摘要:

北方地区黄芪栽培中存在品种选择模糊、采收期不明确导致药材品质不均的问题。为筛选适宜品种与最优采收期,以蒙古黄芪(AM)与膜荚黄芪(AG)为试验材料,系统测定不同生长年限(1~3年)下2种黄芪生长指标(根长、根粗、根鲜重、根干重)与药用成分(毛蕊异黄酮苷、刺芒柄花苷、毛蕊异黄酮、粗多糖)含量,追踪不同生长月份2种黄芪药用成分动态变化,结合主成分分析(PCA)综合评价不同生长年限黄芪药材品质。结果表明:(1)2种黄芪的生长指标与药用成分含量均随生长年限增加显著上升;3年生AM生长优势显著,其根干重较2年生增幅达250.37%,毛蕊异黄酮含量较1~2年生显著提升1197.56%~1533.58%,3年生AG的根干重较2年生显著增加193.78%,毛蕊异黄酮含量较1~2年生增幅达516.33%~522.50%。(2)3年生AM的根长、根鲜重、根干重及毛蕊异黄酮苷、刺芒柄花苷、毛蕊异黄酮含量均显著优于AG。(3)月龄动态显示,AM药用成分(毛蕊异黄酮苷、刺芒柄花苷、毛蕊异黄酮)呈“N”型变化,峰值出现于29月龄;AG的毛蕊异黄酮苷与粗多糖呈“M”型变化,峰值在28~29月龄。(4)PCA结果显示,3年生黄芪与1年生黄芪显著分离(累计贡献率80.340%),3年生AM药材产量及品质最高。综上,蒙古黄芪在北方地区的生长与品质表现均优于膜荚黄芪,第3年10月(29月龄)为最优采收期。本研究为北方地区黄芪优质高产栽培提供了科学依据,未来可结合多点试验与分子机制解析进一步优化技术方案。

Abstract:

To address the inconsistency in the quality of Astragalus caused by ambiguous cultivar selection and indeterminate harvesting periods in Northern China, this study aimes to identify suitable cultivars and determine the optimal harvest time. Using A. membranaceus var. mongholicus (AM) and A. membranaceus (AG) as experimental materials, we systematically evaluated their growth parameters, including root length, root diameter, fresh root weight, and dry root weight, as well as the contents of key medicinal compounds (calycosin-7-glucoside, ononin, calycosin, and crude polysaccharides) across different cultivation years (1 to 3 years). The monthly dynamics of these bioactive components in both Astragalus species were monitored. Principal component analysis (PCA) was subsequently employed to comprehensively assess the quality of Astragalus at different growth stages. The results indicated: (1) Both growth parameters and medicinal compound contents in the two Astragalus species increased significantly with cultivation years. The 3-year-old AM exhibited marked growth advantages, with its dry root weight increasing by 250.37% compared to 2-year-old plants, and its calycosin content showing a significant increase of 1197.56% to 1533.58% relative to 1- and 2-year-old plants. The dry root weight of 3-year-old AG increased significantly by 193.78% compared to 2-year-old plants, with its calycosin content rising by 516.33% to 522.50% compared to 1- and 2-year-old plants. (2) The root length, fresh root weight, dry root weight, and contents of calycosin-7-glucoside, ononin, and calycosin in 3-year-old AM were all significantly higher than those in AG. (3) Monthly dynamics revealed that the bioactive compounds (calycosin-7-glucoside, ononin, calycosin) in AM followed an “N”-shaped change pattern, peaking at 29 months. In AG, calycosin-7-glucoside and crude polysaccharides exhibited an “M”-shaped change pattern, with peaks occurring at 28-29 months. (4) PCA results demonstrated clear separation between 3-year-old and 1-year-old Astragalus (cumulative contribution rate: 80.340%), with 3-year-old AM showing the highest yield and quality. In conclusion, A. membranaceus var. mongholicus (AM) demonstrated superior growth and quality performance compared to A. membranaceus (AG) in northern regions, with the optimal harvest time identified as October of the third year (29 months of age). This study provides a scientific basis for high-quality and high-yield cultivation of Astragalus in Northern China. Future research could further optimize cultivation practices by incorporating multi-location trials and molecular mechanism analysis.
