  • Phylogeny and Systematics of the Rauvolfioideae
    PHYLOGENY AND SYSTEMATICS Andre´ O. Simo˜es,2 Tatyana Livshultz,3 Elena OF THE RAUVOLFIOIDEAE Conti,2 and Mary E. Endress2 (APOCYNACEAE) BASED ON MOLECULAR AND MORPHOLOGICAL EVIDENCE1 ABSTRACT To elucidate deeper relationships within Rauvolfioideae (Apocynaceae), a phylogenetic analysis was conducted using sequences from five DNA regions of the chloroplast genome (matK, rbcL, rpl16 intron, rps16 intron, and 39 trnK intron), as well as morphology. Bayesian and parsimony analyses were performed on sequences from 50 taxa of Rauvolfioideae and 16 taxa from Apocynoideae. Neither subfamily is monophyletic, Rauvolfioideae because it is a grade and Apocynoideae because the subfamilies Periplocoideae, Secamonoideae, and Asclepiadoideae nest within it. In addition, three of the nine currently recognized tribes of Rauvolfioideae (Alstonieae, Melodineae, and Vinceae) are polyphyletic. We discuss morphological characters and identify pervasive homoplasy, particularly among fruit and seed characters previously used to delimit tribes in Rauvolfioideae, as the major source of incongruence between traditional classifications and our phylogenetic results. Based on our phylogeny, simple style-heads, syncarpous ovaries, indehiscent fruits, and winged seeds have evolved in parallel numerous times. A revised classification is offered for the subfamily, its tribes, and inclusive genera. Key words: Apocynaceae, classification, homoplasy, molecular phylogenetics, morphology, Rauvolfioideae, system- atics. During the past decade, phylogenetic studies, (Civeyrel et al., 1998; Civeyrel & Rowe, 2001; Liede especially those employing molecular data, have et al., 2002a, b; Rapini et al., 2003; Meve & Liede, significantly improved our understanding of higher- 2002, 2004; Verhoeven et al., 2003; Liede & Meve, level relationships within Apocynaceae s.l., leading to 2004; Liede-Schumann et al., 2005). the recognition of this family as a strongly supported Despite significant insights gained from studies clade composed of the traditional Apocynaceae s.

The objective of this study was to investigate the efficacy of the plant extracts against selected pathogens that cause human skin disorders and evaluation of the antioxidant capability for validation of folk uses of the plant. Materials and Methods: The agar diffusion and micro-dilution methods were used to determine the antimicrobial activities of the extracts against selected bacteria and fungi. The data were subjected to one way analysis of variance (ANOVA) and Duncan’s Multiple Range Test (DMRT) was used to determine significant differences (p<0.05) among treatment means. Results: The highest antibacterial activity (inhibition zone diameter >19 mm) was obtained with the acetone extract against Pseudomonas aeruginosa, Shigella sonnei, Shigella flexneri, Bacillus cereus, Streptococcus pyogens and Bacillus subtilis; by the ethanol extract against B. cereus. None of the extracts was active against the tested fungi, apart from the acetone extract which showed strong inhibitory activity against Candida glabrata.

National Herbarium of the Netherlands, Wageningen branch, Wageningen University Gen. Foulkesweg 37, 6703 BL Wageningen, the Netherlands Date of publication: 28-09-2001 BACKHUYS PUBLISHERS 2001 EDITORIAL MESSAGE WAgeningen University Papers is the new title of Wageningen Agricultural University Papers, which series was published from 1988 upto 1999 (the last issue was 1999-4: Monopetalanthus exit, by J.J. Wieringa). In the year 2000 no issues were produced. Predeces­ sors of the journal were the Agricultural University Wageningen Papers (1984-1988) and the Mededelingen van de Landbouwhoge- school (te) Wageningen (1918-1983). The publication, a series of irregularly published monographs (some­ times reviews or theses) mainly in the English language (with occasional French language issues), is a medium for larger-sized papers of Wageningen University staff members and their collabo­ rators, working in the fields of plant- and animal sciences. Until 1996 the series was funded centrally by the University, but because of financial considerations this policy has been abandoned. Since then, funding has been rather haphazard. The series has always been used as an official exchange medium for the Central Library of the University, which policy has also been abandoned. The exchange list has been reduced, and in the future the WAUP will be offered for exchange with library partners only on the basis of counter- performance. The Editorial Board is looking for ways to continue the publication of WAUP.

