粗糙龙胆地下器官龙胆苦苷和可溶性糖含量的动态研究

The study on dynamic of the contents of gentiopicroside and soluble sugars in under ground organs of Gentiana scabra

对两个栽培地点北安和呼兰产粗糙龙胆的主要有效成分龙胆苦苷的含量和可溶性糖含量进行了研究。结果表明 :龙胆苦苷含量随发育节律而波动 ,6月份虽然有一个积累高峰 ,但含水率高 ,不宜定为采收期 ,适宜采收期均应是花期和休眠期。可溶性糖含量相应在 6月份出现先低后高的趋势 。

In this paper the contents of gentiopicroside and soluble sugars in under ground organs of cultivated Gentiana scabra in Bei'an and Hulan has been studied. The results indicated that the content of gentiopicroside changed with the rhythm of development. The content of gentiopicroside is higher in early June, but the water contents was also higher. So it is unsuitable to harvest in this season. To harvest in flowering and dormancy period is the best. The content of soluble sugars decreased in early June and gradually increased subsequently. It accumulated more in later development period.
