Introduction Greek " Phyto" means plant and phytochemicals are usually related to plant pigments. So, fruits and vegetables that are bright colors - yellow, orange, red, green, blue,and purple-generally contain due to the presence of severals phytochemicals and the most nutrients. We can benefit from all of the phytochemicals and nutrients found in plant foods by eating 5-9 servings of fruits and vegetables a day and eating more whole grains, soy and nuts etc. More than 900 different phytochemicals are discovered from plants. In ancient era plants are extensively used for nutrition and remedies of several diseases. Recent research reported to get your Phytos eat 5-9 servings of colorful fruits and vegetables every day. A phytochemical is a natural bioactive compounds found in plant foods, vegetables, nuts, roots, barks that works as nutrients and dietary fiber to protect against disease such as slow the aging process, cancer, heart disease, stroke, high blood pressure, cataracts, osteoporosis, and urinary tract infections. Pronounced "fight-o-chemicals," phytochemicals fight to protect your health. They can have complementary and overlapping mechanisms of action in the body, including stimulation of t he i m mu ne system, antioxidant effects, modulation of detoxification enzymes, antibacterial andantiviral and modulation of hormone metabolism activities ( Aiyelaagbe and Osamudiamen, 2009) and (Egwaikhide et al., 2007). P. cereifera called Candle tree; is a small tree with rough bark belonging to the family Bignoniaceae. The leaves are oblong and acuminate and the flowers are cauliflorous, nocturnal, white, slightly fragrant and calyx spathaceous. The fruits as well as seeds of this tree are berry smooth, pale yellow, candle-like, pendent, edible and used as fodder source. It is native to Panama and cultivated for ornamental uses in many tropical countries (Van Steenis, 1977; Madulid, 2000). As a part of our continuing studies on medicinal plants in Bangladesh, the organic soluble materials of barks of P. cereifera were evaluated for determining phyto-constituents for the first time (Md. Reyad-ul-ferdous et al., 2012). 2. Materials and Methods 2.1. Plant material Plant materials: The Bark of P. cereifera was collected from Mirpur Botanical Garden, Dhaka, Bangladesh, in November 2011. A voucher specimen collected from Bangladesh National Herbarium, Dhaka, Bangladesh (Accession no.36569). The Bark were washed with water to remove all unwanted plant materials and sand, air dried under light exposure (27°C-30°C for 7 days), pulverized in a mill and stored in an airtight container for further use. The air dried and powdered Bark (500 gm) of P. cereifera was macerated in 2.5 L of methanol for 7 days and then filtered through a cotton plug followed by Whatman filter paper number 1. The extract was concentrated with a rotary evaporator at low temperature (40-45 ºC) and reduced pressure. The concentrated methanolic extract (ME) 57 ISSN 2348 – 0319 International Journal of Innovative and Applied Research (2014), Volume 2, Issue (7): 57- 60 was partitioned by modified Kupchan method (Van Wagenen et al., 1993) and the resultant partitionates i.e., pet- ether (PESF), carbon tetrachloride (CTCSF), chloroform (CSF), and aqueous (AQSF) soluble fractions were used for the experimental processes. 