Abstract:

Abstract The bark of Pausinystalia yohimbe [K. Schumann] Pierre (Rubiaceae), long valued as an aphrodisiac in West Africa, recently has been promoted in the United States as a dietary supplement alternative to anabolic steroids for enhancement of athletic performance. As the number of yohimbe products on the retail market increases, concerns about their safety are raised because of the reported toxicity of yohimbine (the major alkaloid of the plant). Although plant materials are usually identified microscopically, we were unable to identify them in many of the products, because as their labels indicated, the products were mixtures of various bo-tanicals or were bark extracts and contained little or no plant material. A method for extraction and capillary gas chromatographic (GC) separation of the alkaloids of P. yohimbe was, therefore, developed and used to analyze a number of commercial yohimbe products. The method involved solvent extraction and partitioning in chloroform–water followed by separation on a methyl silicone capillary GC column (N–P detection). Comparisons of chromatograms of extracts of authentic bark with those of commercial products indicated that, although many products contained measurable quantities of the alkaloid yohimbine, they were largely devoid of the other alkaloids previously reported in this species. Concentrations of yohimbine in the commercial products ranged from &lt;0.1 to 489 ppm, compared with 7089 ppm in the authentic material. Authentic bark has been reported to contain up to 6% total alkaloids, 10–15% of which are yohimbine. The possible presence of undeclared diluents in the products was indicated by peaks in product chromatograms but not in those of authentic bark.

Abstract:

Mestrado em Viticultura e Enologia - Instituto Superior de Agronomia / Faculdade de Ciências. Universidade do Porto<br>The offer of different wine brands is increasing in our society. The investigation and search for new profiles aromatic-gustatory try to differentiate the product in a broad market, generic and not very varied. The launch of new wines is distinguished by its terroir, marketing or combinations of existing types of wine as Verde Rosé and Porto Rosé. Another phenomenon has been the growing interest for functional foods and, more particularly, for functional wines. In this field, even though there are very few studies, it is common to associate beneficial capacities, as wine polyphenols on human health. The wine contact with the wood, especially oak, either in barrels or more recently, as wood chips, might improve even more this positive benefits, especially if we deal with white wines. It‟s also known that consumption of wine is related to pleasure, satisfaction, people status, and by consequence, an important cultural issue. It‟s common sense that drinking wine uninhibited people, affecting them mentally and physically. In a moderated level, wine consumption can lead consumers to sexual approach. At this level, there‟s a known and natural product described as aphrodisiac, even though is not scientifically proved: Pausinystalia yohimbe, or „Pau-de-cabinda‟, its popular name. In its bark we can find a major alkaloid called Yohimbine, used as medicine, or as a traditional way to prevent heart diseases and male sexual impotence (Tchoundjey et al., 2001). This work focuses on a wine vinified with Pausinystalia yohimbe, and it will demonstrate that this product stays a wine without losing its main phenolic compounds. At the same time, it will be showed the potential business opportunities in producing a wine with this profile. The market research about this product shows us that there‟s a new market segment, especially between 30 to 44 years old. Our target consumer isn‟t only an ordinary consumer, but someone with different consumption needs and wishes. It is a person searching everyday for more information about the product is buying, trying to find new sensations and searching for different opportunities in wine consumption. This work is based on this premise, bringing out a new wine with an extra plus to the consumer and not just a mix of existing tastes and concepts.

Abstract:

Botanical medicines can play an important role in helping men and women with sexual dysfunction. Marketing hype has distorted their role, and illegal adulteration of herbal products with unlabeled phosphodiesterase type 5-inhibiting drugs is a rampant problem in the marketplace. Research most validates the traditional use of Panax ginseng (Asian ginseng) root, Pausinystalia yohimbe (yohimbe) bark, Epimedium spp (horny goat weed) leaf and stem, and Crocus sativus (saffron) stamen for enhancing libido and erectile function. Withania somnifera (ashwagandha) root, Turnera diffusa (damiana) leaf, and Tribulus terrestris (caltrop vine) fruit are less well studied but still have a strong reputation in traditional medicine as aphrodisiacs. Clinical use of these herbs is discussed with case examples. The problem with biopiracy of traditional aphrodisiacs from the Global South is also reviewed.
