Abstract:

Phytochemical analysis of both HEA1 and the crude plant extract showed the presence of phenolics, tannins and saponins. Saponins were the predominant secondary metabolites and were mostly abundant in the plant extract and to a lesser extent in the active compound. Steroidal saponins, tannins and phenolics were also detected in the plant extract, but only the phenolics were detected in the active compound. The results of the phytochemical analysis showed that those compounds that were not present in the active compound could be removed from the crude extract during the TLC purification process.

(Chemistry, Faculty of Applied and Computer Sciences), Vaal University of Technology.<br>Rhus leptodictya commonly known as a mountain karee belongs to the family Anacadeceae and has been used since antiquity in tradition medicine. In the present study antimicrobial and antioxidant potentials of the leaves of Rhus leptodictya were studied, followed by isolation of at least one active compound which showed antibacterial and antioxidant potentials. Extractions were performed based on the polarity of the solvent used. The solvents used were hexane, dichloromethane, ethyl acetate, acetone

MSc (Med) (Pharmaceutical Affairs), Faculty of Health Sciences, University of the Witwatersrand<br>Fifteen traditional medicinal plants, indigenous to southern Africa, that are used to treat various respiratory ailments were screened for their antimicrobial activity and their chemical profiles were documented. Acetone:methanol (1:1) extracts were prepared from the leaves, stems, roots, barks and thorns of the investigated plant species. The antimicrobial activity was determined against pathogens associated with respiratory conditions i.e. Moraxella catarrhalis, Bacillus cereus, Enterococc

However, the diversity and antimicrobial activity of this group of fungus are largely unknown. In present research, five leave samples, collected from mangrove plant Acanthus ilicifolius var. xiamenensis at Lesser Kinmen Island, located roughly 2 km from the southeastern coastline of China, were used to screen for bioactive metabolites producing endophytic fungi. Endophytic fungal strains were isolated by using agar-based culture

EBV establishes permanent infection in B lymphocytes, which is characterized by expression of latency-associated nuclear antigens (EBNA), integral membrane proteins (LMPs), and non-coding RNAs. EBNA1 is the only latent gene to be prevalently expressed in almost all EBV+ neoplasms, and dimeric EBNA1-mediated origin of plasmid replication (oriP) DNA episome maintenance is essential for EBV-mediated tumorigenesis.

Abstract:

Introduction: Dark spots appearing on the skin caused by hyperpigmentation results from the action of tyrosinase, an enzyme whose activity leads to the production of the skin pigment melanin. Extracts of the plant Glycyrrhiza glabra, also known as liquorice, are commonly used to treat a range of conditions including skin hyperpigmentation. This study aimed at isolating and identifying compounds in extracts from South African liquorice root and assaying these compounds as to their antioxidant activity, their ability to inhibit the tyrosinase enzyme and their level of cytotoxicity.
