采用十八烷基硅烷键合硅胶为填充剂的色谱柱（250 mm × 4.6 mm，5 μm），以甲醇和体积分数为0.1%的磷酸水溶液为流动相， 建立了高效液相色谱（HPLC）测定雀嘴茶中熊果苷质量分数的方法，该方法在0.349 ~ 402.788 μg/mL质量浓度范围内具有良好的线性关系，精密度、稳定性、重复性均较好，并优化了提取雀嘴茶中熊果苷的方法.这不仅为雀嘴茶中熊果苷的质量分数测定提供了可靠的分析手段，也为茶叶及其他植物性产品中的活性成分检测提供了新思路.

A chromatographic column （250 mm × 4.6 mm， 5 μm） with octadecylsilane - bonded silica gel as the filler was used， with methanol and a volume fraction of 1% phosphoric acid aqueous solution as the mobile phase， to establish a method for determining the mass fraction of arbutin in tea using high - performance liquid chromatography （HPLC）. The method demonstrates a good linear relationship within the mass concentration range of 0.349 to 402.788 μg/mL， with satisfactory precision， stability， and repeatability. Furthermore， the extraction method for arbutin in tea was optimized with respect to extraction procedures and solvents. This method not only provides a reliable analytical technique for determining the mass fraction of arbutin in tea but also offers new insights for detecting active ingredients in tea and other plant - based products.
