【摘要】：目的制備桂枝飲片標(biāo)準(zhǔn)湯劑,并進行質(zhì)量標(biāo)準(zhǔn)研究。方法依照標(biāo)準(zhǔn)湯劑的制備要求,制備15批桂枝飲片標(biāo)準(zhǔn)湯劑,以肉桂酸作為定量檢測指標(biāo),計算轉(zhuǎn)移率與出膏率,并建立其HPLC指紋圖譜分析方法。結(jié)果通過對15批桂枝標(biāo)準(zhǔn)湯劑進行測定,肉桂酸轉(zhuǎn)移率為56.93%~94.06%,出膏率為3.30%~9.40%;并用中藥色譜指紋圖譜相似度評價系統(tǒng)(2012A)軟件進行指紋圖譜分析,標(biāo)定了9個共有峰,確認4個,分別為原茶兒酸(1號峰)、香豆素(4號峰)、肉桂酸(6號峰)、桂皮醛(7號峰)。對15批桂枝飲片標(biāo)準(zhǔn)湯劑分別進行了相似度評價,其相似度均高于0.95。結(jié)論建立了桂枝飲片標(biāo)準(zhǔn)湯劑指紋圖譜,該方法精密度、穩(wěn)定性和重復(fù)性良好,具有一定的鑒別意義,可為桂枝配方顆粒的質(zhì)量控制提供參考。
[Abstract]:Objective to prepare and study the quality standard of Guizhi decoction. Methods according to the requirement of preparation of standard decoction, 15 batches of standard decoction of Guizhi decoction were prepared. The transfer rate and extract rate were calculated with cinnamic acid as the quantitative detection index, and the HPLC fingerprint analysis method was established. Results the results showed that the transfer rate of cinnamic acid was 56.93% and 94.06%, and the ointment rate was 3.30% 9.40%. The chromatographic fingerprint similarity evaluation system (2012A) was used for fingerprint analysis. Nine common peaks were calibrated, and 4 peaks were identified as crude tea acid (peak 1), coumarin (peak 4) and cinnamic acid (peak 6). Cinnamaldehyde (peak 7). The similarity of 15 batches of standard decoction of Cinnamomum Cinnamomi was evaluated, and the similarity was higher than 0.95. Conclusion the fingerprint of Guizhi decoction was established. The method has good precision, stability and reproducibility, and can be used as a reference for the quality control of Guizhi prescription granules.
