| 摘 要： | 采用高效液相色谱(HPLC)法对青藏高原白刺、枸杞、沙棘果粉中的7 种水溶性维生素进行分析测定。结果表明：一次提取、分离可同测定7 种水溶性维生素的含量，加标回收率在88.0%～113.4% 之间，相对标准偏差在1.1%～9.0% 之间；3 种果粉的VC、VB1、VB2 含量差异显著，VC 含量高低顺序为沙棘果粉＞白刺果粉＞枸杞果粉，沙棘、白刺果粉VC 含量丰富，分别高达(18266.4 ± 201.1)、(1468.5 ± 24.6)mg/kg；VB1 含量高低顺序为枸杞果粉＞白刺果粉＞沙棘果粉；VB2 含量高低顺序为白刺果粉＞枸杞果粉，而沙棘果粉未检出VB2；VB6、VB12、烟酸、叶酸均没有检出。

| Abstract: | The contents of 7 water-soluble vitamins in fruit powders of Nitraria, wolfberry and weabuckthorn grown in Qinghai- Tibetan Plateau were determined by high performance liquid chromatography (HPLC). Results showed that the contents of 7 water-soluble vitamins were successfully determined simultaneously by sequential treatment of extraction followed by chro- matographic separation and the recoveries for spiked standards and the relative standard deviations were 88.0% - 113.4% and 1.1% - 9.0%, respectively.
