Oils Extraction from Plant Seeds by Low Boiling-point Solvent

Low-boiling point solvent (propane) was used to extract oil from 3 plant seeds. High-grade oil were obtained after refining. Results showed that oil from Perilla seed contained 55% α-linolenic acid, 20% oleic acid, 12% linolenic acid. The refined oil from Lithospermum erythrorhizon Sieb. Et zucc seed contained 13.5% γ-linolenic acid, 31% α-linolenic, 12% oleic acid, 21.6% linolenic acid, thereby making this oil on top of seed oil regarding to γ-linolenic acid content. The refined oil from Suaeda salsa seed contained 70% linolenic acid, 11% oleic acid, 6% α-linolenic acid, therefore indicating the nutritional value of this seed oil.
