Prof Motlalepula Matsabisa, a specialist in indigenous knowledge systems from the Department of Pharmacology at the University of the Free State (UFS), is part of a delegation with Prof Blade Nzimande, minister of Science, Technology, and Innovation (DSTI), to the Second Ministerial Belt and Road Science and Technology conference (BRT) in China. 

The conference is being held in Chengdu from 11-12 June 2025 and will gather representatives from state-level agencies, scientific academies, and innovation enterprises from countries involved in the Belt and Road Initiative, including members of the Association of Southeast Asian Nations (ASEAN) and the Shanghai Cooperation Organisation. The theme of the conference is “Together for Innovation, Development for All – Jointly Building a Scientific and Technological Innovation Community for the Belt and Road”. 

Prof Matsabisa, Research Director of the African Medicines Innovations and Technologies Development at the UFS, is the only person from a South African university to be invited by Prof Nzimande as part of this ministerial trip. Other members of the delegation include members from the minister’s department, CEOs and board members of agencies that report to the DSTI – namely Technology Innovation Agency (TIA), the National Science and Technology Forum (NSTF), Council for Scientific and Industrial Research (CSIR), National Advisory Council on Innovation, Human Sciences Research Council of South Africa, South African Council for Natural Scientific Professions, National Science and Technology Forum (NSTF), National Advisory Council on Innovation (NACI), South African National Space Agency and the National Research Foundation (NRF). 

As a guest professor at the Beijing University of Chinese Medicine (BUCM) in Beijing, Prof Matsabisa accompanied the delegation on a visit to the university where he has a longstanding relationship. The UFS has the only active university collaboration within the China-South African Science and Technology bilateral agreement.

 

Supporting around aspects of traditional medicine 

According to a statement on the South African government website, Prof Nzimande expressed the department’s intention to strengthen collaboration with the Beijing University and the Aerospace Research Institute of the Chinese Academy of Sciences, in the areas of indigenous knowledge systems and space science, respectively. The minister visited both the BUCM and the Aerospace Information Research Institute of the Chinese Academy of Sciences this week. 

“It is an honour to be part of the minister’s delegation given that I am the only person from a university amongst the agencies. The UFS is indeed very honoured to have been the only one identified to be in this ministerial trip. I am honoured to make connections with the decision-makers such as the chairperson of the board of TIA and the CEO of NSTF and all the other CEOs. It’s indeed an honour to share our work with people from NACI and the minister’s office at DSTI. This really could not have been a better opportune moment for me,” says Prof Matsabisa. 

According to him, he is there to support Prof Nzimande around aspects of traditional medicine as well as with his meeting with the Chinese Minister of Science and Technology during the signing of a letter of intent on traditional medicines including in the BRT conference where the minister will give a talk that will cover traditional medicines. Prof Matsabisa says he is looking forward to strengthening the relationships between the UFS and BUCM and China as well as sharing with the minister the joint projects and joint students from both institutions, hoping for continued support and funding.

“This trip has opened new opportunities. TIA has invited me and the UFS to be part of their new project on neurodegenerative diseases with Cuba. It was wonderful to hear that both the CEO and the chairperson of the board had already been briefed about me to be part of the project.

“It is also great to be present at the signing of the letter of intent on traditional medicine as it is important to know where the policies are heading.”

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
