The present work reports the total aflatoxin and aflatoxin B1 levels in 62 food samples from Istanbul, Turkey. The total aflatoxin content in dried American cucumber, squash, tomato, okra and saffron samples was found to ...
Design and synthesis of novel organometallic complexes using boronated phenylalanine derivatives as potential anticancer agents
Drug design and discovery studies are important because of the prevalence of diseases without available medical cures. New anticancer agents are particularly urgent because of the high mortality rate associated with cancer. ...
Phenolic compounds from Trifolium echinatum Bieb. and investigation of their tyrosinase inhibitory and antioxidant activities
Two bischromones, 3,3--dimethoxy-2--oxychromone (1), 3,3--dihydroxy-2,2--oxychromone (2) and a biflavone, 5,7,4-,5 -,3-,4--hexahydroxy-3 --O-beta-glucosyl-3-,7 --O-biflavone (3) have been isolated from whole plant of ...
