## Abstract:7-O-glucoside. Complete NMR data of 6-hydroxy-7-methoxy-a-dunnione and 7-hydroxy-6-methoxy-a-dunnione were obtained in two different solvents. Hexane, ethyl acetate and ethanol extracts were screened for antimicrobial, antioxidant and cytotoxic activities. The antimicrobial activity was assayed against Staphylococcus aureus, S. epidermidis, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, C. parapsilosis, C. dubliniensis, and C. glabrata, using the microdillution method. All extracts were inactive (… Show more

“…Altogether, 35 jacaranones were isolated from 37 plant species; three-quarters of the compounds are monomers ( n = 26), and the others are dimers ( n = 9) ( Figure 2 and Figure 3 ). Although the best sources of jacaranones are Asteraceae species, certain species of the Acanthaceae [ 3 ], Bignoniaceae [ 1 , 2 , 37 , 38 , 39 , 40 , 41 ], Delesseriaceae [ 42 ], Gesneriaceae [ 43 , 44 ], Oleaceae [ 45 ], and Theaceae [ 4 , 5 ] families were also found to be sources of jacaranones ( Table 2 ). Among Asteraceae species, the genus Senecio is represented by 20 jacaranone derivative-producing plant species [ 36 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 ].…”
