Temperature Tanzania

The plants used for this study were collected primarily based on information provided by medicine men in East Africa, mainly in Kenya and Tanzania (3). Botanically identified plants were extracted with methanol at ambient temperatures. The extracts were first tested for their antimicrobial activity against four representative microorganisms at 100 fig/ml (4). The active extracts were then tested against more microorganisms. As a result, interestingly, the information gathered from medicine... 

The chemical profile of New Kawogo root latex, which is also presented in Figure 3, contained peaks for 1, 2 and 4 but also contained 3, tentatively identified as octadecyl caffeate. This compound appears to be present at much lower concentrations in the variety Tanzania. Compounds 1 and 3 have not previously been found in sweet potato and so are reported here for the first time. When the synthetic compound 2 (100% E-form) was left in solution for 3 days at room temperature a second compound appeared, eluting approximately 30 seconds earlier and with a similar mass spectrum and a UV spectrum consistent with the Z-form of coumaric acid. Thus it is presently proposed that the peak eluting in fi ont of 4 in Figure 3 is the Z-form of 4 since this peak has an identical MS to 4 and a UV spectrum consistent with the Z-form of octadecyl /7-coumarate.

Gorter (1910) observed the formation of lactic acid in the fermentation of a Liberia coffee. The acid was identified by Schormuller et al. (1961) in a commercial coffee extract (0.45%, 9% of the acid content), and the presence confirmed by Woodman et al. (1968). Feldman et al. (1969) mentioned a content of 0.055-0.09% based on the dry coffee basis, for medium to dark roast arabica and robusta coffees. Blanc (1979) considered that the content of this acid, low in green beans (0.08-0.09% of the dry material), only slowly increased to 0.10-0.16% during roasting for Tanzania and Kenya arabicas. Van der Stegen and van Duijn (1988) could measure the content of lactic acid only in roasted coffee (0.0-0.18%d.m.) with an increase if a brew was maintained at high temperature. Maier (1987) similarly... 

The hottest place in Southern African Development Community (SADC) identi-tied so far is Dar es Salaam Group Aw) in Tanzania (see Fig. 4.13). Mean maximum temperatures increase to 31.6°C in February, and never decrease below 21°C. The most appropriate temperature for long-term stability testing of medicinal products to be marketed in Tanzania and SADC is 30°C. That value includes a safety margin of 13% added to the highest MKT calculated for Dar es Salaam.
