摘要
为了确定阔叶十大功劳适宜的收获期及客观评价其质量,采用高效液相色谱法(HPLC)测定了不同采收季节阔叶十大功劳茎中3种生物碱(药根碱、巴马丁、小檗碱)含量,探讨阔叶十大功劳茎中生物碱的积累规律。结果表明:在3种生物碱中,药根碱所占的比例最高;8月采收的阔叶十大功劳茎中生物碱总量最高,其次是11月、4月,5月采收的生物碱总量最低。因此,以生物碱为质量评价指标的阔叶十大功劳宜在8月份采收。
The present study was conducted to determine the appropriate harvest period for Mahonia bealei and to evaluate its quality.The high-performance liquid chromatography（HPLC） method was used to measure the contents and study the accumulation trend of three kinds of alkaloids viz.,jatrorrhizine,palmatine and berberine in stem of Mahonia bealei,collected during different months.The results showed that amongst the three alkaloids,proportion of jatrorrhizine was the highest.Further,the total content of alkaloids in stem of Mahonia bealei was the highest when harvested in August,followed by November and April,and it was the lowest in May.Therefore,the suitable harvesting time for Mahonia bealei is found to be August in order to get the maximum alkaloids.
