Le Huy Hai
Abstract
Finding new materials for the aromatherapy industry is very important for essential oil projects. The purpose of this paper is to investigate the effect of rainy and dry season weather in South Vietnam on Elsholtzia winitiana Craib's oil and citral content in the southern Truong Son mountain range in Vietnam. By the method of fresh sampling, steam distillation takes essential oil and then analysis on high- resolution gas chromatography (HRGC) and the standard sample of citral . We have discovered Elsholtzia winitiana Craib of the Lamiaceae family growing wild at an altitude of 800-1400m in the Central Highlands of Vietnam, with a 65-72% citral content in the essential oil. We surveyed and found essential oils concentrated mainly on leaves with a weight of about 0.9-1.2%, flowers 0.15-0.23%, roots 0.1%. Citral content in essential oils is 65-72% in leaves, 4-6% in flowers. We have also discovered the content of essential oils and citral in it of Elsholtzia winitiana Craib wild growing changes according to the rainy season and dry season. The important conclusion we have is that during the dry season, Elsholtzia winitiana Craib plant has a higher content of essential oils and citral than in the rainy season. But during the rainy season, the plants grow well so they can give more essential oil. This is a precious raw material to get citral for the fragrance industry.
