摘要： 为比较分析不同生长年限及不同坡向红芪(Hedysarum polybotrys Hand.-Mazz.)产量和主要功效成分含量,以甘肃武都产红芪为材料,采用紫外分光光度法测定其黄酮含量,采用苯酚-硫酸法测定其多糖含量。结果表明:生长年限及坡向对红芪产量和品质均有显著影响。半阳坡栽培条件下,1～4年内,不同生长年限红芪产量和品质也不同;其中,2年生根干重、黄酮和多糖含量分别是1年生的4.41倍、1.26倍和1.26倍,3年生根干重、黄酮和多糖含量分别是2年生的1.36倍、1.53倍和1.14倍,4年生根干重、黄酮和多糖含量分别是3年生的1.22倍、0.91倍和1.01倍。2年生栽培条件下,阳坡红芪产量、黄酮和多糖含量分别是半阳坡的1.09倍、1.26倍和1.10倍;4年生野生条件下,阳坡红芪产量、黄酮和多糖含量分别是半阳坡的1.49倍、1.30倍和1.12倍。综合分析红芪栽培的产投效益及功效价值,该地区红芪生长年限应以3年为宜,栽培地以阳坡为宜。另外,红芪产量和品质与其根径、根长具有显著相关性,在生产中,红芪根径和根长可作为其等级分级的感观性依据。

Abstract: The yield and functional composition of Hedysarum polybotrys Hand.-Mazz. between different years and different slope aspects were compared and analyzed in the Wudu county of Gansu provice. Ultraviolet spectrophotometry was used to determine flavonoid contents combined with the phenol-sulfuric method to determine polysaccharide contents. Results showed that growth years and slope aspects had significant influence on yield and quality. The yield and quality of Hedysarum polybotrys cultivated in semi-sunny slopes was different between each tested year. The root dry weight and contents of both flavonoids and polysaccharides in the second growth year were 4.41, 1.26, and 1.26 times of that in the first growth year; the third growth year were 1.36, 1.53 and 1.14 times of that in the second growth year, and the fourth growth year were 1.22, 0.91 and 1.01 times of that in the third growth year, respectively. In the second growth year, the root dry weight and the contents of flavonoids and polysaccharides cultivated in sunny slope were 1.09, 1.26 and 1.10 times of that cultivated in semi-sunny slope. In the fourth growth year, the root dry weight and the content of flavonoids and polysaccharides natural growing in sunny slope were 1.49, 1.30 and 1.12 times of that natural growing in semi-sunny slope. Comprehensive analysis indicated that growth years and environment had significant effects on the yield and quality of Hedysarum polybotrys cultivated on Micang Mountain in the Wudu county of Gansu province, and the suitable growth years should be three years, the appropriate cropland should be sunny slope. In addition, there was significant correlation between the yield, quality and the root diameter, root length of Hedysarum polybotrys cultivated in semi-sunny slope. The root diameter and length of Hedysarum polybotrys can be used as a sensory basis to classify Hedysarum polybotrys Hand.-Mazz. in the actual production.
