Vol. 76, No. 2: 103-108, 2007 ACTA SOCIETATIS BOTANICORUM POLONIAE 103 ANTHRACENE DERIVATIVES IN SOME SPECIES OF RUMEX L. GENUS MAGDALENA WEGIERA1, HELENA D. SMOLARZ1, DOROTA WIANOWSKA2, ANDRZEJ L. DAWIDOWICZ2 1 Departament of Pharmaceutical Botany Skubiszewski Medical University of Lublin Chodki 1, 20-039 Lublin, Poland e-mail: [email protected] 2 Faculty of Chemistry, Marii Curie-Sk³odowska University of Lublin (Received: June 1, 2006. Accepted: September 5, 2006) ABSTRACT Eight anthracene derivatives (chrysophanol, physcion, emodin, aloe-emodin, rhein, barbaloin, sennoside A and sennoside B) were signified in six species of Rumex L genus: R. acetosa L., R. acetosella L., R. confertus Willd., R. crispus L., R. hydrolapathum Huds. and R. obtusifolius L. For the investigations methanolic extracts were pre- pared from the roots, leaves and fruits of these species. Reverse Phase High Performance Liquid Chromatography was applied for separation, identification and quantitative determination of anthracene derivatives. The identity of these compounds was further confirmed with UV-VIS. Received data were compared. The roots are the best organs for the accumulation of anthraquinones. The total amount of the detected compo- unds was the largest in the roots of R. confertus (163.42 mg/g), smaller in roots R. crispus (25.22 mg/g) and the smallest in roots of R. hydrolapathum (1.02 mg/g).

Naturforsch. 49c, 404-406 (1994); received January 31, 1994 Rumex crispus, Polygonaceae. Anthraquinone, Glycoside The anthraquinone glycoside contents of various parts of Rumex crispus L. (Polygonaceae) in different vegetation stages were investigated by thin layer chromatographic and spectro- photometric methods. The data showed that the percentage of anthraquinone glycoside in all parts of plant increased at each stage. Anthraquinone glycoside content was increased in leaf, stem, fruit and root from 0.05 to 0.40%. from 0.03 to 0.46%. from 0.08 to 0.34%, and from 0.35 to 0.91% respectively. From the roots of R. crispus, emodin- 8 -glucoside, RGA (isolated in our laboratory, its structure was not elucidated), traceable amount of glucofran- gulin B and an unknown glycoside ( R f = 0.28 in ethyl acetate:methanol:water/100:20:10) was detected in which the concentration was increased from May to August. The other parts of plant contained only emodin- 8 -glucoside. Introduction In the present investigation various parts of Rumex L. (Polygonaceae) is one of several Rumex crispus, leaf, stem, fruit and root were ana genera which is characterized by the presence lyzed separately for their anthraquinone glycoside of anthraquinone derivatives.

Regulation of Urtica Dioica L. on Grasslands Vozár Ľ., Jančovič J
Regulation of Urtica dioica L. on grasslands Vozár Ľ., Jančovič J. and Bačová S. Slovak Agricultural University in Nitra, Faculty of Agrobiology and Food Resources, Department of Grassland Ecosystems and Forage Crops, Nitra, Slovakia E-mail: [email protected] Abstract We studied some possibilities for the biological and mechanical control of the ground cover of Galio-Urticetea Passarge ex Kopecký 1969, with the association of Urtica dioica L., in a place which belongs to the village of Chvojnica in the Strážov Hills in the middle of Slovakia. The place was used as a corral for cattle in the past. Cattle had a great influence on the eutrophication of the soil. The floristic composition changed there. We examined 4 variants in our experiment: 1st – control, without cutting; 2nd – cutting every 5th week with biomass being taken away; 3rd – cutting every 5th week with mulch- ing; 4th –Dactylis glomerata L. and Trifolium repens L. reseeding, cutting four times a year. According to the five-year results of the different types of regulation it seems that the best way of regulation is reseeding with the strong competitive species Dactylis glomerata L. and Trifolium repens L. Keywords: regulation of weed infestation, Urtica dioica L., stand eutrophication, corral for cattle Introduction Livestock numbers have decreased to 1/3 of their original level in Slovakia since the year 1989 (Green Report, 2007). The area of grassland utilisation has been reduced. Inaccessible areas have been abandoned and degraded and have become covered by weeds. These stands have low or toxic forage value and these weeds also have negative influences on the en- vironment and formation of the countryside. -