2.2. Preparation of extract The powdered crude material (200 g) was extracted thrice in distilled water (5.5 L; 27°C-30°C) on shaker (Stuart Scientific Orbital Shaker, UK) for 48 hours. The extract was filtered using a Buchner funnel and Whatman No.1 filter paper. The filtrate of aqueous extract obtained was quickly frozen at -40°C and dried for 48 h using a freeze dryer (Savant Refrigerated vapor Trap, RV T41404, USA) to give a yield of 30 g of dry extract. The resulting extract was reconstituted with distilled water to give desired concentrations used in this study. 3. Experimental Procedure 3.1. Phytochemical investigation of the plant extract A small portion of the dry methanolic extract was used for several phytochemical tests. Following phytochemicals investigation was conducted in accordance with the methods with little modifications. In present investigation we found several compounds table-1. Phytochemicals are identified by characteristic color changes (Harborne, 1998 and Egwaikhide et al., 2007). 3.1.2. Anthraquinone (Borntrger’s Test) About 0.5 g of the extract was taken into a dry test tube and 5 mL of chloroform was added and shaken for 5 min. The extract was filtered and the filtrate was shaken with equal volume of 10% ammonia solution. A pink violet or red color in the ammonical layer indicates presence of anthraquinone. 3.1.3. Tannins Small quantity of extract was mixed with distilled water and heated on H2O bath. It was filtered and Ferric chloride was added to the filtrate. A dark green color indicates presence of tannins. 5ml of extract and a few drops of 1% lead acetate were added. A yellow precipitate was formed, indicates the presence of tannins. 3.1.4. Flavonoids About 0.2 g was dissolved in diluted NaOH and HCl was added. A yellow solution that turns colorless indicates the presence of flavonoids. 3.1.4. Saponins About 0.2 g of plant extracts was taken and 5 mL of distilled water was added and then boiled. Frothing persistence shows presence of saponins. 3.1.5. Steroids (Libermann- Burchard Reaction) 1ml plant material in 10 mL chloroform filtered. Two hundred milliliter of acetic anhydride was added to 2 mL filtrate with 2 mL H2SO4. The color changes from violet to blue or green in some samples indicating the presence of steroids.1 ml of the extracts was dissolved in 10ml of chloroform and equal volume of concentrated H2SO4 was addwd by sides of the test tube. The upper layer turn red and H2SO4 layer showed yellow with green fluorescence. Which indicate the presence of steroids compounds in barks of P. cereifera. 3.1.6. Phlobatanins About 0.5 g of plant extract was dissolved in distilled water and filtered. The filtrate was boiled with 2% HCl solution and Red precipitate shows that indicate the presence of phlobatanins. 3.1.7. Terpenoids (Salkowski Method) About 0.5 g of each extract in 2 mL of chloroform filtered. Concentrated H2SO4 carefully added to form a layer. A reddish brown color was formed to show positive results for the presence of terpenoids. 58 ISSN 2348 – 0319 International Journal of Innovative and Applied Research (2014), Volume 2, Issue (7): 57- 60 3.1.8. Triterpenoids 10 mg of the extract was dissolved in 1 ml of chloroform; 1ml of acetic anhydride was added following the addition of 2 ml of conc. H2SO4. Formation of reddish violet colour indicates the presence of triterpenoids. 3.1.9. Cardiac Glycoside About 0.5g of each was treated with 2 mL of glacial acetic acid containing a drop of FeCl3 solution. This was under layered with 1 mL of conc. H2SO4 a brown ring obtained at the interface indicated the presence of de-oxy sugar characteristics of cardenolides.

