Chemical investigation of the methanol crude extract dried flower buds Syzygium aromaticum (Myrtaceae) resulted in isolation seven known compounds; oleanolic acid (1), lignoceric (2), β-sitosterol (3), heneicosanoic (4), 5-hydroxy-7-methoxy-2-methylchromone (5), 5-hydroxy-7-methoxy-2,8-dimethylchromone (6) and vanillin (7). Their structures were elucidated using one-dimensional NMR spectroscopy...

to introduce ecologically safe acaricide, effects of essential oils derived from cuminum cyminum (cumin), syzygium aromaticum (clove), and mentha spicata (spearmint) were determined on tetranychus urticae at 25±1◦c, 65±5% rh and a photoperiod of 16:8 (l:d) hour. the essential oils extracted by hydro-distillation were characterized by means of gc and gc–ms. bioassays were performed by filter pap...
