Abstract
The composition of Homalomena occulta essential oil in the northern region of Vietnam was analyzed and determined by GC-MS. The main constituents of essential oils are Linalool, Terpinene-4-ol, Geraniol, α-epi-Muurolol, α-Cadino, (-) - Spathulenol, Terpineol, Sabinene, ... Under different light, dark and temperature conditions of 4ºC, 45ºC and the storage time changes in the composition of the essential oils are determined. Under the influence of light and temperature leading to the main Linalool compound, Terpinene-4-ol markedly declined during the period after 6 months of storage. On the other hand, some compounds Hotrienol, Terpineol, (-) - Spathulenol and α-epi-Muurolol tend to increase from 0.057% to 0.459%. Furthermore, the essential oil components showed minimal changes and remained of quality when stored at 4 ° C compared to 45 ° C conditions. Research results have shown that Homalomena occulta essential oil is a promising aroma, it is necessary to conduct many studies to increase the stability and quality of the essential oil when incorporated into the matrix of pharmaceuticals, cosmetics, and food.
