Don) Melch Flower Extract Against MCF-7 Cell Line R.Vidhya* and Dr. Albin T. Fleming P.G. & Research Department of Advanced Zoology & Biotechnology, Loyola College, Nungambakkam, Chennai-600082, Tamil Nadu, India *Corresponding author e-mail: [email protected] ABSTRACT Objective: Bignoniaceae is a family having 100 genera of flowering plants. This family has many species with effective cytotoxic activity. One of its genuses, Tecoma contains 14 species and they are referred as trumpet trees. Tecoma species has various uses recorded in folk medicine and are being explored scientifically. Flowers of one of the species T.castanifolia is assessed for its potential. Method: Fresh and healthy flowers were collected and were cold extracted with solvents viz., chloroform, ethyl acetate and methanol; filtered through Whatmann No.1 filter paper and evaporated to dryness. The extracts were subjected to MTT assay against MCF-7 cell line. Result: The extraction yielded a gummy extract which were stored in a glass vial. The preliminary data shows that of the extracts tested the ethyl acetate extract has the highest cytotoxic activity in vitro against MCF-7 cell line. The 50% growth inhibition concentration of the ethyl acetate extract was obtained at 180µg/ml. Concluison: The study shows that the ethyl acetate extract has fair cytotoxicity and can be tested with other cell lines. Further, studies pertaining to their composition of phytochemicals etc need to be done. Keywords- Plant extract, Cytotoxicity, MCF-7, MTT assay, Tecoma.

El bosque seco tropical es considerado uno de los ecosistemas con mayores niveles de fragmentación y exclusividad biológica. En Colombia, se estíma que cerca del 33% de las coberturas actuales de bosque seco son rastrojos, el 33% bosques secundarios y tan solo el 24% bosques maduros. Lo que se traduce en un porcentaje muy reducido de bosques conservados respecto su distribución original (menos del <5%). Lo anterior sumado al bajo nivel conocimiento que se tiene sobre este ecosistema, recaba en la necesidad de proponer estrategias que promuevan la generación de datos científicos útiles para la gestion integral de los bosques secos del territorio nacional.

  • Bignoniaceae)
    Systematic Botany (2007), 32(3): pp. 660–670 # Copyright 2007 by the American Society of Plant Taxonomists Taxonomic Revisions in the Polyphyletic Genus Tabebuia s. l. (Bignoniaceae) SUSAN O. GROSE1 and R. G. OLMSTEAD Department of Biology, University of Washington, Box 355325, Seattle, Washington 98195 U.S.A. 1Author for correspondence ([email protected]) Communicating Editor: James F. Smith ABSTRACT. Recent molecular studies have shown Tabebuia to be polyphyletic, thus necessitating taxonomic revision. These revisions are made here by resurrecting two genera to contain segregate clades of Tabebuia. Roseodendron Miranda consists of the two species with spathaceous calices of similar texture to the corolla. Handroanthus Mattos comprises the principally yellow flowered species with an indumentum of hairs covering the leaves and calyx. The species of Handroanthus are also characterized by having extremely dense wood containing copious quantities of lapachol. Tabebuia is restricted to those species with white to red or rarely yellow flowers and having an indumentum of stalked or sessile lepidote scales. The following new combinations are published: Handroanthus arianeae (A. H. Gentry) S. Grose, H. billbergii (Bur. & K. Schum). S. Grose subsp. billbergii, H. billbergii subsp. ampla (A. H. Gentry) S.

Exotic plant invasions have significantly 9 altered the native floral communities because of invasive giant reed, with potential impacts to the 10 native wildlife using resources in the riparian corridor. This study was conducted along a 3.22 11 km stretch of the LRGR in southwestern Webb County, TX to assess bee (Anthophila) 12 communities and their flowering-plant resources among proximal and distal terrestrial upland 13 and river-adjacent sub-corridors. Patterns related to the bee community across the two habitats 14 consisted of low variation and dominance by common taxa, suggesting the riparian corridor 15 could be used as a resource for bee foraging and soil-nesting.

Locally known as Rohida, Roheda in Hindi, Rakhtroda in Marathi, Dadimacchada, Chalachhada, Dadimapuspaka in Sanskrit mostly found in the Thar desert regions of India and Pakistan. The plant holds tremendous potential of EVIEW medicinal value and is used in traditional and folklore system of medicines. It has been used traditionally in various ailments like syphilis, swelling, leucorrhoea and leucoderma, enlargement of spleen, obesity, tumours, blood disorders, flatulence and abdominal R pain. Tecomella undulata has gained prominence due to presence of some prominent secondary metabolites of great therapeutic potential like stigmasterol, β-sitosterol, α-lapachone, tectol isolated from heartwood, bark and leaf.

The Spanish name roble de sabana, meaning "savannah oak", is widely used in Costa Rica, probably because it often remains in heavily deforested areas and because of the resemblance of its wood to that of oak trees.[3] It is the national tree of El Salvador, where it is called "Maquilíshuat".

Similar species Summary Tabebuia heterophylla is a small to medium sized deciduous tree attaining a height of 18m. In its native range it is widespread in abandoned pastures and secondary forests. It has become a problem in Pacific regions and is particularly common in dry, coastal woodlands and in secondary forests. It grows on any soil type and will adapt to poor or degraded soils. T. heterophylla regenerates and forms pure monotypic stands. It is an extremely fast growing species and can easily outcompete native and other exotic trees. It bears leaves and branches almost to the base and casts a deep shade under which virtualy no other species can grow. Its thick litter layer may also prevent the growth of native seedlings. view this species on IUCN Red List Species Description T. heterophylla is a small- to medium-size tree attaining a height of 18m and a diameter of 60cm. It has a furrowed bark, and a narrow, columnar crown, with opposite, palmately compound leaves. There are 3-5 leaflets, with blades elliptic to oblanceolate or obovate, 6-16cm long, leathery, acute to blunt at the tip, acute to rounded or oblique at the base; surfaces glabrous; margins entire; petiole 3-12cm long.

Updated: 12 April, 2016 A Synoptical Classification of the Lamiales Version 2.6.2 (This is a working document) Compiled by Richard Olmstead With the help of: D. Albach, P. Beardsley, D. Bedigian, B. Bremer, P. Cantino, J. Chau, J. L. Clark, B. Drew, P. Garnock- Jones, S. Grose (Heydler), R. Harley, H.-D. Ihlenfeldt, B. Li, L. Lohmann, S. Mathews, L. McDade, K. Müller, E. Norman, N. O’Leary, B. Oxelman, J. Reveal, R. Scotland, J. Smith, D. Tank, E. Tripp, S. Wagstaff, E. Wallander, A. Weber, A. Wolfe, A. Wortley, N. Young, M. Zjhra, and many others [estimated 25 families, 1041 genera, and ca. 21,878 species in Lamiales] The goal of this project is to produce a working infraordinal classification of the Lamiales to genus with information on distribution and species richness. All recognized taxa will be clades; adherence to Linnaean ranks is optional. Synonymy is very incomplete (comprehensive synonymy is not a goal of the project, but could be incorporated). Although I anticipate producing a publishable version of this classification at a future date, my near- term goal is to produce a web-accessible version, which will be available to the public and which will be updated regularly through input from systematists familiar with taxa within the Lamiales. For further information on the project and to provide information for future versions, please contact R. Olmstead via email at [email protected], or by regular mail at: Department of Biology, Box 355325, University of Washington, Seattle WA 98195, USA.
