摘要:
以不同生境中的鱼腥草为研究对象,分析其形态特征及主要有效成分含量的差异。该文测定了不同生境下主要环境因子指标及鱼腥草的叶长、叶宽、株高、基径、生物量和含水量,用高效液相色谱法测定其各部分主要有效成分金丝桃苷、槲皮苷含量,并对测量结果进行单因素方差分析和相关性分析。结果表明:环境因子会对鱼腥草的形态建成及有效成分积累造成不同影响,适宜的光照强度有利于鱼腥草对有效成分的累积; 鱼腥草中有效成分的含量表现出叶>茎>根的规律。适宜的遮阴处理,既可避免强光照对鱼腥草生长的抑制,又可显著提高有效成分的含量,从而整体增加对鱼腥草有效成分的收益。
Abstract:
The influence of different habitats on the germ plasms of Houttuynia cordata,morphological characteristics and effective composition contents of H. cordata in different habitats were compared. The main environmental factor indexes under different habitats and leaf length,leaf width,individual height,stem base diameter,biomass,water content were measured. And the effective composition contents were determined by HPLC. The results were analyzed by one-way ANOVA statistical analysis and correlation analysis. The results showed that environmental factors had significant effects on morphological characteristics and effective composition contents of H. cordata in different habitats,the optimum light intensity would promote the accumulation of effective composition. The effect sequence of effective component in various parts of the H. cordata was leaf>stem>root. Proper shade could avoid the strong light that restrains the growth. It also significantly increased the content of effective components. The results would give some advice to increase the quality of the H. cordata.
