摘要(Abstract):

以全国市场抽验的不同程度硫熏白芍及课题组自制的不同硫熏时间白芍为样本,通过比较白芍的硫熏程度与其性状,芍药苷、芍药苷亚硫酸酯的含量及其指纹图谱的变化,评价硫磺熏蒸对白芍质量的影响。该研究采用《中国药典》方法评价了硫熏白芍的性状,测定了其芍药苷含量,用LC-MS分析了芍药苷转化产物,建立基于HPLC的白芍指纹图谱检测方法,并以相似度评价了质量差异。结果显示硫磺熏蒸使白芍颜色变白,特有气味消失,产生刺鼻酸气,并对芍药苷含量有显著影响,随硫熏程度加剧,芍药苷含量明显下降,部分转化为芍药苷亚硫酸酯,而且这种变化是不可逆的。指纹图谱也有明显变化。说明硫熏对白芍质量产生了严重影响,应严格限定白芍的硫熏工艺。由实验可见,可以通过测定芍药苷亚硫酸酯的含量来控制白芍的硫熏程度。
The samples of sulfur-fumigated Paeoniae Alba Radix acquired both by random spot check from domestic market and self-production by the research group in the laboratory were used to evaluate the effects of sulphur fumigation on the quality of Paeoniae Alba Radix by comparing sulfur-fumigated degree and character,the content of paeoniflorin and paeoniflorin sulfurous acid ester,and changes of the fingerprint. We used methods in Chinese Pharmacopeia to evaluate the character of sulfur-fumigated Paeoniae Alba Radix and determinate the content of aulfur-fumigated paeoniflorin. LC-MS method was used to analyze paeoniflorin-converted products. HPLC fingerprint methods were established to evaluate the differences on quality by similarity. Results showed that fumigated Paeoniae Alba Radix became white and its unique fragrance disappeared,along with the production of pungent sour gas. It also had a significant effect on paeoniflorin content. As sulfur smoked degree aggravated,paeoniflorin content decreased subsequently,some of which turned into paeoniflorin sulfurous acid ester,and this change was not reversible. Fingerprint also showed obvious changes. Obviously,sulfur fumigation had severe influence on the quality of Paeoniae Alba Radix,but we can control the quality of the Paeoniae Alba Radix by testing the paeoniflorin sulfurous acid ester content.
