chemical composition, seasonal variability, and antifungal activity of lavandula stoechas l. ssp. stoechas essential oils from stem/leaves and flowers. | essential oils from the stems/leaves (l) and flowers (f) of lavandula stoechas l. ssp. stoechas growing wild in southern sardinia (italy) were extracted by hydrodistillation and analyzed by gas chromatography coupled with flame ionization detector and ion trap mass spectrometry. the major compound was fenchone, accounting for, on average, 52.60% in l and 66.20% in f, followed by camphor (13.13% versus 27.08%, in l and f, respectively). f essential oil yields (volume per dry weight) decreased fro ... | 2006 | 16756368 |
chemical composition and antioxidant, antimicrobial, and antifungal activities of the essential oil of achillea ligustica all. | the chemical composition of the essential oil from flowering tops of achillea ligustica all. was studied. samples were collected in different localities of sardinia (italy) and hydrodistilled both with clevenger-type and with simultaneous distillation-extraction apparatus. the yields ranged between 0.88 +/- 0.06 and 0.43 +/- 0.02% (vol/dry wt). the essential oils were analyzed by gc-ms, and a total of 96 components were detected. from a qualitative point of view, irrelevant differences between s ... | 2005 | 16366708 |
