高效液相色谱-质谱联用技术测定毛榛中的紫杉醇含量

Established method by reverse phase HPLC and electrospray ionization mass spectrometry (HPLC-ESI-MS) analysis and hazelnut extract trace of taxol. Through the research, seven mass spectrum characteristics of taxol compounds were contested, and the taxanes database was initially established. It was found that the paciltaxel contents were 23.65 μg·mL^-1 and 4.09 μg·mL^-1 in leaves and stems respectively. The paciltaxel contents in different parts of hazelnut was slightly different, which were 0.61, 0.23 and 0.35 μg·mL^-1 in hazel branch, leaf and leather. With these data it can quickly identify the known paclitaxel compounds in hazelnut extract, and can perform the unknown structure analysis to certain degrees. This analysis method is confirmed sensitive, reliable and fast.
