Bush Medicines Of Western Sydney, Hans Wohlmuth
Dr Hans Wohlmuth
The knowledge of traditional Aboriginal use of medicinal plants in the Sydney area is almost non-existent. A number of plants growing in Mitchell Park, northwest of Sydney, are discussed in terms of their potential medicinal use by the traditional owners of the area. In the absence of records of medicinal plant use in the area, the discussion draws upon information from other areas of Australia. Aboriginal health prior to European settlement is also briefly discussed in an attempt to identify some of the ailments Aboriginal people may have found themselves treating with bush medicines. It is concluded that the area …

What Are Aflatoxins?, Hans Wohlmuth
Dr Hans Wohlmuth
Aflatoxins are toxic secondary metabolites wh ich are rarely produced by species of mou Ids belonging to the genus Aspergillus. These moulds grow on stored plant foods, in particular peanuts, wheat and corn. In tropical countries an estimated 25% or more of the food may be contaminated with aflatoxins (Raven et al 1992).

Intraspecific Chemical Variability Of Essential Oil From Leaves Of Cupressus Atlantica Gaussen, An Endemic And Endangered Coniferous Species In Morocco, Abdelaziz Abbad, Youssef Sfairi, Hassani Lahcen, Khalid Bekkouche, Mohammed Markouk, Hans Wohlmuth, David Leach
Intraspecific Chemical Variability Of Essential Oil From Leaves Of Cupressus Atlantica Gaussen, An Endemic And Endangered Coniferous Species In Morocco, Abdelaziz Abbad, Youssef Sfairi, Hassani Lahcen, Khalid Bekkouche, Mohammed Markouk, Hans Wohlmuth, David Leach
Dr Hans Wohlmuth
The composition of essential oils isolated from leaves of 11 natural populations of Cupressus atlantica, an endemic and endangered coniferous species from Morocco, was investigated by GC-MS. In total, 42 essential oil components were identified, accounting for 73.1–97.7% of the total oil. Monoterpene (25.2–84.9%) and sesquiterpene hydrocarbons (12.2–46.8%) were the principal subclasses of compounds, with α-pinene (15–65.4%), germacrene D (5.9–30.5%), δ-3-carene (2–16.6%) and γ-cadinene (1.3–9.8%) as the main constituents. The results of the oil composition were analysed by hierarchical cluster and principal component analysis that established three main groups of essential oils. These oils were differentiated …
Osmophore Development In Stanhopea Anfracta And S. Pulla (Orchidaceae), Kenneth Curry
Osmophore Development In Stanhopea Anfracta And S. Pulla (Orchidaceae), Kenneth Curry
Kenneth J. Curry
The developmental anatomy and morphology of the floral scent glands (osmophores) were examined daily from the late bud stage to post-anthesis, for 2 species which are considered to be at opposite poles in the evolutionary development of the genus. The osmophore of S. anfracta was studied using morphometric techniques to estimate volume density of selected cellular inclusions, whereas the osmophore of S. pulla was examined qualitatively. The volume density of starch/amyloplast in S. anfracta remained relatively constant throughout most of the two-day flowering period as did the degree of cell vacuolation. The flower of S. pulla lasts only one day, …

Detection Of Panax Quinquefolius In Panax Ginseng Using ‘Subtracted Diversity Array’, Linhai Niu, Nitin Mantri, Chun Li, Charlie Xue, Hans Wohlmuth, Edwin Pang
Dr Hans Wohlmuth
BACKGROUND: Food adulteration remains a major global concern. DNA fingerprinting has several advantages over chemical and morphological identification techniques. DNA microarray-based fingerprinting techniques have not been used previously to detect adulteration involving dried commercial samples of closely related species. Here we report amplification of low-level DNA obtained from dried commercial ginseng samples using the Qiagen™ REPLI-g® Kit. Further, we used a subtracted diversity array (SDA) to fingerprint the two ginseng species, Panax ginseng and Panax quinquefolius, that are frequently mixed for adulteration. RESULTS: The two ginseng species were successfully discriminated using SDA. Further, SDA was sensitive enough to detect a …

