A simple entry into <strong>the</strong> series of tetracyclic heteroyohimbanes and secoyohimbane<br />
1994<br />
Liebigs Annalen Der Chemie<br />
(2): 151-158<br />
Abstract<br />
The divinylogous urethane 4a reacts in diluted acetic acid to give <strong>the</strong> indolochinolizine 9 (yield<br />
40%). The total amount grows up to 65%, if compound 14, prepared from 4a in nearly quantitative<br />
yield, is allowed to react with trifluoroacetic acid <strong>for</strong> a few minutes. Similarily, 4b and 4c give by<br />
treatment with SnCl2 and heat in an [4+2]-cycloaddition reaction <strong>the</strong> spiroindolines 17 and 18.<br />
Oxytryptamine reacts with 2 moles of 2 to give immediately <strong>the</strong> spirooxindole 21. This compound<br />
can be rearranged to give 23 (after treatment with acid, reduction and catalytic hydrogenation). 23<br />

Nutritional-value of edible fruits of indigenous wild trees in Malawi<br />
1994<br />
Forest Ecology and Management<br />
64(2-3): 245-248<br />
Abstract<br />
The edible portions of 16 edible wild fruits were analysed <strong>for</strong> moisture, protein, fat, crude fibre, ash<br />
and minerals (Ca, Mg, Fe, P, K, and Na). The total carbohydrate and energy contents were<br />
calculated. - Trichilia emetica, <strong>Strychnos</strong> spinosa, Azanza garckeana, Ximenia caffra and Parinari<br />
curatellifolia gave <strong>the</strong> highest levels of protein (17.0%), fat (31.2%), fibre (45.3%), ash (11.2%) and<br />
carbohydrate (88.2%), respectively. The highest and lowest energy values were found <strong>for</strong> <strong>Strychnos</strong><br />
spinosa (1923 kJ 100 g-1) and Azanza garckeana (810 kJ 100 g-1), respectively. Bauhinia thonningii<br />
af<strong>for</strong>ded <strong>the</strong> highest dry matter content (91.6%). - The highest contents of Ca, Mg, Fe, P, K and Na<br />
were found <strong>for</strong> Adansonia digitata (1156 mug g-1), Syzigium guineense (2247 mug g-1), Syzigium<br />
guineense (758 mug g-1), Trichilia emetica (3164 mug g-1), Ximenia caffra (41 79 1 mug g-1) and<br />
