Oil Extraction from Marigold

Tagetes erecta (cv.Mint marigold) is not only grown for ornamental purposes but also used for essential oil extraction. Essential oils are natural plant products which accumulate in specialized structures such as oil cells, glandular trichomes and oil or resin ducts. In present study, extraction of essential oil from marigold will be carried out through solvent extraction method by using two solvents, petroleum ether and n-hexane. Gas chromatography analysis will be carried out for quantitative and qualitative analysis of oil.
