Reichb.ex Meissn. and Boenninghausenia sessilicarpa Levl.(two sources of Yi medicine Ebazema) and analyze the similarity between them. [Methods] The infrared fingerprints of powder of B. albiflora(Hook.) Reichb.ex Meissn. and B. sessilicarpa Levl. were measured, and the common peak rate and variation peak rate of six samples were calculated to establish the sequence analysis method of common peak rate. [Results] There was a very high common peak rate(≥81.3%) and a very low variation peak rate(≤15.4%) between S1 and S4 as well as S2 and S6. There was a low common peak rate between S1 and S3 as well as S3 and S4, and the common peak rate was 42.9% and 47.6% respectively. There was a low common peak rate(≤47.6%) and a high variation peak rate(≥100.0%) between S1 and S3 as well as S3 and S4. [Conclusions] The method is simple and convenient to operate, can quickly identify different parts used as medicine of B. albiflora(Hook.) Reichb.ex Meissn. and B. sessilicarpa Levl.(two sources of Yi medicine Ebazema), and provide a new method to judge whether the two are equivalent when being used as medicine and quality evaluation.展开更多
目的研究大黄标准汤剂的量值传递规律。方法制备23批大黄标准汤剂,建立标准汤剂及其原料饮片的HPLC指纹图谱,标定共有峰,采用四级杆飞行时间高分辨质谱(quadrupole time-of-flight mass spectrometry,Q-TOF-MS/MS)对共有峰进行鉴定,分...目的研究大黄标准汤剂的量值传递规律。方法制备23批大黄标准汤剂,建立标准汤剂及其原料饮片的HPLC指纹图谱,标定共有峰,采用四级杆飞行时间高分辨质谱(quadrupole time-of-flight mass spectrometry,Q-TOF-MS/MS)对共有峰进行鉴定,分别测定饮片和标准汤剂中8个结合型蒽醌(芦荟大黄素-8-O-葡萄糖苷、大黄酸-8-O-葡萄糖苷、大黄素-1-O-葡萄糖苷、大黄酚-1-O-葡萄糖苷、大黄酚-8-O-葡萄糖苷、芦荟大黄素-3-羟甲基-O-葡萄糖苷、大黄素-8-O-葡萄糖苷、大黄素甲醚-8-O-葡萄糖苷)、5个游离型蒽醌(芦荟大黄素、大黄酸、大黄素、大黄酚、大黄素甲醚)、4个鞣质类成分(没食子酸、儿茶素、表儿茶素、表儿茶素没食子酸酯)和1个二苯乙烯类成分[白藜芦醇4′-O-β-D-(6″-O-没食子酰)-葡萄糖苷(RGG)]的含量及标准汤剂出膏率,以共有峰传递数、成分转移率及出膏率为指标,分析大黄标准汤剂的量值传递规律。结果大黄饮片指纹图谱标定共有峰45个,其中40个传递到了标准汤剂,40个共有峰的成分均得到鉴定,其中8个结合型蒽醌、5个游离型蒽醌、2个蒽酮类成分、5个鞣质类成分、2个二苯乙烯类成分采用对照品比对确认。8个结合型蒽醌和5个游离型蒽醌合计的平均转移率分别为43.83%和11.03%,没食子酸、儿茶素、表儿茶素和表儿茶素没食子酸酯的平均转移率分别为233.00%、79.58%、303.18%和58.71%,RGG的平均转移率为68.89%,标准汤剂平均出膏率为23.26%。结论研究结果为大黄配方颗粒和含大黄经典名方制剂工艺研究和质量评价奠定了基础。展开更多
