摘　　要：为了评价不同生长年限对人工栽培条件下宽叶羌活生物量和化学成分的影响,对甘肃主产区栽培的宽叶羌活进行调查采样,采挖2年生、3年生宽叶羌活鲜样,分别测定其根鲜重、根干重、主根长、主根粗等4个生物量指标,以及羌活醇、异欧前胡素、挥发油、浸出物、多糖、总灰分及酸不溶性灰分含量等。结果表明,3年生的根鲜重、根干重、主根长及主根粗较2年生均有所增长,且羌活总产量为2年生的2~3倍;3年生宽叶羌活单株有效成分总量大幅增加,主要有效成分相对含量多有下降,品质略差。In order to evaluate the effects of different growth years on biomass and chemical composition of Notopterygium forbesii under artificial cultivation,the investigation and sampling of broad-leaf of Notopterygium forbesi in main producing areas of Gansu Province were carried out.The Notopterygium forbesii were cultivated for two years and three years,then the excavation of fresh Notopterygium forbesii of two years and three years were measured its root fresh weight,root dry weight,root length,root thick four biomass index,and notopterygium alcohol,isoimperatorin,volatile oil,extract,polysaccharide,total ash,and acid insoluble ash.The results showed that the root fresh weight,dry weight,taproot length and crude root of the three-year old increased compared with those of the two-year old,and the total yield of Notopterygium forbesii was 2~3 times of that in two years.The total content of active ingredients in the three year old Notopterygium forbesii was significantly increased,however the content of each active ingredient decreased and the quality was slightly worse.
