Free Flavonoids from Rhus retinorrhoea Steud, ex Olive

  title={Free Flavonoids from Rhus retinorrhoea Steud, ex Olive},
  author={Jaber S. Mossa and Essam A. Abdel Sattar and Mohamed Abou-shoer and Ahmed Galal},
The isolation of persicogenin [1], velutin [2] and (2S) 5,3',4' trihydroxy-7-methoxyflavanone [3] and homoeriodictyol [4] from Rhus retinorrhoea (Anacardiaceae) is reported. The antimicrobial activity of the isolated compounds was studied. [1] and [2] were found devoid of any antimicrobial activity while [3] and [4] had weak activity (MIC; 200 µg/ml against Streptococcus faecalis and 300 µg/ml against Staphylococcus aureus. Furthermore, the LC 50 of the pure compounds were determined using the… Expand
Biological Properties and Absolute Configuration of Flavanones From Calceolaria thyrsiflora Graham
