| TITLE： | Qualitative and quantitative analysis of chemical compounds in 3 species of wild Veratrum from Inner Mongolia |
| 摘要： | 目的 对内蒙古3种野生藜芦（藜芦、毛穗藜芦、兴安藜芦）的化学成分进行定性和定量分析。方法运用高效液相色谱串联四极杆-静电场轨道阱高分辨质谱技术，通过查阅SciFinder、ChemSpider数据库和相关文献以及与对照品比对，鉴别藜芦、毛穗藜芦、兴安藜芦的化学成分。运用高效液相色谱法测定3种野生藜芦中虎杖苷、氧化白藜芦醇和白藜芦醇的含量。结果共鉴定出31个化合物，包括13个茋类、11个黄酮类、4个有机酸类、2个糖苷类、1个巴西苏木素类化合物；绝大多数化合物为其中2种或3种野生藜芦所共有，仅有2个黄酮类化合物山柰酚和木犀草素为兴安藜芦所特有。3种野生藜芦中虎杖苷、氧化白藜芦醇、白藜芦醇的总含量为6.618～11.292mg/g，总含量由高到低依次为藜芦、毛穗藜芦、兴安藜芦；虎杖苷、白藜芦醇含量最高的是毛穗藜芦，氧化白藜芦醇含量最高的是藜芦。结论3种野生藜芦中大部分成分相似，仅山柰酚和木犀草素为兴安藜芦所特有。虎杖苷、氧化白藜芦醇和白藜芦醇的含量在3种野生藜芦中存在较大差异。 |
| ABSTRACT： | OBJECTIVE To conduc t qualitative and quantitative analysis for the chemical compounds in 3 species of wild Veratrum（V. nigrum ，V. maackii ，V. dahuricum ）from Inner Mongolia. METHODS HPLC-Q-Exactive-MS/MS technology was used to identify the chemical components of V. nigrum ，V. maackii and V. dahuricum by consulting SciFinder ，ChemSpider database and related literatures and comparing with the reference substance. The contents of polydatin ，oxyresveratrol and resveratrol in 3 species of wild Veratrum were determined by HPLC. RESULTS A total of 31 compounds were identified ，including 13 stilbenes， 11 flavonoids，4 organic acids ，2 glycosides，1 brasilin. Most of the compounds were shared by 2 or 3 species of wild Veratrum， only 2 flavonoids kaempferol and luteolin were owned by V. dahuricum . The total contents of polydatin ，oxyresveratrol and resveratrol in 3 species of wild Veratrum were in the range of 6.618-11.292 mg/g，and the total contents of them in V. nigrum were the highest ，followed by V. maackii and V. dahuricum . The contents of polydatin and resveratrol in V. maackii were the highest ，and the content of oxyresveratrol in V. nigrum was highest. CONCLUSIONS Most of the components of 3 species of wild Veratrum are similar，only kaempferol and luteolin are unique to V. dahuricum . The contents of polydatin ，oxyresveratrol and resveratrol are significantly different among 3 species of wild Veratrum. |
