Author Title Year Source title Reference Chen, W. S., L. L. Liu, X. Li, L. W. Li, S. G. Ji, G. Q. Zhang and Y. F. Chai Separation and determination of strychnine and brucine in Strychnos nux vomica 2000 Biomedical Chromatography 14(8): 541-543 Abstract A capillary zone electrophoresis method was developed for the separation and determination of strychnine and brucine in Strychnos nux-vomica L. and its preparation. The factors that could affect the separation were studied, such as the types and concentrations of electrolytes, pH, ionic strength and organic modifier. The optimum running buffer was 20 mmol/L of ammonium acetate containing 0.2 mol/L of glacial acetic acid (pH 3.64). The applied voltage was 25 kV and the wavelength of the UV detector was set at 214 nm. The established method with dopamine hydrochloride as internal standard was linear in the range of 5-100 mug/mL for both strychnine and brucine. The recovery was 102.96% for strychnine and 98.56% for brucine. The extracts of Strychnos nux-vomica and its preparation could be directly injected for analysis.

Synthesis of tetrahydrocarbazo 2000 Journal of Heterocyclic Chemistry 37(1): 11-14 Abstract The synthesis of new precursors 8 and 15 for the synthesis of tetracyclic indole alkaloids were described. Many new intermediates 4-7 and 9-14 have also been synthesized. Author Title Year Source title Reference Abstract Frederich, M., M. C. De Pauw, G. Liabres, M. Tits, M. P. Hayette, V. Brandt, J.

Author Title Year Source title Reference Liu XX; Wang T; Xu QG; Ma CR; Cook JM Enantiospecific total synthesis of the enantiomer of the indole alkaloid affinisine 2000 Tetrahedron Letters 41(33): 6299-6303 Abstract The enantiomer of affinisine has been synthesized (from L-tryptophan) with 100% diastereoselectivity via the asymmetric Pictet-Spengler reaction coupled with a Pd-0 (enolate mediated) coupling process. This enantiomer has also been converted into a key intermediate which provides a route to the enantiomers of both macroline and alstonerine following the previous work of LeQuesne.

Grivetti Food-related behaviors during drought: A study of rural Fulani, northeastern Nige 2000 International Journal of Food Sciences and Nutrition 51(2): 91-107 Abstract Two rural settled Fulani villages in northeast Nigeria were surveyed for dietary practices and use of edible wild plants (n = 100 adult subjects). Dietary patterns and medical data were obtained for children under 5, pregnant and lactating women and the elderly. A diversified diet was maintained at both geographical locations through hunting, gathering, agriculture, horticulture, animal husbandry, food exchanges and cash purchases. Edible wild plants associated with children included fruits of baure (Ficus sycomorus), faru (Lannea schiniperi), giginya (Gardenia aqualla), kokiya (Strychnos spinosa) and nunu (Parinari curatellitolia). Leaves of shiwaka (Veronia colorate) were consumed by lactating women to stimulate breastmilk production. Generally, fruits of baure (Ficus sycomorus) were eaten to counter stomach pain; fruits of kisni (Bridelia ferruginea) were eaten to treat diarrhea; and bark of kuka (Adansonia digitata) was consumed for weight gain. Food storage was more important during wet seasons than dry because of local and regional flooding. Adult Fulani men rode to distant markets on bicycles, while women walked to market and in some instances expended 3200 k c a l / d a y e n g a g i n g i n t h i s a c t i v i t y .
