Dr Claudia Ntsapi
Dr Matlakala C Ntsapi is a Senior Lecturer and researcher in the Department of Basic Medical Sciences at the UFS.

A researcher from the University of the Free State (UFS) is investigating the potential benefits of medicinal plants as supplementary treatments for neurodegenerative diseases such as Alzheimer’s, Parkinson’s and Huntington’s diseases.

The work of Dr Matlakala Claudia Ntsapi, Senior Lecturer in the Department of Basic Medical Sciences at the UFS, focuses on preserving human brain health to delay or prevent age-related conditions.

According to her, while the primary focus is on age-related neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and Huntington’s, the bioactive compounds in these medicinal plants may also have therapeutic potential for other neurological disorders, various types of cancers and Type 2 Diabetes. The broad protective effects of these plant-based bioactive compounds could make them relevant in the potential treatment of other diseases involving oxidative stress and inflammation.

She is involved in several multidisciplinary projects, collaborating with research experts from Denmark, the UK, and various national institutions such as the Central University of Technology (CUT), North West University (NWU), and the Stellenbosch University (SUN), as well as colleagues from the UFS. 

The potential of medicinal plants

“In collaboration with experts from our institution, the CUT and SU, who have strong backgrounds in pharmacology and ethnobotany, we are focusing on underexplored medicinal plants and nutraceuticals. These plants contain bioactive compounds with potential neuroprotective properties, which are believed to provide extra health benefits beyond basic nutritional value,” says Dr Ntsapi.

“We hope that these medicinal plants have the potential to preserve cognitive function and slow the progression of neurodegenerative diseases like Alzheimer’s. Specifically, we aim to identify novel therapeutic targets and discover new avenues for intervention that can improve the quality of life for individuals affected by age-related brain conditions,” she says.

Identifying therapeutic targets and discovering new interventions

The bioactive compounds found in selective medicinal plants and nutraceuticals, explains Dr Ntsapi, serve as a promising source of ‘natural’ therapeutics that may be safer and have fewer side effects compared to conventional synthetic drugs. Additionally, the untapped potential of these compounds for neuroprotection and the preservation of brain health could provide innovative therapeutic solutions. These compounds may be used as complementary therapies to existing drugs, which often have limited efficacy on their own, thereby enhancing overall treatment outcomes for neurodegenerative diseases.

“By utilising cutting-edge techniques, such the innovative CelVivo ClinoStar 2 System, we strive to gain insights into the safety and efficacy of underexplored medicinal plants in preserving cognitive function and slowing disease progression.

“By exploring the untapped potential of bioactive compounds found in medicinal plants and nutraceuticals, our research group aims to contribute to the identification of novel therapeutic targets and the discovery of new avenues for intervention to improve the quality of life for individuals affected by age-related brain conditions,” says Dr Ntsapi.

The researchers, in collaboration with others in the UFS School of Clinical Medicine, will develop 3D cell-based models of the human cortex and hippocampus by utilising the CelVivo ClinoStar 2 System. This cutting-edge technology, housed in an easy-to-use CO² incubator, mimics ‘animal model-like’ conditions with low sheer stress, allowing scientists to generate cell-based models that closely resemble real-world conditions.

Dr Ntsapi explains that they will specifically focus on the technologies’ applications in studying age-related neurodegenerative disorders, such as Alzheimer’s disease. The potential impact of this research is immense, as it could contribute to the development of novel therapeutic strategies for combating the debilitating progression of neurodegenerative diseases, and ultimately improving the quality of life for affected individuals.

Hope for the research

“Our hope for this research is to significantly advance our understanding of neurodegenerative disease progression and to develop novel therapeutic strategies that can effectively combat these debilitating conditions. Ultimately, we aim to improve the quality of life for individuals affected by neurodegenerative diseases by preserving cognitive function and slowing disease progression.

“This research will contribute to the knowledge pool in this field, with the potential to lead to groundbreaking discoveries in the treatment of Alzheimer’s disease and other related disorders, potentially contributing to the policy guidelines on how these conditions are managed and treated,” she says.

The international partners from Denmark and the UK have made their expertise and facilities available to postgraduate students from the UFS, some of whom they are co-supervising.

Dr Ntsapi, who is passionate about exploring innovative solutions to address the gradual decline in normal brain function associated with aging, was this year one the university’s nominations for the prestigious 2023/2024 NSTF-South32 Awards, popularly known as the “Science Oscars” of South Africa.

Mineral named after UFS professor
2017-09-29

Description: Mineral tredoux Tags: International Mineralogical Association, tredouxite, Prof Marian Tredoux, Department of Geology, Barberton 

Tredouxite (white) intergrown with bottinoite (light grey),
a complex hydrous alteration product. The large host
minerals are nickel-rich silicate (grey), maybe willemseite,
and the spinel trevorite (dark grey).


More than five thousand minerals have been certified by the International Mineralogical Association (IMA). One of these minerals, tredouxite, was recently named after an academic at the University of the Free State (UFS). 

Tredouxite was named after Prof Marian Tredoux, an associate professor in the Department of Geology, to acknowledge her close to 30 years’ commitment to figuring out the geological history of the rock in which this mineral occurs. The name was chosen by the team which identified the new mineral, consisting of Dr Federica Zaccarini and Prof. Giorgio Garuti from the University of Leoben, Austria, Prof. Luca Bindi from the University of Florence, Italy, and Prof. Duncan Miller from the UFS. 

They found the mineral in the abovementioned rock from the Barberton region in Mpumalanga, in May 2017.

In the past, a mineral was also named after Marie Curie
With the exception of a few historical (pre-1800) names, a mineral is typically named either after the area where it was first found, or after its chemical composition or physical properties, or after a person. If named after a person, it has to be someone who had nothing to do with finding the mineral.

Prof Tredoux said: “As of 19 September 2017, 5292 minerals had been certified by IMA. Of these, 81 were named after women, either singly or with a near relation. Marie Curie is named twice: sklodowskite (herself) and curite (plus husband). Most of the named women are Russian geoscientists.”

Another way to assess the rarity of such a naming is to consider that fewer than 700 minerals have been named after people. Given that there are by now seven billion people on the planet, it means that a person who is granted a mineral name becomes one in 10 million of the people alive today to be honoured in such a way. To date, over a dozen minerals had been named after South Africans, three of them after women (including tredouxite).

It contains nickel, antimony and oxygen
The chemical composition of tredouxite is NiSb2O6 (nickel antimony oxide). This makes it the nickel equivalent of the magnesium mineral bystromite (MgSb2O6), described in the 1950s from the La Fortuna antimony mine in Mexico.  

“This announcement is of great academic importance: the discovery by the Italian team of a phase with that specific chemical composition will undoubtedly help me and my co-workers to better understand the origin of the rock itself,” she said. She also expressed the hope that it may raise interest in the Department of Geology and the UFS as a whole, by highlighting that world-class research is being done at the department. 

The announcement of this new mineral was published on the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification website, the Mineralogical Magazine and the European Journal of Mineralogy.
