珍稀药用植物明党参呋喃香豆素成分累积分布研究

Accumulation and Distribution of Furanocoumarins in Rare Medicinal Plants Changium smyrnioides Wolff

采用HPLC法测定明党参不同器官、不同生长期中珊瑚菜内酯、5-羟基-8-甲氧基补骨脂素的含量。结果表明,明党参根、茎叶、花葶及果实均含有2种呋喃香豆素,2种呋喃香豆素总量,根中以6月为最高,为163.8467μg/g;茎叶以1月为最高,为606.1023μg/g;花葶以6月上旬(生长发育接近成熟时)为最高,为117.1185μg/g;果实以成熟期为最高,达1070.6326μg/g。提示明党参药用器官(根)和非药用器官(茎叶、花葶、果实)为天然呋喃香豆素优质药用植物资源,具有广泛开发利用的前景。

HPLC method was used to determine the contents of phellopterin and 5-hydroxyl-8-methoxy-psoralen in Changium smyrnioides Wolff collected from different organs and different periods of growth.The results showed that roots,stems,leaves,scapes and fruits of C.smyrnioides contain two furanocoumarins.In the roots,the total contents of two furanocoumarins were highest in June reaching 163.8467 μg/g.In the stems and leaves,the contents were highest in January reaching 606.1023 μg/g.In the scapes,the contents were highest in early June when the scapes were grown close to maturity reaching 117.1185 μg/g.Furanocoumarins in fruit of C.smyrnioides（to maturity） was the highest,and reached 1070.6326 μg/g.C.smyrnioides is a high quality medicinal plant resource for natural furanocoumarins,including the medicinal and the non-medicinal parts of the plant.It has great potential that is worthy for further exploration.
