Webinar - Authentication of Essential Oils through Chiral GCMS
Title: Authentication of Essential Oils through Chiral GCMS
Duration: 58 minutes
Available On Demand
Essential oils are one of the growing commodity markets in the flavor fragrance and aromatherapy sector. Its demand is increasing since it has fewer side effects than synthetic medicines. Unfortunately, due to a lack of reliable instrumental techniques and strict government regulation, adulteration of natural products is rampant worldwide: adulteration impacts the therapeutic values of oils and a country’s economy. Tentatively 80% of commercially available, so-called “natural” essential oils are adulterated somehow. Chiral GCMS is one of the most useful and practical applications for the authentication of essential oils. Plants of the specific species from any origins produce the same enantiomeric ratios, which is a crucial indicator of authentication in essential oils. For example, lavender has 95% L linalool, whereas coriander has 84% D linalool, citrus has 99% D limonene, fir needle has 100% L-limonene. Even being the same physicochemical properties, they have distinctly different biological and organoleptic properties. The enantiomer of the same molecule at the same time can be harmless as well as toxic. A chiral GCMS analysis helps detect other species mixing or nature-identical synthetic compound addition in essential oils.
