Abstract

Lavandula angustifolia Linn. (Lavender) is an important source of high-quality fragrance and possesses several pharmacological activities such as antianxiety, antidepressant and hypnotic. Because of its high market price and medicinal values, adulteration is very common with L. angustifolia essential oil. The aim of present study is to characterize essential oil and detect adulteration in it by ATR-FTIR method. L. angustifolia essential oil was isolated by the hydrodistillation method and characterized by GC/MS and FTIR. The authentic isolated essential oil of L. angustifolia was further adulterated by sesame oil (0, 5, 10, 20, 30, 40, 50 and 100% v/v) and analyzed by FTIR. The GC/MS analysis of essential oil of L. angustifolia yielded 74 compounds and linalyl acetate (39.28%), linalool (26.76%), and trans--caryophyllene (4.77%) were found as major chemical compounds. The ATR-FTIR results of isolated pure essential oil of L. angustifolia showed characteristic peaks of linalool and linalyl acetate, the major chemical components present in it. For detection of adulteration in L. angustifolia essential oil, different binary-mixtures of L. angustifolia essential oil with sesame oil (0, 5, 10, 20, 30, 40, 50 and 100% v/v) were analyzed, and the results of FTIR analysis shows very strong peaks in the range of 2800 to 3000 cm-1 and at 1739.31 cm-1 in case of adulterated mixtures compared to the pure essential oil of L. angustifolia. The proposed method was found a simple, economic, quick, reliable, and reproducible for the detection of adulteration in L. angustifolia essential oil.
