African Botanical Heritage for New Crop Development

African Botanical Heritage for New Crop Development

The African continent is rather poor in plant biodiversity when compared to other continents on
and around the equator. Nevertheless, lots of useful plant species have been domesticated from
Sub-Sahara Africa material. Ethnobotanical research offers the possibility to collect information
on the use and utility of wild plant species from traditional peoples often living in or close to a
challenging natural environment. This type of information then allows us to find new candidates
for domestication and subsequent crop development for income generation and increased food
security. The case of Gnetum africanum illustrates the practical implications of developing a lesserknown
species, and highlights the institutional problems that go together with niche crop development.
The latter are subsequently presented and discussed in extenso, and solutions proposed in a
second part of this review text.

More Than 50 Herbal Medicines Hold Possibility for Cancer Cure

More Than 50 Herbal Medicines Hold Possibility for Cancer Cure Researches explore the probability of some Chinese herbal medicines to be effective ingredients in making anticancer drugs. (Photo : Getty Images ) Medical experts and nutritionists have long acknowledged that fruits and vegetables contain anticancer properties. Mother Nature seemingly holds another key for cancer prevention and treatment . Chinese scientists learned that 57 kinds of medicinal plants commonly used in creating traditional Chinese medicine have anticancer components, reported Xinhua. Dai Shaoxing from the Chinese Academy of Sciences (CAS) in Beijing, however, said that additional research should be conducted to determine their full potential to cure cancer. The fruit of the medicinal plant Siraitia grosvenorii , for one, contains mogrosides, whose extract--the natural compound mogroside V--was tested for its antitumor effect and its probable capability to treat pancreatic cancer, accor...

Cytotoxicity of four Aframomum species (A. arundinaceum, A. alboviolaceum, A. kayserianum and A. polyanthum) towards multi-factorial drug resistant cancer cell lines

Cytotoxicity of four  Aframomum  species ( A. arundinaceum, A. alboviolaceum, A. kayserianum  and  A. polyanthum ) towards multi-factorial drug resistant cancer cell lines Background The search for natural products as potential cytotoxic agents has yielded promising candidates. However multidrug resistance (MDR) is still a major hurdle for patients receiving chemotherapy. In the present study, we evaluated the cytotoxicity of the methanol extracts of four dietary   Aframomum   plant species ( A. arundinaceum, A. alboviolaceum, A. kayserianum   and   A. polyanthum ) against nine sensitive and MDR cancer cell lines. We have also identified the bioactive constituents of   A. arundinaceum . Methods The cytotoxicity of the methanol extracts of the above plants was determined using a resazurin reduction assay. Chromatographic techniques were used to isolate the constituents of   A. arundinaceum. Results A preliminary experiment o...

Date palm, bitter kola, zobo top local herbal ‘cures’ for Yuletide blues

Date palm, bitter kola, zobo top local herbal ‘cures’ for Yuletide blues T 0 Comments Today is Christmas. The Yuletide is here again. The season is synonymous with over indulgence in alcohol, food and sex. Hangover, weight gain and sexually transmitted infections such as Human Immuno-deficiency Virus (HIV) become the order of the day. But scientists have validated bitter kola, date palm, zobo, grapefruit, among others as ‘cures’ for hangover and to prevent weight gain. They advise against unprotected sex and promiscuity, and recommend being faithful to one partner and the use of condom. CHUKWUMA MUANYA writes. THE temptation to drink and get intoxicated with alcohol is high especially during festive periods. The habit, however, comes with the resultant hangover.      Hangover is the experience of various unpleasant physiological and psychological effects following consumption of alcoholic beverages, which can last for more than 24 hours.    ...
