The review aims to collate recent research results on the phytochemistry and pharmacological properties of indigenous species of Salvia in South Africa as a first attempt to provide scientific support for past and present local traditional uses. Expand
Dierama luteoalbidum: Liquid culture provides an efficient system for the ex situ conservation of an endangered and horticulturally valuable plant
An efficient and reliable protocol for the in vitro propagation of Dierama luteoalbidum, an endangered and horticulturally important plant, is described and all acclimatized plantlets formed corms after 6 months following the application of 1% (v/v) Kelpak — a seaweed concentrate. Expand

It is suggested that pomegranate fruit peel could be exploited as a potential source of natural antimicrobial and antioxidant agents as well as tyrosinase inhibitors. Expand
Micropropagation of Thapsia garganica—a medicinal plant
Application of antifungal agents to in vitro-derived plantlets as pre- and post-acclimatisation treatments during transplanting significantly reduced ex vitro mortality. Expand
Genetic alterations for increased coumarin production lead to metabolic changes in the medicinally important Pelargonium sidoides DC (Geraniaceae).
Production of key metabolites at significantly higher concentrations due to transgenesis and positive anti-bacterial activity exhibited by transgenic roots lends support to the idea of developing these clones as an alternative source that will allow for sustainable access to economically valuable secondary compounds of P. sidoides.

An efficient system for the production of clonal plantlets of the medicinally important aromatic plant: Salvia africana-lutea L.
The tissue culture of S. africana-lutea not only favoured rapid multiplication but was also characterized by seasonal in vitro flowering that was in synchrony with that of plants growing in the wild, making it highly attractive for implementation as an in vitro conservation strategy. Expand
Nitrogen supply and abiotic stress influence canavanine synthesis and the productivity of in vitro regenerated Sutherlandia frutescens microshoots.
In vitro shoot cultures of the medicinal plant Sutherlandia frutescens were used to study the impact of three abiotic stresses, primarily on l-canavanine synthesis, and it is concluded that a deeper understanding of the nutritional requirements for the agricultural crop management of S.frutescens is needed.

The effect of light and 2,4-D on anthocyanin production in Oxalis reclinata callus
The incubation of red and white callus cultures in the dark or at low-light resulted in the repression of red pigment accumulation, and the application of 2,4-D inhibited pigment production in thewhite callus and decreased anthocyanin accumulation in the red callus. Expand
