The bioassay-guided chemical examination of the rhizomes of R. emodi resulted in the isolation of two new oxanthrone esters, revandchinone-1, revandchinone-2, a new anthraquinone ether revandchinone-3 and a new oxanthrone ether, revandchinone-4. Their structures were established based on

The global threat of tuberculosis demands the search for alternative antimycobacterial drugs. The present study examined roots and petioles from Rheum rhaponticum for antimycobacterial activity. Crude methanol extracts and eight phenolic compounds isolated by preparative column chromatography were

Objectives Rheum ribes L. is a perennial plant that belongs to the family of Polygonaceae, which is often used in traditional therapy because it possesses many bioactivities, such as antioxidant and antibacterial ones. Here we examined the effect of different R. ribes L. extracts on oxidative stress
