The ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to conduct the qualitative analysis of the monoterpene chemical components from Paeoniae Radix Rubra. Gradient elution was performed on C_(18) HD(2.1 mm×100 mm, 2.5 μm) column with a mobile phase of 0.1% formic acid(A) and acetonitrile(B). The flow rate was 0.4 mL·min~(-1) and the column temperature was 30 ℃. MS analysis was conducted in both positive and negative ionization modes using electrospray ionization(ESI) source. Qualitative Analysis 10.0 was used for data processing. The identification of chemical components was realized by the combination of standard compounds, fragmentation patterns, and mass spectra data reported in the literature. Forty-one monoterpenoids in Paeoniae Radix Rubra extract were identified. Among them, 8 compounds were reported in Paeoniae Radix Rubra for the first time and 1 was presumed to be the new compound 5″-O-methyl-galloylpaeoniflorin or its positional isomer. The method in this study realizes the rapid identification of monoterpenoids from Paeoniae Radix Rubra and provides a material and scientific basis for quality control and further study on the pharmaceutical effect of Paeoniae Radix Rubra.
采用超高效液相色谱-四极杆-飞行时间质谱联用仪（UPLC-Q-TOF-MS）对赤芍中的单萜类化学成分进行定性分析。在C18 HD（2.1 mm×100 mm，2.5 μm）色谱柱上进行梯度洗脱，流动相为0.1%甲酸（A）和乙腈（B）。流速为0.4 mL·min-1，柱温为30℃。采用电喷雾电离（ESI）源在正、负离子模式下进行质谱分析。使用Qualitative Analysis 10.0进行数据处理。通过标准化合物、碎片模式和文献报道的质谱数据相结合的方式实现化学成分的鉴定。从赤芍提取物中鉴定出41种单萜类化合物。其中，有8种化合物在赤芍中首次报道，1种被推测为新化合物5″-O-甲基-没食子酰芍药苷或其位置异构体。本研究方法实现了赤芍中单核萜类化合物的快速鉴定，为赤芍的质量控制和药效进一步研究提供了物质和科学依据。
