The variation of the berberine content in roots and stem bark of Berberis asiatica with altitude and edaphic conditions in the western Himalaya was estimated by HPLC. The comparative assessment revealed a significantly higher berberine content in roots than in stem barks. Moreover, the berberine content varied significantly with altitude and edaphic conditions both in root and stem bark samples. The populations growing at low altitude contained significantly more berberine than the ones growing at high altitude. Also the moisture and potassium (K) percentage of the soil significantly influenced the berberine content.
采用高效液相色谱法（HPLC）估算了喜马拉雅山西部地区海拔和土壤条件对小檗碱含量在根和茎皮中的变化。比较评估显示，根中的小檗碱含量明显高于茎皮。此外，根和茎皮样本中的小檗碱含量均随海拔和土壤条件的变化而显著变化。低海拔生长的种群所含小檗碱明显多于高海拔生长的种群。土壤的水分和钾（K）百分比也显著影响小檗碱含量。
