Process Optimization of Microwave-assisted Extraction of Volatile Oil of Scindapsus aureus and Chemical analysis by GC-MS
PROCEEDINGS OF THE 2016 5TH INTERNATIONAL CONFERENCE ON ADVANCED MATERIALS AND COMPUTER SCIENCE(2016)
摘要
To determine optimum extraction process of volatile oil from flower of Scindepus aureus and analyze its chemical composition. The essential oils were extracted from S. aureus by microwave-assisted extraction (MAE), distillation time, solid-liquid ratio. Microwave Power were investigated with extraction ratio of volatile oil as index, extraction technology of volatile oil from flower of S. aureus was optimized by orthogonal test. Chemical composition of the volatile oil was analized by gas chromatography-mass spectrometry (GC-MS). The amount of the components from essential oil were determined by normalization method. The essential oils were identified with WileyNist05 and Nist05 mass spectrum atlas. Optimal extraction process of volatile oil was as follows: solid-liquid ratio 1: 14. distillation time 4h and microwave power 700W. There were 45 components that composed of about 81.94% of the total essential from Scindepus aureus. by MAE oil and they were separated and identified. The study provided scientific basis for further exploration and utilization of S. aureus.
