The author hereby declares that the research presented here is his own original work and has not been submitted to any other institution for the award of a degree. Douglas I. King 4th August 2017 ii Dedication I dedicate this thesis to my fiancée and future wife: My sweet girl, Anna Sanders Robinson Every day with you, my dearest, is a pleasure; you have always brought full support, comfort and love to me in all my endeavours. I trust I have provided you with the full support, comfort and love you so richly deserve in turn. I rejoice that I will soon be able to give you the time and attention I have had to divert to my research: these have been occasionally trying times for us both. I met you, asked you out, became your boyfriend, moved in and proposed to you all during the length of my candidature – it’s been an exciting and adventurous four years. Know that whatever adventures life brings us in the future, my sweet girl, I will always love you as you love me. iii Acknowledgements First and foremost, words cannot express my deep and lasting gratitude to my supervisor, A/Prof Colin Duke. I have had the extreme honour to have had Colin supervise both my Honours and Doctoral studies: a more helpful, available, interested and (above all) forgiving supervisor is not to be found. His natural products knowledge is immense; I have been lucky indeed to learn what little I could from him. As he approaches retirement from academia (but never research), I wish him continuing success with Australian propolis and look forward to a long collaboration. I am most grateful to Dr Rujee Duke and Dr Van Tran, whom I have also had the privilege to work closely with. Rujee’s knowledge of pharmacology and cell biology is encyclopaedic; I am extremely appreciative for her advice in these areas, where I have always struggled. Van, also a past supervisor of my Honours work, has always maintained an interest in my research and has made several helpful comments over the years. Dr Bret Church, roped in at last minute as my auxiliary supervisor, has kept a close eye on my progress and given much insight into the politics of academia – I thank him for both. I heartily thank those students I’ve shared the lab with, particularly my fellow researchers in the Duke Group: Dr Noushin Aminimoghadamfarouj and Dr Kaiser Hamid. Our collaboration has always been tight, and I’d like to think we’ve all provided useful tips and tricks to one another. Certainly, I’ve been the recipient of many. I’d also like to thank Noushin’s husband, Dr Reza Nematollahi, not strictly from our lab, but always present and a scholar and a gentleman. I had the honour of being the guest of Noushin and Reza for their graduation as Doctors (Sydney, 2016); I thank them for this mark of friendship and wish them both long and productive careers. For our shared work on genus Lepidosperma, I am grateful to our botanist and taxonomist collaborators Dr Russell Barrett (University of Western Australia), Karen Wilson (Royal Botanic Garden, Sydney), Prof Jeremy Bruhl and George Plunkett (University of New England). I particularly thank George; his doctoral research on chemotaxonomy of sedges has helped mine and my doctoral research, I trust, has helped his. I thank Dr Nick Proschogo of the School of Chemistry Mass Spectrometry Facility for performing mass spectrometry on DK-2, DK-3 and other samples at very short notice, and to Eurofins Panlabs for the performance of the cellular assays on DK-1. Turning from academe, I thank most deeply the love and support shown to me by my mother, Joanne King, and father, Mark King. Mum, Dad, a man could have no finer parents: know I love you dearly and know this thesis will make you proud – not that you weren’t already. I also thank my grandmother, Dawn King, for her love, support and ongoing interest in my studies. My siblings, Alison King and Dr Malcolm King (Melb, 2017), have always been supportive and I thank them deeply. I especially thank Mal, who submitted his thesis at The University of Melbourne last year (1), for being, in many ways, the ‘scouting party’ as to what I should iv expect over the course of my studies. I can only hope my thesis is half as robust and scholarly as his was. I also thank Mal and Ally for the gifts of a Mini Express One stovetop coffee maker (Bialetti Industrie Spa, Brescia, Lombardy, Italy) and a džezva for making Serbian coffee; both have both proved extremely useful in these last few thesis-writing months. I’d also like to treasure the memory of my good mate and loyal companion: my dog, Syd (2000-2016). He was a good boy to the very end and is sorely missed by the whole family. In the extracurricular world of Sydney University, I like to thank all my colleagues and friends at the Sydney University Postgraduate Representative Association, where I had the honour of being Treasurer for two years; and the Sydney University Musical and Madrigal Societies. It’s been a real pleasure and escape from the lab to sing with fellow students. I’d also like to thank the Faculty of Pharmacy postgraduate coordinator, Prof Dai Hibbs, who has always been good for a chat and a joke with this very Saesneg Australian. I thank all my fellow staff and the patients of Helensburgh Pharmacy, who are always curious as to my studies and take some pride in their ‘Dr’ Doug. It’s a wonderful town and place to work in. An especial thanks to the fellow members of the Society for Classic Pubs: Scott Ferguson, Tony Perusco, Alex Rae, and Dr Cass Stuart (Sydney, 2016) (2). This thesis hasn’t been quite an ‘open misère’, but regular meetings of the SCP have certainly eased it along. Good friends, good beer, good times. And, of course and always, all my gratitude and love to my dearest sweet girl, Anna. v Contents Declaration................................................................................................................................ ii Dedication ................................................................................................................................ iii Acknowledgements ................................................................................................................. iv Contents ................................................................................................................................... vi List of figures ........................................................................................................................... xi List of tables........................................................................................................................... xiv List of abbreviations ............................................................................................................ xvii Publications and conferences ................................................................................................ xx Abstract .................................................................................................................................. xxi Chapter One: A Review of Propolis Literature ............................................................................................. 1 1.1 General introduction and history ......................................................................................... 2 1.2 Physical nature of propolis................................................................................................... 7 1.3 Collection, manufacture and use of propolis by bees .......................................................... 8 1.4 Chemical variability of propolis ........................................................................................ 11 1.4.1 Early research...................................................................................................... 11 1.4.2 Major propolis types ........................................................................................... 12 1.4.2.1 Temperate propolis .............................................................................. 13 1.4.2.2 Mediterranean propolis ........................................................................ 15 1.4.2.3 Tropical propolis .................................................................................. 16 1.4.2.4 Pacific propolis..................................................................................... 17 1.4.3 Australian propolis .............................................................................................. 18 1.4.4 Kangaroo Island propolis .................................................................................... 19 1.5 Biological activity and medicinal use of propolis.............................................................. 23 1.5.1 Antimicrobial and antiparasitic activity .............................................................. 23 1.5.2 Antioxidant activity ............................................................................................ 26 1.5.3 Anti-inflammatory and immunomodulatory activity .........................................

