Six cytotoxic extracts and one potential antimalarial were selected for fractionation, and yielded a number of bioactive compounds which were characterized by spectroscopy methods. Craspidospermum verticillatum (Apocynaceae) yielded four known indole alkoids. Casimirella sp (Icacinaceae) gave three new and five known diterpenoids. Pentopetia androsaemifolia (Apocynaceae) afforded one new and three known cardenolide glycosides. Physalis angulata (Solanaceae) yielded seven known physalins. Roupellina boivinnii (Apocynaceae) yielded four known and three new cardenolide glycosides, and three known cucurbitacins were isolated from Octolepis aff. dioica (Thymelaeaceae). In addition to these structural studies, a synthetic approach to lucilactaene, a cell cycle inhibitor was developed.

E mail id: [email protected] Received: 14 March 2020 Revised and Accepted: 8 July 2020 I. INTRODUCTION: Plants are living factories producing thousands of secondary metabolites. We have a general concept that plants and plant products are harmless. However, more than 700 plants produce physiologically active toxic substances, sufficient to cause harmful effects in human beings and animals. In some plants, one part may be edible while another is poisonous. Lack of toxicological evaluation of natural products leads to the false concept that natural products are safe. Even herbal food ingredients may contain some Phyto-constituents known to produce genotoxic or carcinogenic components after prolonged dose depended exposure. Poisonous plants produce several toxic substances at various concentrations at different organs and cause responses ranging from mild nausea to mortality. Certain animal species may have a specific vulnerability to a potentially poisonous plant. Plant toxins belong to different categories. The reviewed plants are classified into nine based on the significant category of poisons: 1. Plants with Anticholinergic (Antimuscarinic) Poisons: Neurotransmitter acetylcholine transmits impulses between nerves in the brain and neuromuscular junctions. Tropane alkaloids present in plants resembles acetylcholine and hence competitively inhibit acetylcholine receptors producing the anticholinergic syndrome. Their reaction may affect the heart rate, respiration and functions of the central nervous system. -

การเกษตรราชภัฏ RAJABHAT AGRIC. 15 (1) : 16-21 (2016) Effect of Suicide Tree Crude Extract (Cerbera odollam Gaerth.) on Common Cutworm (Spodoptera litura Fabricius) Phanatchakon Somsroi1 and Sukanda ChaiyongAbstract1 Common cutworm (Spodoptera litula Fabricius) is an insect pest which widely spread and damaged the many important crops in Thailand. The purpose of this research was to study the effect of crude extract from Suicide Tree (Cerbera odollam Gaerth.) on control of the third instar larva of common cutworm. The insecticidal efficacy against common cutworm larva was tested using Leaf dipping method and Topical application method. The result showed that at 30% (w/v) of Suicide Tree fruit crude extract displayed strong antifeedant activity, whereas the lower concentration and Suicide Tree leaf crude extract had no effect. In addition, the percentage of mortality from the Suicide Tree fruit crude extract at the concentration of 1, 5, 10 and 30% were 13.33, 80.00, 93.33 and 100% respectively, with LC50 value at 24 hour was 2.68+0.37%. From our results, it was interesting to note that the Suicide Tree fruit crude extract has a strong insecticidal efficiency and should be applied further for control of insect pest.

Question Of the Day Archives: Monday, December 5, 2016 Question: Calcium oxalate is a widespread toxin found in many species of plants. What is the needle shaped crystal containing calcium oxalate called and what is the compilation of these structures known as? Answer: The needle shaped plant-based crystals containing calcium oxalate are known as raphides. A compilation of raphides forms the structure known as an idioblast. (Lim CS et al. Atlas of select poisonous plants and mushrooms. 2016 Disease-a-Month 62(3):37-66) Friday, December 2, 2016 Question: Which oral chelating agent has been reported to cause transient increases in plasma ALT activity in some patients as well as rare instances of mucocutaneous skin reactions? Answer: Orally administered dimercaptosuccinic acid (DMSA) has been reported to cause transient increases in ALT activity as well as rare instances of mucocutaneous skin reactions. (Bradberry S et al. Use of oral dimercaptosuccinic acid (succimer) in adult patients with inorganic lead poisoning. 2009 Q J Med 102:721-732) Thursday, December 1, 2016 Question: What is Clioquinol and why was it withdrawn from the market during the 1970s? Answer: According to the cited reference, “Between the 1950s and 1970s Clioquinol was used to treat and prevent intestinal parasitic disease [intestinal amebiasis].” “In the early 1970s Clioquinol was withdrawn from the market as an oral agent due to an association with sub-acute myelo-optic neuropathy (SMON) in Japanese patients. SMON is a syndrome that involves sensory and motor disturbances in the lower limbs as well as visual changes that are due to symmetrical demyelination of the lateral and posterior funiculi of the spinal cord, optic nerve, and peripheral nerves. -

Cerberiopsis Candelabrum Vieill
ADANSONIA,ser. 2, 11 (4) 1971. UNE APOCYNACÉE MONOCARPIQUE DE NOUVELLE-CALÉDONIE CERBERIOPSIS CANDELABRUM VIEILL. par J. M. VEILLON~ RBSUMÉ: Chez les Dicotylédones, les espèces arborescentes monocarpiques jusqu'à présent connues sont peu nombreuses et dans la quasi-totalité des cas, ce sont des espèces monocaules, leur croissance étant conditionnée par le fonctionnement d'un seul méristème apical dont la différenciation en inflorescence terminale entraîne la mort de la plante. P. SARLIN(1954) a signalé pour la première fois le caractère monocarpique chez l'Apocynacée arborescente : Cerberiopsis candelabrum Vieill.. espèce possédant un nombre élevé mais limité de méristèmes latéraux dont le fonctionnement a pour effet d'engendrer de nombreuses ramifications. Dans cette note, nous présentons quelques données nouvelles relatives 2 l'archi- tecture et à la monocarpie de cette espèce remarquable. SUMMARY:The few monocarpic arborescent dicotyledons already known are almost all monocaul species, their growth being conditioned by the activity of a single apical meristem whose differentiation into a terminal inflorescence leads to the death of the plant. Monocarpy in the tree Cevberiopsis candelabrum Vieill,, was first reported by SARLIN(1954). The species has a large but limited number of lateral meristems whose activity produces numerous branches. We present in this note some recent data concerning the architecture and the mono- carpy of this remarkable species. On sait que la flore néo-calédonienne est particulièrement riche en espèces ayant des formes architecturales ou des biologies très originales. Une des plus remarquables est Cerberiopsis candelabrum Vieill., Apocynacée arborescente dont le caractère monocarpique a été signalé pour la première fois par P.