Rumex Crispus L.; Curly Dock R
A WEED REPORT from the book Weed Control in Natural Areas in the Western United States This WEED REPORT does not constitute a formal recommendation. When using herbicides always read the label, and when in doubt consult your farm advisor or county agent. This WEED REPORT is an excerpt from the book Weed Control in Natural Areas in the Western United States and is available wholesale through the UC Weed Research & Information Center (wric.ucdavis.edu) or retail through the Western Society of Weed Science (wsweedscience.org) or the California Invasive Species Council (cal-ipc.org). Rumex crispus L.; curly dock R. crispus R. obtusifolius Rumex obtusifolius L.; broadleaf dock Curly and broadleaf dock Family: Polygonaceae Range: Curly dock is found throughout the U.S., including every western state. Broadleaf dock is found in most of the western states, except Nevada, Wyoming and North Dakota. Habitat: Ditches, roadsides, wetlands, meadows, riparian areas, alfalfa and pasture fields (especially with poor drainage), orchards and other disturbed moist areas. Plants prefer wet to moist soils but tolerate periods of dryness, and can grow in most climates and soil types. Origin: R. crispus, Eurasia; R. obtusifolia, western Europe. Impact: Both species can be very competitive and outcompete more desirable vegetation for water, nutrients and light. Under certain conditions, they can accumulate soluble oxalates making them toxic to livestock. California Invasive Plant Council (Cal-IPC) Inventory: R. crispus, Limited Invasiveness Both species are erect perennials from 1.5 to 3 ft tall, occasionally to 5 ft tall. Curly dock leaves are lanceolate and up to 20 inches long, whereas broadleaf dock has lanceolate-ovate leaves that are up to 30 inches long. -

Foraged leafy greens are consumed around the globe, including in urban areas, and may play a larger role when food is scarce or expensive. It is thus important to assess the safety and nutritional value of wild greens foraged in urban environments. Methods. Field observations, soil tests, and nutritional and toxicology tests on plant tissue were conducted for three sites, each roughly 9 square blocks, in disadvantaged neighborhoods in the East San Francisco Bay Area in 2014–2015. The sites included mixed-use areas and areas with high vehicle traffic. Results. Edible wild greens were abundant, even during record droughts. Soil at some survey sites had elevated concentrations of lead and cadmium, but tissue tests suggest that rinsed greens are safe to eat. -

Urtica Urens
Dwarf Nettle Urtica urens Weed management guide for Australian vegetable production INTEGRATED WEED MANAGEMENT Identification Dwarf nettle (Urtica urens) is an annual herbaceous plant, native to Mediterranean Europe, that grows between 10 and 75 cm in height. Leaves are up to 6 cm in length but often 1-3 cm, oval to elliptical in shape, deeply toothed or serrated on the edges, green to dark green, and covered with scattered stinging hairs. Clusters of small, greenish-white flowers form where 1 the leaves join the stems. Dwarf nettle is also known in Australia as small nettle, lesser nettle, or stinging nettle. Vegetable farmers are likely to be very familiar with it where it is found on their farm, and to be well aware of how to identify it. However depending on its stage of growth, it may be possible to mis-identify it as tall nettle (Urtica dioica), native scrub 2 nettle (Urtica incisa) or potentially deadnettle (Lamium amplexicaule), particularly where the plants are recently germinated. Figure 1 includes a series of photos of dwarf nettle at different life stages in order to facilitate correct identifica- tion on-farm, from a young seedling through to a mature 3 flowering plant. Dwarf nettle may be mis-identified as native scrub nettle (Urtica incisa), a common species native to Australia. 4 Compared to dwarf nettle, native scrub nettle reaches up to 1m in height, has longer lance-shaped leaves (up to 12 cm) that are paler beneath, fewer stinging hairs, and spike-like clusters of flowers that can be longer than the leaf stalks.