April-June 2017. doi: 10.1590/0102-33062016abb0409 Floristic and ecological characterization of habitat types on an inselberg in Minas Gerais, southeastern Brazil Luiza F. A. de Paula1*, Nara F. O. Mota2, Pedro L. Viana2 and João R. Stehmann3 Received: November 21, 2016 Accepted: March 2, 2017 . ABSTRACT Inselbergs are granitic or gneissic rock outcrops, distributed mainly in tropical and subtropical regions. Th ey are considered terrestrial islands because of their strong spatial and ecological isolation, thus harboring a set of distinct plant communities that diff er from the surrounding matrix. In Brazil, inselbergs scattered in the Atlantic Forest contain unusually high levels of plant species richness and endemism. Th is study aimed to inventory species of vascular plants and to describe the main habitat types found on an inselberg located in the state of Minas Gerais, in southeastern Brazil. A total of 89 species of vascular plants were recorded (belonging to 37 families), of which six were new to science. Th e richest family was Bromeliaceae (10 spp.), followed by Cyperaceae (seven spp.), Orchidaceae and Poaceae (six spp. each). Life forms were distributed in diff erent proportions between habitats, which suggested distinct microenvironments on the inselberg. In general, habitats under similar environmental stress shared common species and life-form proportions. We argue that fl oristic inventories are still necessary for the development of conservation strategies and management of the unique vegetation on inselbergs in Brazil. Keywords: endemism, granitic and gneissic rock outcrops, life forms, terrestrial islands, vascular plants occurring on rock outcrops within the Atlantic Forest Introduction domain, 416 are endemic to these formations (Stehmann et al.

    Acta bot. bras. 21(2): 325-333. 2007 Pollination of two species of Vellozia (Velloziaceae) from high-altitude quartzitic grasslands, Brazil Claudia Maria Jacobi1,3 and Mário César Laboissiérè del Sarto2 Received: May 12, 2006. Accepted: October 2, 2006 RESUMO – (Polinização de duas espécies de Vellozia (Velloziaceae) de campos quartzíticos de altitude, Brasil). Foram pesquisados os polinizadores e o sistema reprodutivo de duas espécies de Vellozia (Velloziaceae) de campos rupestres quartzíticos do sudeste do Brasil. Vellozia leptopetala é arborescente e cresce exclusivamente sobre afloramentos rochosos, V. epidendroides é de porte herbáceo e espalha- se sobre solo pedregoso. Ambas têm flores hermafroditas e solitárias, e floradas curtas em massa. Avaliou-se o nível de auto-compatibilidade e a necessidade de polinizadores, em 50 plantas de cada espécie e 20-60 flores por tratamento: polinização manual cruzada e autopolinização, polinização espontânea, agamospermia e controle. O comportamento dos visitantes florais nas flores e nas plantas foi registrado. As espécies são auto-incompatíveis, mas produzem poucas sementes autogâmicas. A razão pólen-óvulo sugere xenogamia facultativa em ambas. Foram visitadas principalmente por abelhas, das quais as mais importantes polinizadoras foram duas cortadeiras (Megachile spp.). Vellozia leptopetala também foi polinizada por uma espécie de beija-flor territorial. A produção de sementes em frutos de polinização cruzada sugere que limitação por pólen é a causa principal da baixa produção natural de sementes. Isto foi atribuído ao efeito combinado de cinco mecanismos: autopolinização prévia à antese, elevada geitonogamia resultante de arranjo floral, número reduzido de visitas por flor pelo mesmo motivo, pilhagem de pólen por diversas espécies de insetos e, em V.

KEYWORDS : Pseudarthria viscida, New (Fabaceae) from Andaman Islands in the Bay of generic record, Andaman Islands Bengal Jawaharlal Nehru Tropical Botanic Garden and Research Institute, Thiruvananthapuram Sam P. Mathew 695 562, Kerala, India. ABSTRACT Andaman-Nicobar Archipelago, the insular habitat in the Bay of Bengal is highly affluent with plant diversity. Nevertheless, evergreen insular rainforests are mostly devoid of herbaceous components. The compact canopy of the evergreen type vegetation rigorously restricts sunlight to ground level creating strict competition among the herbaceous species for space with enough sun light. Therefore, several herbaceous elements are confined their occurrence to isolated ideal micro ecological niches. Pseudar- thria viscida (L.) Wight & Arn. is a newly recorded herbaceous evergreen forest component from the Baratang Island in Middle Andaman group.
