Quality and Chemical Composition of Organic and Non-Organic Vetiver Oil

Abstract

Vetiver oil (Vetiveria zizanoides) has been used as perfume materials, cosmetics, fragrance soaps, anti-inflammation, repellent, and insecticidal agents. Organic vetiver oil has higher economical value than non-organic vetiver oil and it has been regarded to be able to compete in the global market. Therefore, studies have been carried out using 1 hectare of land and the first generation of organic vetiver oil has produced 0.57% of yield, greater than non-organic (0.50%). The quality of organic and non-organic vetiver oil was analyzed by Indonesian Standard (SNI) parameter, pesticide residue test, chemical composition by GC/MS, and the appearance of vetiver root. In general, the result of organic and non-organic vetiver oil has fulfilled the national standard; the quality of organic vetiver oil was better than non-organic one. Physically, the appearance of organic vetiver root was better than non-organic vetiver root; organic vetiver root was denser, more appealing, and did not have any black spots. The pesticide residue of organic vetiver oil was lower than non-organic vetiver oil. Based on SNI test, vetiverol (oxygen compounds) in organic vetiver oil was higher than non-organic vetiver oil.

Effects of Heavy Metals on the Yield of Essential Oil From Vetiver Grass Cultivated in Mine Tailings Amended With EDTA and Arbuscular Mycorrhizal Fungi

“…52,53 The extracted vetiver grass roots oil retained its viscosity property and was light brown in color which is classified as a regular quality while clear yellow color normally indicates premium quality. 52,54 The freshly extracted vetiver grass essential oil had an earthy woody and sweet odor which correlates well with related research. 55 The presence of heavy metals in the soils have been reported to enhance the yield of essential oils by plants such as vetiver grass.…”

Optimisation of the Supercritical Fluid Extraction of Vetiver Roots

“…There is some reported work on the extraction of essential oil from vetiver [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16] but the amount of oil will vary from location to location for similar material, so it is important to test the material specifically for use in the proposed plant. In addition, it is necessary to identify optimal process condition to maximize output.…”

Simple Purification of Vetiver Oil by Multiglass Plate System for Quality Improvement

“…It mainly comprises of sesquiterpenes and sesquiterpene derivatives, of which vetiverols, their carbonyl compounds and esters are the main constituents. Their relative abundance normally establishes the oil quality [4,9].…”
