Fast analysis volatile compounds from Artemisia absinthium with nanoporous aluminum wire without using the chemical solvents

In this study, the efficiency of nanoporous on aluminum wires as fibers for headspace solid-phase microextraction (HS-SPME) of volatile compounds from Artemisia absinthium were investigated and compared with two anodized methods. Solid-phase microextraction (SPME) is based on the distribution of analytes between sample solution and a fiber coated with a stationary phase. Commercially available SPME fibers have a number of drawbacks including relatively low operating temperature (generally in the range of 240–280◦C), mechanical fragility, low stability in acidic or alkaline samples, less selectivity and swelling in organic solvents. The prepared fibers are durable with very good chemical and thermal stability which can be coupled to GC and GC/MS. A one at-a-time optimization strategy was applied for optimizing the important extraction parameters such as extraction temperature, extraction time, sample mass and added water. Compared with hydrodistillation(HD), HS-SPME, provide the advantages of a small amount of sample, timesaving, simplicity and cheapness. In this method determination the volatile compounds without used the chemical solvents. The proposed methods are environmentally friendly, because no toxic solvent is used. Low cost, high-temperature resistance, firmness, and long durability are the main advantages of these fibers that were used for analysis of volatile compounds of Artemisia absinthium. Compared with conventional HD method, HS-SPME/GC–MS is a simple, rapid, solvent-free and efficient method for the analysis of essential oils in Artemisia absinthium with low sample amount.
