目的 建立GJ-4 HPLC指纹图谱,并明确特征色谱峰的化学成分,测定主含有效成分藏红花苷-3的含量。方法 采用Phenomenex Gemini C18色谱柱(250 mm×4.6 mm,5 μm),以乙腈-0.1%甲酸水为流动相进行梯度洗脱,检测波长440 nm,建立GJ-4的HPLC指纹图谱,通过相似度软件对其进行相似度分析;对主要有效成分藏红花苷-3进行含量测定。结果 建立了GJ-4的HPLC指纹图谱,对17个主要特征峰进行明确的化学指认,20批GJ-4的指纹图谱相似度在0.939~0.994之间,藏红花苷-3的含量在0.200~0.683 mg/g之间。结论 该方法专属性强,准确度高,可作为GJ-4质量控制的有效方法之一。 |

OBJECTIVE To establish a HPLC fingerprint of GJ-4 (an effective fraction from Gardeniae Fructus) and to quantify the main component crocin-3. METHODS The experiment was carried out on a Phenomenex Gemini C18 column (250 mm×4.6 mm, 5 μm), eluted with ACN-water with 1‰ formic gradiently and determined at 440 nm wavelength. HPLC fingerprint chromatogram of GJ-4 was set up and quality of 20 batches of GJ-4 was evaluated by similarity assay. The major contents of crocin-3 was determined. RESULTS The HPLC fingerprint chromatogram of GJ-4 was been established, in which 17 compounds were identified. The similarity of 20 batches of GJ-4 was about 0.939 to 0.994, and the content of crocin-3 was about 0.200 to 0.682 mg/g. CONCLUSION The method established in this paper can provide a comprehensive reference for the quality control of GJ-4. |
