The Effect of Lavender Essential Oils
on Collagen Hydrolysate

Abstract:

The aim of this study was to develop new natural compounds based on collagen hydrolysate modified with lavender essential oils. The essential oils were extracted by hydrodistillation from aerial parts of Lavender officinalis L. and Lavender stoechas L. subsp. stoechas with the yield of 3.0 and 3.6% respectively. The chemical composition determined by GC-MS analyses showed that fenchone (45.47%), 1.8 cineol (19.47%) and camphor (17.23%) were the main components for L. stoechas oil, while for L. officinalis, linalool (28.00%) linalyl acetate (43.96%) and camphor (5.94%) were found in high concentrations. The main groups of essential oils were identified also by FT-IR. Natural compounds with 75:25, 50:50 and 25:75 ratios (w/w) were prepared by collagen hydrolysate with 6000 Da and lavender essential oils. The modifications of collagen hydrolysate as a result of lavender essential oil interactions were determined by FT-IR. The results showed that L. stoechas essential oil was linked stronger on collagen due to higher content of ketones comparing with L. officinalis which is rich in alcohols and esters. The essential oils were bonded on side chain of amino acids from collagen hydrolysate. The new obtained compounds could be used as basic natural ingredients in medical, pharmaceutical and cosmetic fields, as they are products with added value, keeping the therapeutic properties of both collagen and essential oils. Keywords: L. officinalis and L. stoechas essential oils, collagen hydrolysate, GS-MS, FT-IR spectroscopy
