Abstract:

Acanthaceae has received considerable taxonomic attention at the familial, subfamilial, tribal and subtribal levels. Several different infra-familial classifications have been proposed for the Acanthaceae, but no taxonomic consensus has yet been reached. The main objective of the present study is to throw light on the phenetic relationships and to explore the contribution of morphological and molecular characters in systematics of Acanthaceae. The morphological data viz. macromorphology, stomatography, lamina architecture and ISSR profiles of 30 Egyptian acanthaceous taxa were investigated. The phenetic analysis using NTSYS-PC version 2.02 software based on 55 potentially informative morphological and molecular characters indicated that the used morphological and ISSR criteria is likely to be useful and valuable taxonomic traits. The morphological characters and ISSR aspects of all the studied species produced a phenogram that showed two series; one of them had two subseries, the first one comprised only three taxa while the second divided into two clusters, each contained two groups. The delimitation and the membership of the studied taxa clearly merit additional study using more criteria. The phenetic analysis of both morphological and molecular attributes clarified the segregation of genus Avicennia as a distinct identity away from Acanthaceae. Acanthus mollis & A. montanus are isolated in its own series that comparable to tribe Acantheae of the current taxonomic systems. The studied species of Thunbergia are gathered its own subseries that comparable to tribe Thunbergiae and Ruellia in its own group that comparable to tribe Ruellieae.

Ruellia simplex, an older and overlooked name for Ruellia tweediana and ruellia coerulea (Acanthaceae)
Ezcurra,Cecilia; Daniel,Thomas F.;
Darwiniana , 2007,
Abstract: ruellia simplex, the name of a species of ruellia described from cuba in 1870, is the oldest name for the neotropical species generally known as ruellia tweediana, ruellia coerulea and ruellia malacosperma. therefore ruellia simplex has priority and reduces tha latter names to synonym. this species has an amphitropical distribution in the new world, being found in southern united states, mexico and the antilles, and in western bolivia, southwestern brazil, paraguay, uruguay, and northeastern argentina.
Novas espécies de Staurogyne Wall. (Acanthaceae) para o Brasil
Braz, Denise Monte;Monteiro, Reinaldo;

Abstract: the genus staurogyne wall. comprises about 140 tropical species, and in the neotropics 28 species are recognized, especially found in preserved forested areas. a recent revision of the genus for the americas revealed four new species in brazil, which are here described. the new taxa are known from goiás, minas gerais, espírito santo, s?o paulo, rio de janeiro, paraná and santa catarina states, three of them occurring in the atlantic rain forest, and one in the gallery forests of the cerrado domain.

Kurtziana , 2006,
Abstract: Se registra por primera vez la presencia en Argentina de Dicliptera cochabambensis Lindau, hasta ahora considerada como endémica del centro y Sur de Bolivia. En base al material proveniente de la provincia de Salta, se ilustra por primera vez y se describe la especie. Dicliptera cochabambensis Lindau, a species only known from Central and Southern Bolivia, is now recorded for the northwestern Argentina (Salta). Based in the argentine material, the species is illustrated for the first time and described.

A SHORT REVIEW ON UN-EXPLORED MEDICINAL PLANT: ECBOLIUM VIRIDIE
A. Elumalai,M. Chinna Eswaraiah,M. Lakshmi
International Journal of Research in Ayurveda and Pharmacy , 2011,
Abstract: Medicinal plants are the nature’s gift to human being to make disease free healthy life. It plays a vital role to preserve our health. In our country more than 2000 medicinal plants are recognized. Ecbolium viridie (Acanthaceae) is one of the important medicinal plant in India and Malaysia. Some of its medicinal uses have been mentioned in traditional system of medicine such as ayurveda, siddha and unani. This review attempts to encompass the available literature of Ecbolium viridie with respect to its traditional uses and summary of its pharmacological activities.
Immature stages of the Brazilian crescent butterfly Ortilia liriope (Cramer) (Lepidoptera: Nymphalidae)
Silva, PL;Oliveira, NP;Barbosa, EP;Okada, Y;Kaminski, LA;Freitas, AVL;
Neotropical Entomology , 2011, DOI: 10.1590/S1519-566X2011000300006
Abstract: we provide the first information on the morphology of the immature stages (egg, larva, and pupa), oviposition and larval behavior, and host plant, for the brazilian crescent butterfly ortilia liriope (cramer), based on material from santarém municipality, pará state, northern brazil. females of o. liriope lay eggs in clusters. after hatching, larvae eat the exochorion and remain gregarious in all but the final instar. the host plant recorded in the study site is justicia sp. (acanthaceae). despite the scarcity of data on the immature stages of neotropical melitaeini, we can already say that some morphological and behavioral traits observed in the immature stages of o. liriope are also present in all known genera in this tribe.

Chemical constituents and biological activities of species of Justicia: a review
Corrêa, Geone M.;Alcantara, Ant?nio F. de C.;
Revista Brasileira de Farmacognosia , 2012, DOI: 10.1590/S0102-695X2011005000196
Abstract: the acanthaceae family is an important source of therapeutic drugs, and the ethnopharmacological knowledge of this family requires urgent documentation as several of its species are near extinction. justicia is the largest genus of acanthaceae, with approximately 600 species. the present work provides a review addressing the chemistry and pharmacology of the genus justicia. in addition, the biological activities of compounds isolated from the genus are also covered. the chemical and pharmacological information in the present work may inspire new biomedical applications for the species of justicia, considering atom economy, the synthesis of environmentally benign products without producing toxic by-products, the use of renewable sources of raw materials, and the search for processes with maximal efficiency of energy.
Efectos sobre el sistema nervioso central del extracto etanólico y fracciones de Hygrophila tyttha Leonard
Ariza,Sandra Y; Rincón,Javier; Guerrero,Mario F;
Revista Colombiana de Ciencias Químico - Farmacéuticas , 2006,
Abstract: the central nervous effects elicited by the ethanolic extract and the aqueous, chloroformic, methanolic and hexanic fractions obtained from hygrophila tyttha were evaluated in icr mice. to achieve this objective, tests to prove anxiolytic (elevated plus-maze), antidepressant (forced swimming), anticonvulsant (pentylenetetrazol, electroshock), and hypnotic (pentobarbital induced sleep) activity were applied. a bioguided phytochemical study was carried out to determine the most active fractions. according to the high protection scores obtained by the electroshock model (90%) and the activity registered by the elevated plus maze (comparable to diazepam), the chloroformic fraction possibly contains the main active compounds, such as coumarins, flavonoids, steroids and/or terpenoids and saponins, according to the phytochemical analyses. these results support the ethnobotanical use and the therapeutic potential of hygrophila tyttha as a natural source of therapeutic compounds for the treatment of central disorders like anxiety and seizures.