    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.

A small but ecologically and economically important group of plants classified in 28 orders, 67 families and about 528 species of angiosperms are pollinated by nectar-feeding bats. From a phylogenetic perspective this is a derived pollination mode involving a relatively large and energetically expensive pollinator. Here its ecologi- cal and evolutionary consequences are explored. Downloaded from † Scope and Conclusions This review summarizes adaptations in bats and plants that facilitate this interaction and discusses the evolution of bat pollination from a plant phylogenetic perspective. Two families of bats contain specialized flower visitors, one in the Old World and one in the New World. Adaptation to pollination by bats has evolved independently many times from a variety of ancestral conditions, including insect-, bird- and non-volant mammal-pollination. Bat pollination predominates in very few families but is relatively common in certain angiosperm subfamilies and tribes.

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.

  • Preliminary in Vitro Biological and Phytochemical Screenings of Parmentiera Cereifera Seem
    Bangladesh Pharmaceutical Journal 15(2): 103-106, 2012 Preliminary In Vitro Biological and Phytochemical Screenings of Parmentiera cereifera Seem Md. Reyad-ul-Ferdous1, Ridwan Bin Rashid2, Md. Al Amin Sikder3, Fahima Aktar3 and Mohammad A. Rashid3 1Department of Pharmacy, State University of Bangladesh, Dhaka, Bangladesh 2Department of Microbiology, University of Dhaka, Dhaka, Bangladesh 3Department of Pharmaceutical Chemistry, Faculty of Pharmacy, University of Dhaka, Dhaka, Bangladesh Abstract In this present study, the leaf extracts of Parmentiera cereifera were subjected to a comparative evaluation of the antioxidant capacities, phenol and polyphenols content, membrane stabilization, thrombolytic, antimicrobial activities and cytotoxicity to brine shrimps (Artemia salina). When the DPPH (1,1- Diphenyl-2-picryl hydrazyl) radical scavenging effect was determined spectrophotometrically significant radical scavenging property was observed in crude methanol extract (ME) with IC50 of 21.95 µg/ml. Here, butylated hydroxytoluene (BHT) and ascorbic acid (ASA) were used as standard antioxidants. The phenol and polyphenol content of the extractives varied between 56.84 to 89.58 mg of GAE/gm of dried extract. The thrombolytic and membrane stabilizing activities were assessed by using human erythrocyte and the results were compared with standard streptokinase (SK) and standard anti-inflammatory drug, acetyl salicylic acid (ASA), respectively. The extracts demonstrated significant toxicity to A. salina with LC50 values ranging from 6.07 to 7.83 µg/ml as compared to standard Vincristine sulphate (VS, LC50value 0.45 µg/ml). On the other hand, the chloroform soluble fraction (CSF) of methanol extract revealed moderate antibacterial activity against some microorganisms used in the screening. Preliminary phytochemical investigation suggested the presence of flavonoids, saponins, tannins, triterpenoids and steroids.

  • Analysis of Diversity Using Simple Sequence Repeat (SSR): Distinctions Between Original Parmentiera Cereifera Tree and Somaclone
    Elshafei and Esmaiel Bulletin of the National Research Centre (2018) 42:33 Bulletin of the National https://doi.org/10.1186/s42269-018-0037-y Research Centre RESEARCH Open Access Analysis of diversity using simple sequence repeat (SSR): distinctions between original Parmentiera cereifera tree and somaclones Adel Ahmed Elshafei1* and Naglaa Mohamed Esmaiel2 Abstract Background: The possibility of culturing Parmentiera cereifera in vitro was tested. Shoot tips and lateral buds were cultured in three media that were based on Murashige and Skoog (MS) but supplemented with different types and concentrations of growth regulators. Thirty-eight simple sequence repeat (SSR) primers were used to assess the genetic stability of the regenerated plantlets. Results: Lateral buds recorded the highest significant mean values for shoot, root length, and the number of leaves when cultured in MS + 1.2 mg/l of 6-benzylaminopurine (BAP) + 1.5 g/l of activated charcoal. Seeds were also grown in different media. The best results were obtained with MS basal medium. The resulting shoots were rooted in MS medium, with 1.5 g/l of activated charcoal. Regenerated plants were acclimatized in the greenhouse. The 38 SSR primers produced 63 scorable bands ranging from 1 to 3, with an average of 1.68 per primer. Fifty-five monomorphic bands were obtained that ranged from 0 to 3, with an average of 1.45 per primer. The coefficient of similarity matrix ranged from 0.92 to 1.0, with an average of 97.4. Dendrogram generated using the SSR data tended to group the in vitro plants with the mother plant into two major clusters.

TRIVZDI, SHebA AND VEronA ~A Department of Botany, Punjabi University, Patiala 147002 MS received 1 September 1976; in revised form 14 October 1976 ABSTRACT The petiolar anatomy of sixteen species belonging to iourteen genera of Bignoniaceae has been studied. Two aspects, namely, the vascular pattern in the slender part of the petiole and the mode of vascular supply from the primary rachis to leaflets or secondary rachii, are taken into consideration. On the basis of the ~asculature as seen in tran.,ecticn of the slendeI part, four main types of petioles have been recognized, while thereare three patterns of vascular supply. A key also has been devised to identify these sixteen species. 1. INTRODUCTION PETIOLAR anatomy has received considerable attention of anatomists from time to time. One of the most comprehensive works on this aspect is by Watari} on Leguminosae. Howard ~' also has surveyed the petiole vasculature i n a large number of dicot families and found this structure to be of great taxonomic value. Carlquist 3 favoured correlated study of node-petiole structure. Howard ~ also advocated the study of the stem node-leaf-continuum The present study deals with the petiolar anatomy of certain Bignoniaceous members. The nodal anatomy of some members has already been studied by the present authors. 5 2. MATERIALSAND METHODS Materials for the present study were collected from plants growing in the Botanical Garden and the University Campus.
