Introduction
Introduction 1.1-General overview Flavonoids are a large group of phenolic plant constituents. To date, more than 8000 flavonoids have been identified1 , although a much smaller number is important from a dietary point of view. That flavonoids possess bioactive potential has been recognized for long, but until recently, data about their bioavailability, metabolic fate, and health effects were limited. In the 1990s, interest in these compounds truly commenced and has been growing ever since. Flavonoids are potent antioxidants in vitro, and therefore one of the main interests in thecompounds has involved protection against cardiovascular disease. Antioxidation is, however,only one of the many mechanisms through which flavonoids could exert their actions. Flavonoids are divided to several subgroups, and it is important to keep in mind that thebiological and chemical properties of flavonoids belonging to different subgroups can be quite different. Flavonoids consist of 2 benzene rings (A and B), which are connected by an oxygen-containing pyrene ring (C) as shown below: 1 Flavonoids containing a hydroxyl group in position C-3of the C ring are classified as flavonols . Beside this class flavonoids are generally classified into : flavones, chlacones, aurones, flavanones, isoflavones, dihydroflavonols, dihydrochalcones, catechins(flavans) and anthocyanins. The general structures of such classes are outlined in scheme I. Further distinction within these families is based on whether and how additional substituents (hydroxyls or methyls, methoxyls …etc) have been introduced to the different positions of the molecule.In isoflavonoids, the B ring is bound to C-3 of ring C (instead of C-2 as in flavones and flavonols). -

In 2000 he organized a tour of Ethiopia for a group of friends. They traveled all over the country and observed a number of wonderful plant habitats. Ethiopia is a fascinating country with a long history of having never been colonized by a European power. The country includes many interesting tribes in the Omo River Valley, intriguing monuments in the north, and unusual Christian churches in the Lalibela area. Theirs is a rich Moslem culture as well.

Result of this part includes their chemical constitutes and use in the different body disorders other than diabetes. 48 plants species are collected from the available literature and presented in the form of a checklist. The second part of this work is a qualitative phytochemical screening of seeds selected from the family Fabaceae, namely: Bauhinia rufescens, Senna alexandrina, Cicer arietinum, Lupinus albus, and Trigonella foenum-graecum. The studied plants are extracted in petroleum ether, water, and ethanol and different phytochemicals are detected in the extract. Alkaloids are present in all plants in the different extract, but their concentration is high in T. foenum-graecum and B. rufescens. Glycosides are highly detected in S. alexandrina and L. albus. Flavonoid is highly detected in B. rufescens, Senna and C. arietinum, and L. albus. Phenolic compound is not detected in all extract of the five plants. Saponin is observed in all plant put highly detected in L. albus. Tannin detected in Senna alexandrina. Resins are observed in plants but highly detected in C. -

PhytoKeys 9: 15–179. doi: 10.3897/phytokeys.9.2279 Abstract Th e Department of Ñeembucú is one of the least well-documented areas of eastern Paraguay, and the fl ora is composed of a mixture of forest and Chaco elements. Regions like Ñeembucú are often considered of lower diversity and interest that more forested regions; this results from both actual species richness fi gures and from under-collecting due to perception as uninteresting. We present here a checklist of the vascular plants of Ñeembucú, which includes 676 taxa (including infraspecifi c taxa and collections identifi ed only to genus) in 100 families and 374 genera. Four hundred and thirty nine (439) of these are new records for Ñeembucú and of these, 4 are new published records for Paraguay. -

Nat. Croat. Vol. 27, No. 2, 407- 420*, 2018, Zagreb. In this paper, the plant lists of glasshouse succulents grown in the Botanical Garden from 1895 to 2017 are studied. Synonymy, nomenclature and origin of plant material were sorted. The lists of species grown in the last 122 years are constructed in such a way as to show that throughout that period at least 1423 taxa of succulent plants from 254 genera and 17 families inhabited the Garden’s cold glass- house collection.

An Alphabetical List of Bromeliad Binomials
AN ALPHABETICAL LIST OF BROMELIAD BINOMIALS Compiled by HARRY E. LUTHER The Marie Selby Botanical Gardens Sarasota, Florida, USA ELEVENTH EDITION Published by the Bromeliad Society International June 2008 ii INTRODUCTION TO EDITION XI This list is presented as a spelling guide for validly published taxa accepted at the Bromeliad Identification Center. The list contains the following information: 1) Genus number (the left-hand number) based on the systematic sequence published in the Smith & Downs monograph: Bromeliaceae (Flora Neotropica, number 14, parts 1-3; 1974, 1977, 1979). Whole numbers are as published in the monograph. 2) Species number (the second number) according to its systematic position in the monograph. Note: Taxa not included in the monograph or that have been reclassified have been assigned numbers to reflect their systematic position within the Smith & Downs framework (e.g., taxon 14.1 is related to taxon 14). The utility of this method is that one may assume for example that Tillandsia comarapaensis (150.2) is related to T. didisticha (150) and therefore may have certain horticultural qualities in common with that species. 3) Genus and species names follow the respective numbers. 4) Subspecific taxa (subspecies, varieties, forms) names are indented below the species names. Note: Variety "a" (the type variety) is not listed unless it contains a form (see Aechmea caudata ). Similarly, the type form is not listed. 5) Author name follows the specific and subspecific names. These names are included for the convenience of specialist users of the list. This list does not contain publication data or synonymy, as it is not our intent for it to be a technical nomenclatural guide. -

Coyoacán, 04510 México, D.F. 2 Escuela Nacional de Ciencias Biológicas, IPN. Apdo. Postal 17-564, Del. M. Hidalgo, I 1410 México, D.F. Resumen. Se muestra la distribución de las familias Agavaceae y Nolinaceae en América y México. Para México se determinó la presencia de 402 taxa, 342 de ellos pertenecen a los géneros Agave, Beschorneria, Furcraea, Hesperaloii, Manfreda, Polianthes, Prochnyanthes y Yucca de la familia Agavaceae, en tanto que 60 corresponden a los géneros Beaucarnea, Calibanus, Dasylirion y Nolina de la familia Nolinaceae. Se presenta también la lista actualizada de las especies de ambas familias, ordenadas alfabéticamente. Para cada taxon se señala su distribución por estado y por provincia florística. Los estados más ricos son: Oaxaca con 63 taxa, Durango con 52, Puebla con 50, San Luis Potosí y Sonora con 47 y Chihuahua con 45. En cuanto a las provincias florísticas con un número mayor de taxa están: las Serranías Meridionales, Sierra Madre Occidental y Altiplanicie. Para México, hasta el momento, se han realizado cinco floras regionales y cuatro listados florísticos, en los que se aborda el estudio de las Agavaceae y Nolinaceae a diferentes niveles. Los géneros Agave, Beaucarnea, Beschorneria, Ma11freda y Prochnyanthes han sido objeto de tratamientos taxonómicos; otros como Dasylirion, Furcraea y Polianthes se encuentran en diferentes etapas de desarrollo, en tanto que Calibanus, Hesperaloii, Nolina, Yucca y varios grupos de Agave, requieren una revisión actualizada. -
