  •   Objective   To study the quality standard of Gardenia jasminoides and its effective parts.   Methods  TLC was used to identify Gardenia jasminoides and its effective parts. The heavy metals, harmful elements, and moisture in Gardenia jasminoides and its effective parts were examined. The content of Gardenia jasminoides and its effective parts was determined by high performance liquid chromatography.   Results  TLC method could be used to identify Gardenia jasminoides and its effective parts. The moisture content of Gardenia jasminoides and its effective parts were 8.4% and 3.2%, respectively. ICP-MS was used to determine the contents of five elements in Gardenia jasminoides and its effective parts simultaneously. There was a good linear relationship between arsenic, cadmium, copper, mercury, and lead in the range of 0~20, 0~10, 0~500, 0~5 and 0~20 ng/ml, respectively; The method detection limit of each metal element was 3.3×10−5~1.3×10−3 mg/kg. The relative standard deviation (RSD) of precision was 0.32%~0.82%. RSD values of each element content showed that the method had good repeatability. And the recoveries of arsenic, cadmium, copper, mercury, and lead were 103%~112%, 98%~99%, 98%~99%, 105%~106% and 100%~103%, respectively (n=3). The stability of each element was good within 8 h. The contents of the five elements were within the limits of the current edition of Chinese Pharmacopoeia. The standard curve equation of gardenia was Y=15860X+22543, r=0.9999, indicating that there was a good linear relationship of gardenia in the range of 20.16~322.6 μg/ml. The RSD of precision was 1.86%. RSD of the two samples were 2.38% and 2.60%, respectively, indicated that the method had good repeatability. The average recovery of Gardenia was 99.1% (n=6). The stability of the two solutions was good within 8 h. The contents of gardenia and its effective parts were 5.71% and 34.2%, respectively.   Conclusion  The research on the quality of Gardenia jasminoides effective parts was carried out based on the research on the quality of Gardenia jasminoides, and the results met the requirements. Therefore, the method established in this experiment could control the quality of Gardenia jasminoides and its effective parts simultaneously.

  • 栀子是茜草科植物栀子(Gardenia jasminoides Ellis)的干燥成熟果实[1],主要产地为江西省抚州市、河南省唐河县等,中医药应用历史悠久,是一种药食两用资源。其具有清热祛火、缓解心烦、消肿止痛、化痰止咳等功效,用于热病心烦、湿热黄疸、淋证涩痛、血热吐衄、目赤肿痛、火毒疮疡,外治扭挫伤痛[1]。近年来,国内外众多学者对栀子做了大量的研究,证明了栀子中含有环烯醚萜、单萜、二萜、三萜、黄酮类、有机酸和挥发性化合物等丰富的化学成分[2-4],具有抑制神经系统[5]、保肝[6-7]、抗氧化[8]、降血糖[9-11]、利胆[12]、镇痛[13-14]等药理作用,其中主要的有效成分为环烯醚萜苷类化合物。

    目前对于环烯醚萜苷类化合物的富集纯化主要以大孔吸附树脂为主[15-18],本课题组前期建立了一种用栀子果实制备总环烯醚萜苷的方法,并获得了国家发明专利授权(ZL200510026144.5)。此制备工艺得率高,成本低廉,为环烯醚萜苷类成分的研究及探索栀子的药效物质基础提供技术支持,对栀子及其有效部位的全面质量评价至关重要。

    栀子环烯醚萜苷类有效部位的质量控制指标与栀子药材相比,其重点在于薄层色谱鉴别、检查及含量测定,其中检查项包括水分、重金属及有害元素。中药在贮藏及保管的过程中,水分含量是影响药材质量及其性状的重要因素。水分较高可导致药材霉变或虫蛀,为微生物和害虫提供良好的生长繁殖条件,从而进一步影响其有效部位的质量。重金属污染是中药在生产、运输、贮藏过程中可能会出现的污染类型,而中药成分中的重金属污染主要包括铜、汞、砷、镉、铅等。现代科学表明,残留的重金属能够与人体中的酶蛋白牢固结合,对组织细胞的功能、结构产生不同程度的破坏。而用栀子果实制备总环烯醚萜苷时,有机化合物根据分子量大小可以经溶剂洗脱分开而达到除杂的目的,从而减少栀子有效部位中的重金属元素残留量。本研究采用大孔吸附树脂法制备栀子有效部位,选用电感耦合等离子体质谱法(ICP-MS)对栀子及其有效部位中残留的重金属元素进行测定,旨在为临床用药提供科学依据。

    目前,总环烯醚萜苷的质量控制方法中仅以紫外分光光度法测定其含量[19],缺少针对总环烯醚萜苷整体的质量控制标准,故本研究在栀子药材的质量控制基础上建立了栀子有效部位的质量控制标准。

    • 栀子为传统中药,其有效部位是从栀子果实的乙醇提取物中制备得到的环烯醚萜苷类化合物,是后续制备中药复方制剂的常用成分,建立并规范栀子有效部位的质量标准,可以保证其质量,为临床疗效提供保障。

      本实验对栀子有效部位进行薄层色谱鉴别、水分检查、重金属及有害元素检查、含量测定。水分、重金属及有害元素的含量直接影响到栀子有效部位的质量。环烯醚萜苷类成分易溶于水,水分含量过高时,在一定温度、酸度条件下,可能会产生颜色变化或沉淀。本文建立了电感耦合等离子体质谱法测定栀子有效部位中5种重金属元素的分析方法,通过线性、检出限、精密度、重复性、稳定性、加样回收率,对该方法进行考察,结果表明该方法准确度高、选择性好,可用于栀子有效部位中5种重金属元素的同时检测。

      本实验测得栀子药材的含水量为8.4%,栀子有效部位的含水量为3.2%。栀子有效部位中镉、铜、汞、铅4种重金属元素的含量较栀子药材明显下降,而栀子苷的含量则显著提高。经分析,栀子果实制备得到总环烯醚萜苷粉末时,在减压浓缩干燥过程中水分蒸发导致栀子有效部位的含水量下降;栀子果实粗提物经大孔吸附树脂纯化时,先以少量水洗脱去除杂质,减少了环烯醚萜苷类成分的损失,再以低浓度乙醇洗脱有效成分,减少弱极性杂质的洗脱量,进而提高纯度,使得4种重金属元素含量降低,栀子苷含量提高。

      本研究首次建立了栀子有效部位的质量控制方法,此方法重现性好、操作性强,能够有效控制栀子有效部位的质量,为全面控制中药复方制剂的质量和临床疗效提供依据。
