Biological Activities
Compounds
Conditions
Gazania rigens contains costunolide, a sesquiterpene lactone that provides significant therapeutic benefits. This bioactive compound allows the plant to treat anti-allergic, anti-diabetic, and anti-inflammatory conditions. Furthermore, costunolide derived from the plant serves as an effective agent to treat anti-cancer ailments. The plant also demonstrates medicinal utility through its ability to treat anti-microbial issues. These diverse properties highlight the extensive pharmaceutical potential of Gazania rigens.
Preparations
Gazania rigens is prepared as leaf explants and stem explants to test their individual callusing potential. Specifically, stem explants treated with 1.5 mg/L 2,4-D showed a higher induction percentage than leaf explants. Once the induction process is complete, Gazania rigens is prepared as callus to serve as the foundation for further growth. From this friable callus, Gazania rigens is prepared as cell suspension cultures to facilitate the study of biomass and costunolide biosynthesis. These various preparation methods allow researchers to optimize the production of valuable medicinal compounds.
Parts used
Gazania rigens is a versatile medicinal plant that offers significant potential for pharmaceutical development due to its bioactive compounds. In recent research regarding callus induction, both the leaf and stem of the plant were utilized as primary explant types. The study revealed that stem explants achieved a higher callus induction percentage of 90% when treated with specific concentrations of 2,4-D. Meanwhile, leaf explants demonstrated a strong capacity for callusing as well, reaching an 80% induction rate. By utilizing these different parts of the plant, researchers can more effectively establish cell suspension cultures to produce valuable costunolide.
