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。

摘  要：
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. Significant differences in the contents of VC, VB1 and VB2 were observed among the three fruit powders. The contents of VC and VB1 were decreased in the following order: seabuckthorn> Nitraria > wolfberry, and wolfberry > Nitraria > seabuckthorn, respectively. However, higher VB2 was exhibited in Nitraria fruit powder than in wolfberry powder, whereas no VB2 was detected in seabuckthorn powder. Moreover, fruit powders of seabuckthorn and Nitraria were abundant in VC with contents of (18266.4 ± 201.1) mg/kg and (1468.5 ± 24.6) mg/kg, respectively. In additions, no other water-soluble vitamins like nicotinic acid, pyridoxine hydrochloride, folic acid and vitamin B12 were also detected in the three fruit powders.
