目的:分析测定单味白芍饮片汤剂中的化学成分。方法:分别采集7批次白芍饮片、5批次白芍药材、5批次赤芍饮片制备所得汤剂的拉曼光谱,并进行初步谱峰归属,分析白芍饮片汤剂与白芍药材汤剂的拉曼光谱,对比白芍饮片汤剂和同属药物赤芍饮片汤剂的拉曼光谱。结果:白芍饮片汤剂拉曼光谱在637,783,847,981,1 091,1 128,1 336,1 458,1 636cm-1处出现9个拉曼信号。白芍药材汤剂拉曼光谱中的783,981,1 128,1 336,1 458 cm-15个拉曼峰同样存在于白芍饮片汤剂的拉曼光谱中,633,1 633 cm-1拉曼峰发生微小频移,而716,737,835,916,1 072,1 271,1 600 cm-1等拉曼峰消失。此外白芍饮片汤剂和同属药物赤芍饮片汤剂的拉曼光谱存在较大差异。结论:拉曼光谱可能为白芍药或其他中药汤剂提供一种快速的化学成分检测方法。
OBJECTIVE: To analyze and determine the chemical components in the decoction of Paeonia lactiflora. Methods: Raman spectra of 7 batches of Radix Paeoniae Alba, 5 batches of Radix Paeoniae Alba, and 5 batches of Paeonia Lactiflora Paeoniae Preparata were respectively collected and analyzed. The Raman spectra of Radix Paeoniae Alba were analyzed. The Raman spectrum of the decoction compared with that of the Paeoniae Decoction decoction and the same drug Paeoniae Decoction decoction. Results: Raman spectrum of Radix Paeoniae Alcara decoction showed 9 Raman signals at 637,783,847,981,1 091,1 128,1 336,1 458,1 636cm-1. Raman spectrum of 783,981,1 128,1 336,1 458 cm-Raman peaks in the white peony herb soup Raman spectrum also exist in the Raman spectrum of white peony soup decoction, 633,1 633 cm-1 Raman The peak shifts slightly, while the Raman peaks such as 716,737,835,916,1 072,1 271,1 600 cm-1 disappear. In addition, Paeoniae Decoction decoction and the same drug Paeoniae decoction of the Raman spectrum there is a big difference. Conclusion: Raman spectroscopy may provide a rapid method for the detection of chemical constituents of white peony or other traditional Chinese medicine decoction.
