Abstract:
      The optimal conditions of solvent extraction of okra seed oil were studied, and the fatty acid composition of okra seed oil was analyzed by GC-MS. Effects of extraction solvent, solid-liquid ratio, extraction temperature and extraction time on the oil yield were discussed by single factor experiment. The optimal extraction conditions were determined by orthogonal experiment as follows：petroleum ether (boiling range 60-90℃) as extraction solvent, solid-liquid ratio (g/mL) 1∶10, extraction temperature 60℃, extraction time 5 h. Under the optimal extraction conditions, the okra seed oil yield was 16.22%. The main fatty acid compositions were linoleic acid (41.13%), palmitic acid (37.27%) and oleic acid (17.19%).
