Cytotoxic and antioxidant flemingins g-p from the leaves of flemingia grahamiana
(University of Nairobi, 2014)
The known flemingins A-C (1-3) and nine new chalcones, named flemingins G-O (4-12), along with deoxyhomoflemingin (13) and emodin (14) were isolated from a leaf extract of Flemingia grahamiana. The isolated chalcones were ...
Additional Cooking Fuel Supply And Reduced Global Warming Potential From Recycling Charcoal Dust Into Charcoal Briquette In Kenya
(University of Nairobi, 2014-06)
Rising demand for energy is one of the major challenges facing the world today and charcoal is a principal fuel in Kenya. Faced with energy poverty many poor households turn to briquette making. This study assessed the ...
