异硫腈酸盐是芥属蔬菜中典型的成分,具有化学防癌作用。由于菘蓝Isatis tinctoria L.叶中可能存在挥发性异硫腈酸盐,且对该植物中挥发性成分的研究鲜有报道,因此作者采用顶空固相微萃取(HS-SPME)和气-质(GC-MS)联用技术分析菘蓝叶中的挥发性成分。将3.5g样品溶于含5mL水的管形
Isocyanates are typical components of mustard vegetables and have a chemical anti-cancer effect. Because volatile isothiocyanates may be present in the leaves of Isatis tinctoria L., and the volatile constituents in the plant are rarely reported, the authors used headspace solid-phase microextraction (HS-SPME) and gas-plasma. (GC-MS) analysis of volatile components in indigo leaves. Dissolve 3.5g sample in a tube containing 5mL of water
