Research Institute of Chemistry, International Center for Chemical and Biological Sciences, University of Karachi, Karachi-75270, Pakistan. (Received September 11, 2011; Revised May 9, 2012 Accepted June 15, 2012) Abstract: The study of the chemical constituents of the whole plant of Erigeron bonariensis (L.) has resulted in the isolation and characterization of a new and nine known compounds. The known compounds were identified as stigmasterol (1), freideline ( 2), 1,3-dihydroxy-3R,5 R-dicaffeoyloxy cyclohexane carboxylic acid methyl ester ( 3), 1R,3 R-dihydroxy- 4S,5 R-dicaffeoyloxycyclohexane carboxylic acid methyl ester ( 4), quercitrin ( 5), caffeic acid ( 6), 3-(3,4- dihydroxyphenyl)acrylic acid 1-(3,4-dihydroxyphenyl)-2-methoxycarbonylethyl ester (8), benzyl O-β-D-glucopyranoside (9), and 2-phenylethyl-β-D-glucopyranoside ( 10 ). The aromatic glycoside, erigoside G ( 7) is reported as new natural compound. The above compounds were individually identified by spectroscopic analyses and comparisons with reported data. The chemotaxonomic studies of isolated compounds have been discussed. Keywords: Erigeron bonariensis ; natural products; chemotaxonomic studies. 1.Plant Source Erigeron bonariensis (L.) is locally called “gulava” or “mrich booti” and is traditionally used in urine problems.

  • Protecting Urban Water Quality: New Surface Water Regulations of 2012
    Protecting Urban Water Quality: New Surface Water Regulations of 2012 Michael P Ensminger, Staff Environmental Scientist, California Department of Pesticide Regulation, 1001 I Street, Sacramento, CA 95812, [email protected] The California Department of Pesticide Regulation adopted new surface water regulations on June 19, 2012. The regulations restrict outdoor urban applications of pyrethroid insecticides made by professional applicators. Pyrethroids are highly active insecticides that control crawling, chewing, and flying insects as cockroaches, ants, beetles, caterpillars, termites, mosquitos, and wasps; in addition they are highly active on arachnids as spiders, ticks, and mites. Pyrethroids are highly hydrophobic and sorb to soils and sediment; half-lives of pyrethroids range from weeks to more than a year. Pyrethroids are being regulated in urban (non-agricultural) areas because of the following characteristics: 1) high use in urban areas; 2) prone to runoff in urban areas due to the engineering design of urban areas, especially during rainstorms; 3) more frequently detected in urban areas than in agricultural areas; 4) highly toxic to aquatic invertebrates and fish; 5) cause aquatic invertebrate toxicity when detected in surface waters. The new surface water regulations will reduce the amount of pyrethroids applied by limiting applications to spot applications, crack and crevice applications, pin stream applications, and by limiting applications to impervious surfaces. Because more pyrethroids runoff during rainstorm events, applications are prohibited during rainfall (except under eaves), in standing water, to stormdrains and curbside gutters, and unprotected termiticide applications. More specific information can be found at the CDPR website (http://cdpr.ca.gov/docs/legbills/calcode/040501.htm).

  • Ridha El Mokni & Duilio Iamonico a New Record for the Non-Native Flora
    Fl. Medit. 28: 145-153 doi: 10.7320/FlMedit28.145 Version of Record published online on 24 September 2018 Ridha El Mokni & Duilio Iamonico A new record for the non-native flora of Tunisia, Eclipta prostrata (Asteraceae), and a note on the national status of Erigeron bonariensis, Symphyotrichum squamatum (Asteraceae), and Lepidium didymum (Brassicaceae) Abstract El Mokni, R. & Iamonico, D.: A new record for the non-native flora of Tunisia, Eclipta pros- trata (Asteraceae), and a note on the national status of Erigeron bonariensis, Symphyotrichum squamatum (Asteraceae), and Lepidium didymum (Brassicaceae). — Fl. Medit. 28: 145-153. 2018. — ISSN: 1120-4052 printed, 2240-4538 online. Floristic and phytosociological surveys in NE-Tunisia allowed to discover Eclipta prostrata (Asteraceae) which represents the first record at national level. A description of the species, notes on its ecology and phytosociological remarks are provided. We also stated, for the first time in Tunisia, the status of naturalization of three species (Erigeron bonariensis, Symphyotrichum squamatum, and Lepidium didymum) which does not appear still published until now. Key words: Alien species, Naturalization, North Africa. Introduction Invasions by non-indigenous plant species has become an important component of glob- al environmental change (e.g., Mack & al. 2000). Ruderal environments as well as coastal and riverine habitats have often been reported to harbor many neophytes (Sobrino & al. 2002; Bruno & al. 2004; Dark 2004; Von Holle & Motzkin 2007; Chytrý & al. 2007). Several studies of the coastal region of the Mediterranean Basin have shown a high degree of naturalization of introduced species (see e.g., Badano & Pugnaire 2004; Campos & al. 2004).

  • 24Th Annual Western Aquatic Plant Management Society Meeting March 10-11, 2005 Denver, CO
    24th Annual Western Aquatic Plant Management Society Meeting March 10-11, 2005 Denver, CO ABSTRACTS Oral Presentations (Alphabetized by first author’s last name) Preliminary evaluation of SolarBee effects on water quality at Lake Tahoe. Lars Anderson, Wailun Tan, and Chris Mallek; USDA-ARS Exotic and Invasive Weed Research, UCDavis One Shields Ave Davis, CA 95616 E-mail: [email protected] The SolarBee Corporation installed four water circulation systems at Tahoe Keys in the early summer of 2004. Subsequently, this study was begun to assess impacts of the systems on water quality, sediments, plant quality (CHN) and ability of adjacent sediments to support growth of Eurasian watermilfoil (Myriophyllum spicatum). During July, 2004, transects were established at three of the SolarBee stations and at three “control” stations in the West Tahoe Keys marina (West Basin) areas where no SolarBee systems were installed. Sampling stations were established at 4, 12, 36 and 100 meters from the SolarBee systems. During each sampling period (July, August, September (twice), November), light levels (at 20 cm-intervals) and water quality measurements (temp, DO, turbidity, pH) were recorded mid-depth and 20cm from the bottom. Triplicate samples of sediments were taken along the transects using an Ekman dredge (15cm x 15cm x15cm) and combined to form one sediment sample at each station (point) along each transect. Sediments were distributed into triplicate 1.5 l containers and each container was planted with three 15 cm apical shoots of M. spicatum obtained from the Tahoe Keys Marina. Planted containers were placed in a randomized pattern in temperature-controlled fiberglass tanks, 1 m deep, with recirculating deionized water and exposed to ca.
