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 ... -
Bioactive sesquiterpenoids from dicoma anomala subsp. gerrardii
(2008)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 ... -
Enantioselective synthesis of 1-substituted tetrahydroisoquinolines.
(2014)Many organic compounds are chiral and they are useful because of the biological activities associated with them. The biological activities of chiral compounds are often linked to absolute configuration, i.e. a compound ... -
Identification of triterpenoids in Brachylaena discolor DC, a plant with antidiabetic activity.
(2019)In recent times, metabolic diseases such as diabetes and hypertension have become a huge burden in populations around the world. Among these diseases, the number of diabetes mellitus cases have been increasing at an alarming ... -
Isolation and characterisation of secondary metabolites of two asteraceae species, Artemisia afra and Elytropappus rhinocerotis.
(2009)In this study two medicinal plant species, namely Artemisia afra Jacq. ex. Willd and Elytropappus rhinocerotis Less. (L.f) (= Dicerotamnus rhinocerotis Koekemoer), both belonging to the family Asteraceae, have been ... -
Isolation and characterization of cytotoxic compounds from Anthosperum hispidulum and Eriocephalus tenuifolius.
(2008)Cancer is a human tragedy that strikes and kills the lives of our beloved people. With a limited number of effective anticancer drugs from natural resources currently in use, there is a real need for new, safe, cheap and ... -
Isolation and identification of antidiabetic compounds from brachylaena discolor DC.
(2017)Abstract available in PDF file. -
Phytochemistry of Dais cotinifolia L.
(2018)Many plant-derived secondary metabolites have interesting biological activities and some plant compounds such as artemisinin (antimalarial) and vincristine (anticancer agent) are the active principles of main-stream ... -
South African plants as a source of herbicides : identification of a compound with phytotoxic activity from artemisia afra jacq. ex willd.
(2017)Abstract available in PDF file. -
Synthesis of prenylated benzoquinones.
(2010)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 ... -
Towards the total synthesis of a novel diarylheptanoid.
(2010)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 ...
