Essential Oil Compositions, Antioxidant Activities, and Procollagen Synthesis Abilities of Four Lavandula angustifolia Varieties.

BACKGROUND:Lavender is an essential commercial crop with multiple varieties grown in the Ili River valley. The lavender essential oils (LEOs) produced from various vary in quality. METHODS:This study evaluated the biological activity of LEOs from the four commonly planted Lavandula angustifolia cultivars (L.Angustifolia 'Xinxun-1'-'Xinxun-4') in Ili. The chemical composition, antioxidant activity, and effect on human skin fibroblasts were analyzed. RESULTS:Gas chromatography results, coupled with flame ionization detection and mass spectrometry of the LEOs, indicated the presence of linalool, linalyl acetate, geranyl acetate, and trans-β-ocimene as the significant components of the essential oils. All LEOs exhibited significant antioxidant activity, with Xinxun3 oil exhibiting the most vigorous activity. Xinxun2 showed the highest ferrous ion chelating activity and reducing power, displaying the most increased collagen regeneration activity. CONCLUSION:To our knowledge, this is the first report on the collagen regeneration ability of LEO from the Ili river valley and reveals Xinxun2 as a potential collagen regeneration promoter.
