21. Caryopristimerin, the First Example of a Sesquiterpene-Triterpene Homo Diels-Alder Adduct, and a New 29-nor-Friedelane from Roots of Salacia crassifolia
Two new compounds, caryopristimerin and 2α,3α,22β-trihydroxy-21-oxo-29-nor-friedelan-24-oic acid, were isolated from the hexane/ethyl ether extract of Salacia crassifolia roots. Caryopristimerin represents the first example of a homo Diels-Alder adduct of a sesquiterpene and a triterpene, and the new 29-nor-friedelane displays a highly oxygenated A ring w

22. Plant Extracts Display Synergism with Different Classes of Antibiotics
Abstract: One manner in which plant-derived compounds exert their antibiotic potential is the synergism, a positive interaction between two compounds. Studies indicate that the use of plant extracts combined with antimicrobials may promote a significant reduction of the minimum inhibitory concentrations of antibiotics for bacterial strains. This study aimed
