Scientific Assessment of Ephedra Species (Ephedra Spp.)
Annex 3 Ref. Ares(2010)892815 – 02/12/2010 Recognising risks – Protecting Health Federal Institute for Risk Assessment Annex 2 to 5-3539-02-5591315 Scientific assessment of Ephedra species (Ephedra spp.) Purpose of assessment The Federal Office of Consumer Protection and Food Safety (BVL), in collaboration with the ALS working party on dietary foods, nutrition and classification issues, has compiled a hit list of 10 substances, the consumption of which may pose a health risk. These plants, which include Ephedra species (Ephedra L.) and preparations made from them, contain substances with a strong pharmacological and/or psychoactive effect. The Federal Ministry of Food, Agriculture and Consumer Protection has already asked the EU Commission to start the procedure under Article 8 of Regulation (EC) No 1925/2006 for these plants and preparations, for the purpose of including them in one of the three lists in Annex III. The assessment applies to ephedra alkaloid-containing ephedra haulm. The risk assessment of the plants was carried out on the basis of the Guidance on Safety Assessment of botanicals and botanical preparations intended for use as ingredients in food supplements published by the EFSA1 and the BfR guidelines on health assessments2. Result We know that ingestion of ephedra alkaloid-containing Ephedra haulm represents a risk from medicinal use in the USA and from the fact that it has now been banned as a food supplement in the USA. Serious unwanted and sometimes life-threatening side effects are associated with the ingestion of food supplements containing ephedra alkaloids. Due to the risks described, we would recommend that ephedra alkaloid-containing Ephedra haulm be classified in List A of Annex III to Regulation (EC) No 1925/2006. -

Antioxidant and Acetylcholinesterase-Inhibitory Properties of Long-Term Stored Medicinal Plants Stephen O Amoo, Adeyemi O Aremu, Mack Moyo and Johannes Van Staden*
Amoo et al. BMC Complementary and Alternative Medicine 2012, 12:87 http://www.biomedcentral.com/1472-6882/12/87 RESEARCH ARTICLE Open Access Antioxidant and acetylcholinesterase-inhibitory properties of long-term stored medicinal plants Stephen O Amoo, Adeyemi O Aremu, Mack Moyo and Johannes Van Staden* Abstract Background: Medicinal plants are possible sources for future novel antioxidant compounds in food and pharmaceutical formulations. Recent attention on medicinal plants emanates from their long historical utilisation in folk medicine as well as their prophylactic properties. However, there is a dearth of scientific data on the efficacy and stability of the bioactive chemical constituents in medicinal plants after prolonged storage. This is a frequent problem in African Traditional Medicine. Methods: The phytochemical, antioxidant and acetylcholinesterase-inhibitory properties of 21 medicinal plants were evaluated after long-term storage of 12 or 16 years using standard in vitro methods in comparison to freshly harvested materials. Results: The total phenolic content of Artemisia afra, Clausena anisata, Cussonia spicata, Leonotis intermedia and Spirostachys africana were significantly higher in stored compared to fresh materials. The flavonoid content were also significantly higher in stored A. afra, C. anisata, C. spicata, L. intermedia, Olea europea and Tetradenia riparia materials. With the exception of Ekebergia capensis and L. intermedia, there were no significant differences between the antioxidant activities of stored and fresh plant materials as measured in the β-carotene-linoleic acid model system. Similarly, the EC50 values based on the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay were generally lower for stored than fresh material. Percentage inhibition of acetylcholinesterase was generally similar for both stored and fresh plant material. -

Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny. -
