Ultrasonic Assisted Extraction Process Optimization of Malabar Spinach Seed Oil and GC-MS Analysis

摘要

This paper selects petroleum ether as an extraction solvent, use ultrasonic to assisted extraction of Malabar spinach oil, research of extraction temperature, ultrasonic power extraction, extraction time, solid-liquid ratio on Malabar spinach oil extraction rate by orthogonal, extract rate was used as the main criterion to determine the optimum process conditions. The results showed that: the optimum conditions was ultrasonic power 135W, extraction temperature 40°C, extraction time 25min, solid-liquid ratio 1:10. Identified 19 kinds of main ingredientby GC-MS analysis.
