摘要
为了探索贵州羊耳菊最适人工种植区及最佳药材采收时间,以不同产地、 不同生长年限、 不同采收期的羊耳菊全草为试材,采用恒温干燥法、 热浸法和HPLC法,测定了含水量、 浸出物含量,以及3,5-O-二咖啡酰基奎宁酸含量,比较贵州不同产地、 一年生与两年生、 开花前后的羊耳菊药材质量.结果显示,龙里和花溪产羊耳菊药材的含水量最高,安顺和罗甸产羊耳菊药材的浸出物含量最高,从江产羊耳菊药材的3,5-O-二咖啡酰基奎宁酸含量最高;二年生羊耳菊药材在含水量、 浸出物含量及3,5-O-二咖啡酰基奎宁酸含量较高;开花前羊耳菊药材的含水量和3,5-O-二咖啡酰基奎宁酸含量较高,但浸出物含量较低.表明三都、 惠水、 罗甸和从江为贵州省羊耳菊较适宜的种植区;生长年限长的、 开花前采收的羊耳菊药材质量较好.
In order to explore the best plantation area and harvest time of Inula cappa,Inula cappa whole plant of different habitats,different growth years and different harvest time was used as experimental materials,and the contents of moisture,extract,and 3,5-O-two caffeoyl quinic acid were measured by using constant temperature drying method,heat-dipping method and HPLC method.Also,the different regions of Guizhou,annual and biennial,before and after flowering Inula cappa material quality were compared.The results suggest that,the water content of Longli and Huaxi Inula cappa was the highest;the extract content of Anshun and Luodian Inula cappa was the highest,and the content of 3,5-O-two caffeoyl quinic acid of Congjiang Inula cappa was the highest.The contents of water,extract,and3,5-O-two caffeoyl quinic acid of biennial Inula cappa were higher.And after flowering,the contents of water and 3,5-O-two caffeoyl quinic acid were higher in before flowering Inula cappa,but the extract content was lower.Thus,the counties of Sandu,Huishui,Luodian and Congjiang in Guizhou province were suitable planting areas for Inula cappa,and the Inula cappa quality was better for long growth years and harvested before flowering.
