The extraction of oil from myrtle seeds by ASE extraction method was studied, and its physicochemical index, fatty acid composition and nutrient composition were analyzed. The results showed that the oil rate of myrtle seed was 7.5%. The relative density, refractive index, acid value, peroxide value, saponification value, iodine value and unsaponifiable matter content of the myrtle seed oil were 0.915 6, 1.474 7, 4426 mgKOH/g, 1.573 mmol/kg, 180.5 mgKOH/g, 135.0 gI/100 g and 4.5%, respectively. The myrtle seed oil contained 16 kinds of fatty acids, which mainly were linoleic acid, oleic acid, stearic acid and palmitic acid. The contents of unsaturated fatty acids and saturated fatty acids were 85837% and 14.175%, respectively. The myrtle seed oil was also rich in brassicasterol, campesterol, β-sitosterol, α-tocopherol, zeaxanthin and other nutrients. |
