  • Introduction
    INTRODUCTION Section I: Bioactive Molecules from Mimusops elengi & Artemisia pallens Section II: Characterization of Molecules by Single Crystal X- Ray Diffraction Section I Bioactive Molecules from Mimusops elengi & Artemisia pailens 1.1 Ayurveda - The Art of Life Man has sought out plants with medicinal properties since ancient times. Evidence of this is the thousand years old traditions and records of proper healing. Traditional medicine (also known as indigenous or folk medicine) comprises medical knowledge systems that developed over centuries within various societies before the era of modern medicine. Traditional medicines include Unani system in Greece, Ayurvedic system in India, Amachi in Tibet, traditional Chinese medicine in China, Siddha or more recently Homoeopathy in Germany. Researchers are investigating not only the classical plants but also the related species that may contain similar active constituents as well as hitherto unknown plants which have no previous history of medicinal use\ Ayurveda is a holistic system of medicine from India that uses a constitutional model. Its aim is to provide guidance regarding food and lifestyle so that healthy people can stay healthy and folks with health challenges can improve their health. Ayurveda is an intricate system of healing that originated in India thousands of years ago. Vast ethno botanical knowledge exists in India from ancient time. Written records of the use of plants for curing human or animal diseases in India can be traced back to the earliest (4500-1600 BC) scripture of the Hindus, the Rigveda. Ayurveda, the Indian indigenous system of medicine dating back to Vedic ages (1500-800 BC), has been the integral part of Indian culture.

Different cross sections were placed randomly along different ecological sites. In each different habitat types plant species were recorded and sampled by using quadrates 25 by 25 m, and then most rare and endangered species were identified according to the percentage of frequency. In this investigation 46 rare and endangered plant species belongs to 33 families and 41 genera in which 10 endemic to Arabian Peninsula were identified and documented. Names of plants, frequency percentage and density per hectare were gathered. The distribution of rare species, patterns of some most rare and endangered plant species were mapped by using ARC-GIS techniques.

    Sapienza University of Rome ARCHMAT (ERASMUS MUNDUS MASTER IN ARCHAEOLOGICAL MATERIALS SCIENCE) Scienze e Tecnologie per la Conservazione dei Beni Culturali Study and Investigations of Archaeobotanical remains from Tutankhamun tomb NagmEldeen Morshed Hamza [email protected] 1905033 Relator: Prof. Laura Sadori Dipartimento di Biologia Ambientale Università degli Studi di Roma "La Sapienza" Supervisor Prof.Laura Sadori Sapienza University Rome, September 2020 1 Abstract An immense ―natural‖ treasure was recently recovered from the storerooms of the Archaeological Museum of Cairo. Once moved to the new seat and museum, the Grand Egyptian Museum, it was time to start studying this precious ―rubbish‖ recovered one century ago, at the end of the archaeological excavation of the tomb of Pharaoh Tutankhamun by Howard Carter‘s team. The study focuses on carpological remains swiped from the surfaces of the tomb and deposited in a wooden box in 1933. The carpological remains retrieved from the box are still in excellent condition, and allowed identification at a species level. Identified remains contained fruits and seeds belonging to 24 species belonging to 14 different plant families. New Species found in all the tombs of the Eighteenth Dynasty include faba bean (Vicia faba L.) and onion (Allium cepa L.). Egyptian luffa / sponge gourd (Luffa aegyptiaca Mill.) is a total novelty. In this work I started analyzing the plant remains, using only a qualitative approach. The restrictions caused by the pandemic prevented, in fact, a continuous laboratory work and the complete identification of the so far extracted macroremains.

Friis is the largest tree species in the Arabian Peninsula and a characteristic species of the threatened 100 individuals that currently remained only at eleven localities. We determined the rbcL (ribulose-1, 5-bisphosphate carboxylase/oxygenase large subunit) gene sequence, current phylogenetic status and RAPD (Random Amplification of Polymorphic DNA) fingerprinting pattern of this regionally endangered plant species. Overall rbcL gene sequence similarity among the 18 plant species under the family Sapotaceae was very high (99.8%). The plastid rbcL gene sequence of M. laurifolia was identical to that of M.

    INTERNATIONAL TROPICAL TIMBER ORGANIZATION ITTO PROJECT DOCUMENT TITLE: TIMBERS OF TROPICAL AFRICA PART 2: GROUP 7(2) WITHIN THE PROTA PROGRAMME SERIAL NUMBER: PD 479/07 Rev.2 (M) COMMITTEE: ECONOMIC INFORMATION AND MARKET INTELLIGENCE SUBMITTED BY: GOVERNMENT OF GHANA ORIGINAL LANGUAGE: ENGLISH BACKGROUND: As part of a total programme to improve the access to information on the 7000 useful plants of Tropical Africa and to promote their use in a sustainable manner, PROTA (Plant Resources of Tropical Africa) will make a synthesis of all existing but dispersed knowledge on the estimated 1070 ‘Timbers of Tropical Africa’ (Commodity group 7) in two Parts. This document concerns the second sub-project, on the 570 ‘Timbers of Tropical Africa’ from currently less important timber-producing taxonomic families (Commodity group 7(2)). It is preceded by a sub-project on the 500 ‘Timbers of Tropical Africa’ from the currently more important timber-producing taxonomic families (Commodity group 7(1); ITTO Project PD 264/04 Rev. 3 (M,I)). PROTA is strongly rooted in the group that successfully delivered the ITTO-funded PROSEA ‘Timber trees’ Handbook volumes.

As a result, no comprehensive Ericales time-calibrated tree or biogeographical analysis of the order has been published. Here, we elucidate phyloge- Long distance dispersal netic relationships within the order and then conduct time-dependent biogeographical and diversification Supermatrix analyses by using a taxon and locus-rich supermatrix approach on one-third of the extant species diversity