  • Assessment of the Protective Properties of Acokanthera Oblongifolia Plant Extract on Mild Steel in Saline Solution
    International Journal of Pharmacy Practice and Pharmaceutical Sciences , Vol. (2), Issue (1), 2020 ASSESSMENT OF THE PROTECTIVE PROPERTIES OF ACOKANTHERA OBLONGIFOLIA PLANT EXTRACT ON MILD STEEL IN SALINE SOLUTION Einas Bin Sultan1, khawla Areef1,Manar Abazeid1, Muftah Shushni1 ,Elarbi Khalil2, Fathi M Sherif3 Email:[email protected] 1Department ofPharmacognosy,Faculty of Pharmacy, University of Tripoli, Tripoli, Libya. 2Department of Materials and Metallurgical Engineering,Faculty of Engineering, University of Tripoli, Tripoli, Libya. 3Department of Pharmacology, faculty of Pharmacy, University of Tripoli, Tripoli, Libya ABSTRACT: Several plant extracts have recently been reported as inhibitors for metallic materials in corrosive media. Thus, the corrosion inhibition of mild steel in a 3.5% NaCl solution in the presence of different concentrations of Acokanthera oblongifolia extract at a temperature range of 30 to 60 ⁰Cand for various immersion time was studied using weight loss method. The results showed that Acokanthera oblongifolia plant extract exhibit good corrosion inhibition efficiency. The inhibition efficiency of Acokanthera oblongifoliaextract increases with an increase in inhibitors concentration and through immersion periods but decreases with an increase in the temperature. The inhibitory effect could be due to the presence of some phytochemical compounds in the plantwhich is adsorbed on the surface of the mild steel. KEYWORDS: Mild steel, Acokanthera oblongifolia extract, weight loss, corrosion inhibition, adsorption. 1. INTRODUCTION Much research in recent years has been interested in studying the effect of natural plant-sourced products on metals corrosion as green inhibitors, and have confirmed that they have good corrosion inhibition efficacy[1 to 29].This interest in this aspect of the research was the result of the desire to obtain inhibitors that are environmentally friendly, non-toxic and available in large quantities also to avoid the highly toxic effect of some synthetic inhibitors on both environment and human beings.

Introduction Acokanthera schimperi (A. DC.) Schweinf, belonging to the family Apocynaceae, was called "Merenz" locally. It is a well-known East African arrow poison plant and found from Eritrea south to Tanzania and west to Uganda, Rwanda and eastern DR Congo. It is also found in southern Yemen. [1,2]. In Ethiopia, the leaves and bark of A. schimperi were applied to the skin to treat skin disorders, and an infusion of its leaves was gargled to treat tonsillitis [2].

  • Apocynaceae and Asclepiadaceae Evaluated with Rbcl Data
    --.Plant Systematics P1. Syst. Evol. 202:153-175 (1996) and Evolution © Springer-Verlag 1996 Printed in Austria The familial and subfamilial relationships of Apocynaceae and Asclepiadaceae evaluated with rbcL data BENGT SENNBLAD and BIRGITTABREMER Received July 18, 1995; in revised version January 15, 1996 Key words: Gentianales, Apocynaceae, Asclepiadaceae. - Phylogeny, rbcL, parsimony, familial classification, subfamilial classification. Abstract" Sequence data for the rbcL gene from twenty-four taxa of the families Apocy- naceae and Asclepiadaceae were cladistically analysed in order to evaluate the existing familial and subfamilial classification. The taxa sampled represent all described subfami- lies and a majority of the described tribes. The cladistic analysis shows that the Asclepi- adaceae are nested within the Apocynaceae. An amalgamation of the two families is therefore recommended. The subfamilial classification is also in need of revision: the sub- families Plumerioideae and Apocynoideae of the current classifications are paraphyletic, as are many of the tribes. Potential subfamily candidates and characters traditionally used in the classification are discussed. The Apocynaceae and Asclepiadaceae are two relatively large families (in total approximately 5000 species) in the order Gentianales (Asteridae). The current cir- cumscription of the Gentianales was made by WAOENITZ(1959, revised 1992), who included the families Gentianaceae, Rubiaceae (excluded by CRONQUIST 1981), Apocynaceae, Asclepiadaceae, and Loganiaceae (sometimes divided into several families, CRONQUIST 1981, DAHLGREN 1983, TAKHTAJAN 1987, STRUWE & al. 1994). Other families are sometimes also included (see CRONQU~ST 1981, DAHLGREN 1983, TAKHTAJAN 1987, THORNE 1992, NICHOLAS & BAIJNATH 1994). Recent molecular stud- ies (DowNIE & PALMER 1992, OLMSTEAD& al. 1993), however, support the circum- scription proposed by WA~ENITZ.
