Abstract:  Extracting the active substances from asparagus with SFE ,the paper investigated the effects of pressure、 temperature、time on extraction. According to orthogonal test, the optimum extraction conditions were obtained as follows: P=30MPa, T=75℃, t=1h. After the analysis on the extracting substances with HPLC / MS, the results showed that: Rutin of flavonoids was the main component of the extracts.

Key words: asparagus, SFE, HPLC, MS
