摘　　要：以取自和龙市头道镇大阳沟栽培的5年生、8年生和18年生人参主根部位为材料,利用高效液相色谱法对不同栽培年限人参不同部位的皂苷成分进行测定,研究了不同年限人参中皂苷含量的变化。结果表明:随着栽培年限的增加,各部位皂苷含量均有所提高,且以须根提高的幅度最大,其次为芦头;而主根与侧根中的增加量较少。18年栽培人参的主根中皂苷含量达24.78mg/g,是5年生栽培人参的3倍,是8年生人参的2.55倍。因此,人参的栽培年限是皂苷含量增加的关键因素之一。To explore the changing of ginsenoside content in Panax ginseng of different cultivation periods, using 5, 8 and 18-year-old ginseng of Helong area as experimental materials, ginsenoside contents were determined by high performance liquid chromatography （HPLC）. The results showed that ginsenoside con- tent improved with increasing cultivation period. Ginsenoside content in fibrous roots of Panax ginseng was the highest, the next in the rhizome, those in taproot and lateral roots were not increased obviously. Ginsenoside content in taproots of the 18-year-old ginseng reached 24.78 mg/g which was 3-fold and 2.55- fold more than 5-year-old and 8-year-old ginsengs, respectively. Thus, cultivation period is one of the key factors for enhancing ginsenoside content of Panax ginseng
