Review on Steam distillation: A Promising Technology for Extraction of Essential Oil

Abstract

Steam Distillation is a process used to recover the volatile compounds with high boiling point from solid or liquid,
using saturated or superheated steam. Steam distillation is the most common process for extraction of essential oils from
plants. The advantage of this method is that the volatile components can be distilled at temperatures lower than the boiling
points of their individual constituents and are easily separated from the condensed water. This paper focus on the study of
constituents of essential oil, effect of pH, potential of oil towards repellency and insecticidal activity, effect of different
parameters such as water to water ratio, extraction time, effect of antibiotic material. Supportive research has been
mentioned in this paper which use steam distillation for extraction of essential oil from various plant materials.
