  • Genetic Diversity of Selected Apocynaceae Species Based on Chloroplast Gene Rps11

Accepted 22 July, 2011 Apocynaceae is an important family due to its credible therapeutic importance and it is widely distributed in tropics and subtropics. Some species of Apocynaceae have been randomly chosen from different regions of Pakistan for the present study. The main objective was to analyze genetic diversity among seven species using cleaved amplified polymorphic sequences (CAPS) technique on a plastid gene encoding ribosomal protein of smaller subunit 11 (rps11). For this purpose, DNA was extracted from young leaves and with the help of a pair of primer, rps11 gene was amplified and seven restriction enzymes namely: TscAI, ScrfI, DpnI, BsiKHAI, MseI, HinfI, BseGI were used to digest the amplified rps11 gene. The results produced were in the form of bands on gels revealing the length of fragments produced after cutting with restriction enzymes. The digested fragments were found to produce monomorphic bands whereas some polymorphic bands were also observed. On the basis of restricted fragments, phylogenetic tree was prepared depicting different number of clusters with varied level of similarity coefficients. It was observed that the species have shown mixed pattern and closely related species appeared at higher genetic distances.

  • FINAL REPORT NAMIBIA BBI SSFA April 2020 Development of Institutional Synergy to Enable Inventorying and Cultivation of Priorit
    P1-33BEL-000177 – Final Report FINAL REPORT NAMIBIA BBI SSFA April 2020 Development of Institutional Synergy to Enable Inventorying and Cultivation of Priority Species for Conservation in the Southern Africa Region: Medicinal Plants in the Apocynaceae Family The overall objective of this Project is to foster long-term cooperation between key and relevant Institutions in Southern Africa on addressing the unsustainable exploitation of medicinal plants in the Region. The initial focus is a group of plants in the Apocynaceae family that recently became popular in northern Namibia. The project endeavours to i) Conduct traditional and molecular-based taxonomic work to clarify the identity and phylogeny of the targeted species, ii) Contribute to an existing public DNA sequence database (e.g. NCBI), iii) Establish propagation initiatives to reduce pressure on the wild resource, and iv) Develop policy to accord the targeted species legal protection in Namibia and other range states. i) and ii) constitute the immediate Project objectives to which this CBD Bio-Bridge Initiative Small-Scale Funding contributes, through six key activities. All six activities were successfully implemented over the period March 2019 – March 2020, as detailed in the following report: 1. Outline in detail the activities implemented during the Project. Activity 1: Collection trip to northern Namibia – Herbarium voucher specimens of the targeted plants and leaf samples for molecular analysis will be collected from various sites in northern Namibia. Feedback: Herbarium plant specimens, leaf samples as well as soil samples were collected from 85 sites across nine Namibian regions in March – April 2019 (see Collection sites 2019 in “Report_BBI Namibia”).

  • Review on Gymnema: an Herbal Medicine for Diabetes Management
    REVIEW ON GYMNEMA: AN HERBAL MEDICINE FOR DIABETES MANAGEMENT Vaidya S.* Dr. H.S.Gaur University, Sagar (M.P.) Abstract Diabetes has been recognized by western medicine since the early 1800 s as being one of the most prevalent and controllable conditions affecting a large portion ofthe population. Gymnema Sylvestre, an Ayurvedic herb, came to be known as "destroyer of sugar" because, in ancient times, Ayurvedic physicians observed that chewing a few leaves of Gymnema sylvestre suppressed the taste of sugar. It is used today all over India for controlling blood sugar. Several bioactives has been isolated from that herb for diabetes cure. The present review elaborate the bioactives and some facts and mechanism which make this herb an effective remedy for the same. Introduction Gymnema Sylvestre is a woody, climbing plant of tropical forests of central and southern India and in parts of Africa. Distribution is worldwide and it is recognized in the traditional medicinal literature of many countries including Australia, Japan, and Vietnam. Gymnema has been referred to in some texts as Asclepias geminata, Gymnema melicida, and Periploca sylvestris. Gymnema has played an important role in Ayurvedic medicine for centuries. Its use has been confined primarily to the management of diabetes mellitus and similar hypo/hyperglycemic conditions. Despite the part used being the leaf, another common name of this species is miracle fruit,[1][2][3] which is shared by two other species: Synsepalum dulcificum and Thaumatococcus daniellii [1].
