摘要(Abstract):

目的 :探索野生乌拉尔甘草地下部分生长分布特点及其与甘草酸含量之间的关系 ,为揭示甘草酸的积累规律以及科学利用和保护野生甘草资源提供理论依据。方法 :通过对单株野生甘草地下部分的解析调查以及不同器官、不同年龄、不同部位、不同粗度药材的甘草酸含量测定 ,系统地研究了野生甘草地下部分生长分布格局与甘草酸含量之间的关系。结果 :一株完整的甘草地下部分由种子根、不定根、水平地下茎和垂直地下茎以及吸收根组成 ;2年生以下水平地下茎的甘草酸含量较低 ;直径 0 .5cm以下的不定根甘草酸含量较低 ;水平地下茎和不定根与垂直地下茎之间甘草酸含量存在显著差异 (P <0 .0 5 ) ,而水平地下茎与不定根之间差异不显著。结论 :甘草以水平地下茎为纽带 ,将不定根、垂直地下茎和吸收根连接成 1个庞大的地下网络系统 ;其器官类型、生长年龄、根系粗度以及生长部位在一定程度上都影响着甘草酸含量的积累 ,不定根和垂直地下茎的分布格局影响着水平茎中甘草酸的分布。
Objective:To ascertain the relationship between glycyrrhizinic acid content and the underground part growth character of Glycyrrhiza uralensis and provide the theoretical evidence for wild resources protection and artificial cultivation method of G.uralensis. Method:Through the analytical investigation on the underground part of G.uralensis and analysis of glycyrrhizinic acid content in different organs, parts, ages, and diameter medicinal materials, the systematic study on the relationship between glycyrrhizinic acid content and the underground part growth character of glycyrrhiza uralensis was carried out. Result: The underground part of a G.uralensis seedling consisted of seed root, random root, horizontal underground stem, vertical underground stem and assimilating root. The glycyrrhizinic acid content in horizontal underground stem with the age below two years old or in random root with the diameter below 0.5 cm was low. The difference of glycyrrhizinic acid content among horizontal underground stem, random root and vertical underground stem was obvious, but the difference between horizontal underground stem and random root was not obvious. Conclusion:The horizontal underground stem was of G.uralnesis acts as a link that can connect random root, vertical underground and stem assimilating root, so that the whole underground part constructs one huge underground net system. The glycyrrhizinic acid accumulation is a effected by organ type, growth age, root diameter and grow position, and the distribution pattern of random root and vertical underground stem has influence on glycyrrhizinic acid distribution in horizontal underground stem.
