Artemisia argyi essence extraction method

Abstract

The invention discloses an artemisia argyi essence extraction method, which comprises following steps: step one, raw material preparing; step two, raw material grinding; step three, artemisia argyi leaf essence extracting; step four, artemisia argyi stem essence extracting; step five, extract purifying; and step six, detecting and packaging. Compared with a conventional extraction method, the provided extraction method has the advantages that the artemisia argyi leaves and stems are distilled separately, thus the stems are extracted more sufficiently; through distillation, the heavy metals inessence are reduced effectively; the bacteria in the essence are killed by high temperature, the essence purity is increased; moreover, the operation is simple, water is used to carry out distillation, and the essence does not contain any other solvent.
