(Received 26th March 2007 – Accepted 11th June 2007) ABSTRACT Surface compounds were obtained by a methylene chloride extraction of fresh flower heads of Flourensia thurifera. The methylene chloride extract was purified by column chromatography and analyzed by GC-MS, leading to the identification of several monoterpenes, sesquiterpenes and diterpenes. A hydrocarbon fraction of n-alkanes from C23 to C31 and C33 was also identified. Headspace analysis of the fresh flower heads was also carried out. Different proportions of the same mono- and some of the sesquiterpenes were identified in the volatile fraction. The presence of mono- and sesquiterpenes in the flower heads is in agreement with the fact that these families of compounds have been identified in other Flourensia species. keywords: Flourensia thurifera.; Asteraceae; Flower heads; Methylene chloride extract; Headspace; GC-MS; Monoterpenes; Sesquiterpenes; Diterpenes; Hydrocarbons INTRODUCTION and nitrogen with no detectable organic impurities, was attached through a regulator which controlled the air flow.

    27 Flourensia cernua DC: A Plant from Mexican Semiarid Regions with a Broad Spectrum of Action for Disease Control Diana Jasso de Rodríguez1, F. Daniel Hernández-Castillo1, Susana Solís-Gaona1, Raúl Rodríguez- García1 and Rosa M. Rodríguez-Jasso2 1Universidad Autónoma Agraria Antonio Narro (UAAAN), Buenavista, Saltillo, Coahuila 2Centre of Biological Engineering, University of Minho,Campus Gualtar 1México 2Portugal 1. Introduction Mexico has an extensive variety of plants, it is the world´s fourth richest country in this aspect. Some 25,000 species are registered, and it is thought that there are approximately 30, 000 not described. Particularly the regions of the north of Mexico, with their semiarid climate, have a great number and variety of wild plants grown under extreme climatic conditions. Wild species which have compounds with flavonoid structures, sesquiterpenoids, acetylenes, p-acetophenones, benzofurans, and benzopyrans grow in these regions. The polyphenolic compounds include tannins and flavonoids which have therapeutic uses due to their anti-inflammatory, antifungal, antibacterial, antioxidant, and healing properties. Flourensia cernua is an endemic species which grows in semiarid zones of Mexico and contains polyphenolic, lactone, benzofuran, and benzopyran compounds which give it a potential use for disease control. In this work, F. cernua is reviewed in terms of its geographical distribution in Mexico, traditional uses, bioactive compounds identified for controlling fungi, bacteria, and insects, as well as cytotoxic activity. 2. Common names It is commonly known in different ways, as it is found in the United States of America as well as in Mexico. The names given in the United States of America are: tarbush, hojase, American-tarbush, black-brush, varnish-brush, and hojasen (Correl and Johnston, 1970; Vines, 1960).

In this chapter, we attempt to describe the major types of vegetation cover in this vast region as they occurred in pre- Columbian times and outline the conditions that support them. Examining the large-scale phytogeographic regions characterized by each major cover type (see Fig. I), we provide basic information on geology, geological history, topography, and climate; describe variants of physiognomy (vegetation structure) and geography; discuss transitions; and examine some floristic patterns and affinities within and among these regions.

  • Floribunda Bahiensis AH307 Chapada Diamantina, Brazil
    VOLUME 15 NUMBER 50 Floribunda bahiensis AH307 Chapada Diamantina, Brazil Photo - a -hofacker Uebelmannia flavispina Uebelmannia pectinifera PROBLEM UEBELMANNIAS From D.Angus Some years ago I bought one or two imported Uebelmannias which I tried to get established on their own roots. Although one of these plants was still with me after a year, the only way to describe my attempt to grow these plants is to say that it was a failure. Despite being careful with the watering and giving extra heat, they were all lost. Since then I have kept clear of Uebelmannias, until a couple of years ago when I obtained one or two grafted seedlings from a local grower. As soon as these plants got to a decent size they began to send down roots from the bottom of the graft. From my previous experience I did not want to take these plants off their graft and try to get them away on their own roots. So I reduced the length of the stock on U.flavispina to about one inch, and then got it rerooted. After that I cut down the length of stock on U.pectinifera and on U.pectinifera v.multicostata to a bare half an inch and they are now obviously re-rooted. I do not intend upsetting them by trying to find out if there is any of the original grafting stock left, or whether it has just dried away leaving the plant on its own roots. Even some of the offsets on these grafted Uebelmannias put down roots, so I have now removed two or three of these offsets and put them on a gritty compost on a heated bed, to see how they get on.

  • Revision of the Genus Flourensia
    :' ~'~., ,0., • ',"'. " REVISION OF THE GENUS FLOURENSIA. By S. F. BLAKE. INTRODUCTION. , The genus Flouremia, established by De Candolle 1 in 1836 to , include a Chilean plant described by Molina as a Heliamhus and three new species, was divided by him into two groups one, Chilean, including the two radiate species F. thurifera (Mol.) DC., with a variety angustifolia DC., and F. corymbosa (a true Viguiera); the other, Mexican, with the two discoid species F. laurifolia and F. cemua, both based on Berlandier's collections. In the Genera Plan­ tarum of Bentham and Hooker' Flourensia was included under Helian­ thus 'with some mention of its peculiarities, while F. corymlJOsa was relegated to Viguiera. In 1883 Gray' discussed the genus, consid­ ering the discoid species typical, suggesting that F. thurifera might be - included as a section" under Bertero & Colla's name (not Cassini's) of Di<nnedea" • and giving the neW name Viguiera poeppigii to F. corymbosa. The genus was again referred to HelianthUB by Baillon • in 1886, but was recognized as distinct by Hoffman' in 1890, and has been retained by all subsequent authors. In 1870 Philippi' described F. hi.pida from Chile, and in the next decade Griesbach published three radiate species, truly referahle to the genus, from Argentina. Philippi ' 8 species, however, repr<>o sen ted in the Berlin Herbarium by an authentic but very poor speci· men, is a Viguiera apparently identical with V. g'illiesii (Hook. & Arn.) Hieron. In 1891 Philippi' published Heliamhus atacamensis, referred to Flourensia by Reiche' in 1905, and in 1895 " several new species --------------------------------------------.
