money to deal with. If you introduce a plant and notice it becoming aggressive and invasive, remove it and report your experience to us, your county extension agent, and the grower. If you see a plant for sale that is listed on the Colorado Noxious Weed List, please report it to the CO Dept. of Ag. (Jerry Cochran, Nursery Specialist; 303.239.4153). This list will be updated periodically as new information is received.

No part of this publication may be reproduced, stored in a retrieval system or database, or transmitted in any form or by any means, including photocopying, without written permission of the authors. Produced with financial assistance from The Couchiching Conservancy. The City of Kawartha Lakes Flora Project is sponsored by the Kawartha Field Naturalists based in Fenelon Falls, Ontario. In 2008, information about plants in CKL was scattered and scarce. At the urging of Michael Oldham, Biologist at the Natural Heritage Information Centre at the Ontario Ministry of Natural Resources and Forestry, Dale Leadbeater and Anne Barbour formed a committee with goals to: • Generate a list of species found in CKL and their distribution, vouchered by specimens to be housed at the Royal Ontario Museum in Toronto, making them available for future study by the scientific community; • Improve understanding of natural heritage systems in the CKL; • Provide insight into changes in the local plant communities as a result of pressures from introduced species, climate change and population growth; and, • Publish the findings of the project . Over eight years, more than 200 volunteers and landowners collected almost 2000 voucher specimens, with the permission of landowners. Over 10,000 observations and literature records have been databased. The project has documented 150 new species of which 60 are introduced, 90 are native and one species that had never been reported in Ontario to date.

Experimental studies have demonstrated that Epilobium extracts possess a broad range of pharmacological and therapeutic effects, including antioxidant, anti-proliferative, anti-inflammatory, an- tibacterial, and anti-aging properties. Flavonoids and ellagitannins, such as oenothein B, are among the com- pounds considered to be the primary biologically active components in Epilobium extracts.

Although this grass is widely distributed in central and south-eastern Europe reaching dominance in certain grassland types, the knowledge on its ecology and coenology is very poor. More- over, some of the published data on its distribution are wrongly related to Avenula praeusta. We studied the taxon within an area of about 300 km2 (Central Slovakia) where it occurs in diverse habitats. Data from a systematic phytosociological survey were used to assess interspecific associations and ecologi- cal indicator values of the taxon. Detailed measurements from a transect along a spruce colonisation gradient were used to evaluate its relationship to a set of topographical, microclimatical, pedological and soil-microbiological characteristics. Tillers of A. adsurgens subsp. adsurgens were cultivated for two growing seasons to estimate characteristics of its clonal morphology and growth and its ability of spatial spreading. In the studied area, the taxon occurred mainly over the volcanic bedrock along a wide range of altitudes.
