The invention discloses a method for extracting
traditional Chinese medicine abelmoschus manihot seed
essential oil by using a squeezing method, and relates to the technical field of
plant essential oil extraction, and the method comprises the following steps: (1)
raw material pretreatment: selecting dried
abelmoschus manihot seeds, removing impurities, cleaning with clear water, and then
drying at a low temperature of 40-60 DEG C until the
water content is lower than 8%; the dried
abelmoschus manihot seeds are stir-fried in stir-frying equipment, the stir-frying temperature is controlled to be 120-180 DEG C, the stir-frying time is 20-40 minutes until the surfaces of the seeds are golden yellow, a double-squeezing technology combining mechanical squeezing and native squeezing is adopted, and the
essential oil extraction rate is remarkably increased; the stir-frying process parameters are accurately controlled, so that active ingredients in the seeds are effectively activated; the crushing
granularity is optimized, and the oil yield and the
oil quality are balanced; no chemical
solvent is added, so that the product is purely natural and high in safety; the essential oil is clear and transparent, low in
impurity content and stable in quality; active ingredients are completely preserved, and the medicinal value is high.
