Phytochemical and anti-drepanocytosis studies of Cajanus cajan, Callistemon viminalis, Melaleuca bracteata var. Revolution Gold and Syzygium guineense.
All over Africa, traditional healers use medicinal plants to prepare medicines to treat a wide range of illnesses. One of these illnesses is sickle cell anaemia or drepanocytosis or sicklemia. This disease is particularly ...
Structure and synthesis of Phloroglucinol derivatives from Hypericum roeperianum
The research presented in this study combines natural product chemistry with organic
Bioactive sesquiterpenoids from dicoma anomala subsp. gerrardii
Through South Africa’s first collaborative project between a large scientific organisation, the Council for Scientific and Indust rial Research (CSIR), and the Traditional Healer’s Committee, Dicoma anomala was identified ...
Towards the total synthesis of a novel diarylheptanoid.
Diarylheptanoids are a family of plant metabolites with a characteristic structure of two hydroxylated aromatic rings attached by a linear seven-carbon chain. Diarylheptanoids have mostly been isolated from plants belonging ...
Antidiabetic compounds from Hypoxis colchicifolia and Terminalia sericea.
In this project two medicinal plant species, namely Hypoxis colchicifolia Bak (Hypoxidaceae) and Terminalia sericea Burch. (Combretaceae), have been investigated and different compounds isolated and characterised. The aim ...
Synthesis of prenylated benzoquinones.
The research presented in this study demonstrates the critical role that organic synthesis plays in natural product chemistry. The biological activity demonstrated by 2-methyl-6-(3-methyl-2- butenyl)benzo-1,4-quinone ...
The chemical investigation of Ledebouria zebrina and Scilla natalensis.
Ledebouria zebrina and Scilla natalensis Planch were the two species investigated in this work. Ledebouria zebrina belongs to the Hyacinthaceae (Liliacea sensu lato) and to this date, the chemical composition of this ...
Extractives from eucomis montana and agapanthus inapertus.
Two species belonging to different families were investigated, Eucomis montana from the Hyacinthaceae and Agapanthus inapertus from the Agapanthaceae. To date no previous chemical investigation on Eucomis montana has ...
Extractives from the Hyacinthaceae.
Four species belonging to the Hyacinthaceae family were investigated. The taxonomy of the Hyacinthaceae is currently under review and therefore compounds isolated from these plants could provide valuable chemical evidence ...
Homoisoflavonids and stilbenoids from Scilla species.
Bulbs of Scilla natalensis Planch, Scilla nervosa (Burch.) Jessop, Scilla dracomontana Hilliard and Burt and Scilla kraussii Bak. (Hyacinthaceae) were investigated. The plants are widely used by the local African people ...
