Direct analysis of essential oil has been performed for estimation of the elemental content in five different extracted essential oils from the leaves of different plants, namely, Mentha longifolia, Rosmarinus officinalis, Ocimum basilicum, Elletaria cardamomum, and Lavandula hybrida. A benchtop total reflection X‐ray fluorescence spectrometer with a maximum power of 40 W was used for this purpose. Fourteen elements have been quantified in most of the extracted essential oil samples, and their limits of detection were determined. The detected elements are P, S, Cl, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, As, Br, Ni, and Hf. The validity of the present method was demonstrated using a standard reference material of organometallic oil sample. Two extraction methods of essential oils from leaves of the mentioned plants are evaluated, namely, classical hydro‐distillation and microwave‐assisted hydro‐distillation. The quantitative elemental analysis of the extracted essential oils using the two extracted methods was studied and compared.

通过TXRF光谱法直接分析精油

已经为元素含量的估计从不同的植物,即叶片进行五种不同的精油中提取的精油直接分析欧薄荷迷迭香罗勒Elletaria豆蔻,以及薰衣草矮牵牛。为此,使用了最大功率为40 W的台式全反射X射线荧光光谱仪。在大多数提取的精油样品中,已对14种元素进行了定量,并确定了其检出限。检测到的元素是P,S,Cl,K,Ca,Cr,Mn,Fe,Ni,Cu,Zn,As,Br,Ni和Hf。使用有机金属油样品的标准参考物质证明了本方法的有效性。评价了从上述植物的叶子中提取两种精油的方法,即经典的水蒸馏和微波辅助的水蒸馏。研究并比较了两种萃取方法对萃取精油的定量元素分析。
