Gaertn. is a herbaceous perennial plant native to South Africa and commonly known as treasure flower. They were obtained from the Nursery of the Faculty of Agriculture, Minia University. This work consists of two parts: Part I: Phytochemical study including: Metabolomics analysis of the total ethanolic extracts and different fractions of different organs (leaves & stems) and roots of Z. elegans and the whole plant of G. rigens. Determination of total phenolic and flavonoid contents. Phytochemical screening, extraction, fractionation, isolation and identification of different constituents from the leaves and stems of Zinnia elegans Jacq. Part II: Biological study of Zinnia elegans Jacq and Gazania rigens (L.) Gaertn. including: • Study of some pharmacological activities: 1- Antioxidant activity. 2- Anti-infective activities such as anti-malarial, anti-tyrpanosomal, anti-leishmanial, antibacterial and antifungal activities. 3- Hepatoprotective and nephroprotective activities. |
