“…). These secondary plant metabolites, which have no known function in the primary metabolic requirements of the plant species, increase the overall ability to survive and overcome environmental challenges (Harborne ). Plant extracts have proven for many years to be important sources of drugs and pesticides (Farnsworth et al .…”

Taraxacum officinale leaves are popular among Ghanaians as vegetable and/or beverage while extracts of Taraxacum officinale, Paulliniia pinnata and Thonningia sanguinea are present in common herbal remedies widely available without prescription in Ghana. This study was therefore aimed to identify possible interactions between these medicinal plant extracts and mitochondrial respiratory chain activity. The effects of these extracts on mitochondrial oxygen consumption were therefore investigated in situ using permeabilized mouse cardiac muscle fiber preparations and a substrate-inhibitor titration. The results showed that the ethanolic fraction of T. officinale leaves significantly increased the respiration rate in presence of rotenone and the state 3/state 2 ratio (respiratory control ratio) while the ethanolic extract of P. pinnata stem significantly decreased succinatestimulated respiration. The aqueous extract of T. sanguinea also significantly decreased respiration in presence of rotenone. PRACTICAL APPLICATIONSThe present study revealed that the extracts from Taraxacum officinale, Paulliniia pinnata and Thonningia sanguinea exhibited the potential to influence mitochondrial respiratory chain function. The result presented in this study provides evidence that T. officinale offers an opportunity to be explored as a natural energy booster. The decrease in succinate-stimulated respiration caused by the extract from P. pinnata provides further evidence for its use as a fish poison and strongly suggests that its use in herbal remedies may be detrimental. Furthermore, information about similar effects caused by traditional remedies would be useful not only in the discovery of novel therapeutic agents but also identification of extracts with the potential for long term toxicity. bs_bs_banner Journal of Food Biochemistry

“…The production of secondary metabolites results from complex interactions between biosynthesis, transport, stocking and degradation (Santos 1999). These processes, in turn, are governed by genes, being influenced by inheritance, physiological and climatic (temperature, seasonal effects, light intensity, day length) and edaphic factors (Santos 1999, Harborne 1977.…”

Ocimum selloi Benth, a native plant of Brazil, has medicinal uses as anti-diarrheic, antispasmodic and antiinflammatory product. The yield of essential oils of the inflorescences, containing flowers and seeds, was 0.6%, and the yield of leaves, collected in two different seasons, was 0.25% (June 2000) and 0.20% (January 2001), respectively. The essential oils of the inflorescences and leaves presented as major constituents trans-anethol (41.34%, 45.42%, 58.59%) and methyl chavicol (27.10%, 24.14%, 29.96%).

“…Very little is known of the accumulation of flavonoid sulfates in seagrass tissues and their functional roles remain unclear. Harborne (1977) suggested that conjugation with seagrass flavonoids might be a possible route for inactivation or storage of inorganic sulfate, and could have a dynamic function in salt uptake and metabolism. A sulfate conjugate is more water soluble than the unsulfated molecule or even the corresponding glycoside, thus facilitating transport to various cellular compartments and exudation in the water column.…”
