摘要:
目的制定波棱瓜子质量控制标准含量上下限,以此确定波棱瓜子用于肝纤维化治疗的合理用量范围。方法本文采用中压制备色谱收集不含波棱甲素(herpetrione,PEDX)的阴性样品,加入不同剂量的PEDX,制备不同浓度梯度的PEDX系列样品溶液,建立PEDX系列样品HPLC指纹图谱,四甲基偶氮唑盐(thiazolylbluetetrazoliumbromide,MTT)比色法观察PEDX系列样品溶液对人肝星状细胞系LX-2细胞增殖的影响,并比较PEDX系列样品溶液与波棱瓜子提取物溶液的抑制率差异。结果(1)指纹图谱结果显示,不同浓度梯度的PEDX系列样品相似度良好;(2)PEDX系列样品能抑制LX-2细胞增殖,加入样品的剂量M与细胞抑制率I值呈现一定的"量—效"关系,确定了波棱瓜子中药效成分PEDX的最小有效用量为0.68mg,最大有效用量为8.2mg。结论波棱瓜子用于肝纤维化治疗的合理用量范围为3.27
Abstract:
ObjectiveTo develop the quality standards of Herpetospermum caudigerum, and determine the rational administration dosage range for treatment of liver fibrosis. MethodsNegative samples without herpetrione were collected using medium voltage preparation apparatus. Different amounts of herpetrione were added in the negative sample solution, antiproliferative effects of series of herpetrione sample solution against LX2 cells were evaluated by MTT assay in vitro, and a comparison of difference between series of herpetrione and extracts was performed. ResultsThere were great similarity among the series of herpetrione samples from the HPLC fingerprint. The samples showed remarkable antiproliferative effects against LX2 cells, and it showed a certain dosageeffect relationship between dosage of herpetrione samples and cell inhibition rate value. Therefore, we defined the minimum effective dosage of herpetrione in the Herpetospermum caudigerum was 068 mg, the maximum effective dosage was 82 mg. ConclusionThe rational administration dosage range of Herpetospermum caudigerum for treatment of liver fibrosis was 327~3942 mg.
