Germination studies on seed of fruit-trees indigenous to Malawi<br />
1994<br />
Forest Ecology and Management<br />
64(2-3): 111-125<br />
Abstract<br />
Indigenous fruit trees play an important role in rural areas in Malawi. However, in<strong>for</strong>mation on<br />
propagation techniques <strong>for</strong> <strong>the</strong>se species is scantily available. Freshly obtained seed of 16<br />
indigenous fruit trees and one exotic species were <strong>the</strong>re<strong>for</strong>e collected and tested <strong>for</strong> germination<br />
after applying eight different seed pretreatments. The pretreatments included direct sowing, washing,<br />
soaking, hot water treatment and different degrees of removal of <strong>the</strong> seedcoat. The objective was to<br />
find a simple technique to germinate seed of each species so that such a technique can be applied<br />
under village conditions in Malawi. - More than 80% germination was achieved <strong>for</strong> Bridelia<br />
cathartica, Bridelia micrantha, Diospyros mespili<strong>for</strong>mis, Parkia filicoidea, Piliostigma thonningii,<br />
<strong>Strychnos</strong> spinosa, Syzygium cordatum, Tamarindus indica, Uapaca kirkiana, Ziziphus abyssinica<br />
and Ziziphus mauritiana by simply cleaning and soaking <strong>the</strong> seeds. Quicker germination could be<br />
achieved by partial removal of <strong>the</strong> seedcoat <strong>for</strong> some species. Azanza garckeana and Parinari<br />
curatellifolia, however, required partial or complete removal of <strong>the</strong> seedcoat to achieve some<br />
germination. Flacourtia indica and Parinari curatellifolia had very poor germination of 20% and<br />
1 7 % , r e s p e c t i v e l y .<br />

2,7-dihydroxyapogeissoschizine from root bark of <strong>Strychnos</strong> gossweileri<br />
1994<br />
Phytochemistry<br />
35(2): 533-536<br />
Abstract<br />
In this paper, we describe <strong>the</strong> isolation and structural determination of 2,7-<br />
dihydroxyapogeissoschizine, a new alkaloid from <strong>the</strong> root bark of <strong>Strychnos</strong> gossweileri. Elucidation<br />
of its structure is based mainly on 1D and 2D NMR studies; its con<strong>for</strong>mation was optimized by<br />
energy minimization. According to a preliminary test, this substance shows low toxicity to B16<br />
melanoma cells, but not <strong>for</strong> non-cancer 3T3 fibroblasts cultured in vitro.
