The invention relates to a method for extracting
palmitoleic acid from
sea buckthorn fruit oil. The method comprises the following steps that
saponification treatment is conducted on a
sea buckthorn fruit oil sample, and saponified
sea buckthorn fruit oil mixed fatty acid is obtained;
urea and a commonly-used
organic solvent are mixed and subjected to stirring refluxing to enable
urea to be completely dissolved, then the sea buckthorn fruit oil
mixed fatty acid is added, refluxing extraction is conducted for 30 min to 120 min, and cooling is conducted to
room temperature; suction
filtration is conducted rapidly after embedding
crystallization is conducted, the commonly-used
organic solvent in filtrate is removed,
urea in the filtrate is destroyed, and a
fatty acid sample is obtained; the
fatty acid sample obtained after urea embedding is conducted is treated, a light component with the average free
path length is separated on the conditions that the pressure ranges from 0.1 Pa to 0.2 Pa, the
distillation temperature ranges from 70 DEG C to 140 DEG C, and the feeding speed and the film scraping rotating speed are guaranteed to form homogeneous films, and
palmitoleic acid is obtained. According to the method for extracting
palmitoleic acid from the sea buckthorn fruit oil, the method is simple and convenient to operate, the content of obtained palmitoleic acid exceeds 80% of the total
mass of the product, the yield of palmitoleic acid can be greatly increased, and the vacancy of domestic palmitoleic acid products is filled up.