Diarylheptanoid From Pleuranthodium Racemigerum With In Vitro Prostaglandin E2 Inhibitory And Cytotoxic Activity, Hans Wohlmuth, Myrna Deseo, Don Brushett, Dion Thompson, Graham Macfarlane, Lesley Stevenson, David Leach
Diarylheptanoid From Pleuranthodium Racemigerum With In Vitro Prostaglandin E2 Inhibitory And Cytotoxic Activity, Hans Wohlmuth, Myrna Deseo, Don Brushett, Dion Thompson, Graham Macfarlane, Lesley Stevenson, David Leach
Dr Hans Wohlmuth
Bioactivity-guided fractionation of an ethanolic extract of the rhizome of Pleuranthodium racemigerum, a tropical Zingiberaceae species from North-eastern Australia, resulted in the isolation and structural elucidation of 1-(4″-methoxyphenyl)-7-(4′-hydroxyphenyl)-(E)-hept-2-ene (1), a new diarylheptanoid related to curcumin. Compound 1 was a fairly potent inhibitor of prostaglandin E2 production in 3T3 murine fibroblasts (IC50 ≈ 34 μM) and also displayed moderate cytotoxicity against this cell line (IC50 = 52.8 μM). The compound also demonstrated cytotoxic activity against the P388D1 murine lymphoblast cell line (IC50 = 117.0 μM) and four human cell lines: Caco-2 colonic adenocarcinoma (IC50 = 44.8 μM), PC3 prostate adenocarcinoma (IC50 …

Increasing Long Term Soil Carbon Sequestration In Agriculture And Forestry, Leigh Sullivan, Jeffrey Parr
Increasing Long Term Soil Carbon Sequestration In Agriculture And Forestry, Leigh Sullivan, Jeffrey Parr
Jeffrey Parr
Terrestrial carbon sequestration is fundamental to the global carbon cycle and is being utilised to counter increases in anthropogenic carbon dioxide emissions. Although soil organic carbon dominates the terrestrial carbon cycle in terms of total quantity, the long term sequestration of soil organic carbon in the Holocene was relatively low (<1 % of net primary production). Consequently there is a viewpoint that soil has a low carbon storage potential and hence only a relatively minor role to play in countering anthropogenic carbon dioxide emissions. Long term (decades to millennia) soil organic carbon sequestration mechanisms are currently thought to be mainly due to the physical protection of chemically recalcitrant organic matter within clays. Recent research is presented here to show that some forms of soil organic carbon (e.g. that occluded in phytoliths) are not readily physically accessible to the agents responsible for decomposition and that these forms also play a major role in long term soil organic carbon sequestration. Phytoliths (literally ‘plant rocks') are silicified features that form as a result of biomineralization within plants. The occlusion of carbon within phytoliths has been recently found to be an important process in the long-term sequestration of terrestrial carbon (Parr & Sullivan, 2005). Moreover, relative to the other soil organic carbon constituents, the carbon occluded in phytoliths (PhytOC) is highly resistant against decomposition. Although comprising < 10 % of the total carbon pool in contemporary topsoils (with ages of < 200 years), the resistance of this carbon fraction against decomposition processes resulted in this carbon fraction comprising 70 % of the total carbon pool in the buried topsoils after decomposition for 3,000 years in soils under grasslands. The carbon in phytoliths is sequestered over the geological time scale rather than the anthropological. Experimental and modelled data presented here indicates that the long term carbon sequestration potential of soil can be increased considerably in areas under managed vegetation (e.g. crops) by the adoption of simple agronomic and silvicultural practices.
Carbon Bio-Sequestration Within The Phytoliths Of Economic Bamboo Species, Jeffrey Parr, Leigh Sullivan, Bihua Chen, Gongfu Ye, Zheng Wiepeng
Carbon Bio-Sequestration Within The Phytoliths Of Economic Bamboo Species, Jeffrey Parr, Leigh Sullivan, Bihua Chen, Gongfu Ye, Zheng Wiepeng
Jeffrey Parr
The rates of carbon bio-sequestration within silica phytoliths of the leaf litter of 10 economically important bamboo species indicates that (a) there is considerable variation in the content of carbon occluded within the phytoliths (PhytOC) of the leaves between different bamboo species, (b) this variation does not appear to be directly related to the quantity of silica in the plant but rather the efficiency of carbon encapsulation by the silica. The PhytOC content of the species under the experimental conditions ranged from 1.6% to 4% of the leaf silica weight. The potential phytolith carbon bio-sequestration rates in the leaf-litter component …
