目的:测定人工栽培与野生夏枯草土壤及其植株各器官矿质元素含量,以期为该资源保护利用及GAP研究提供理论依据。方法:运用ICP-AES法测定栽培与野生夏枯草各器官及其土壤中磷(P)、钾(K)、钙(Ca)、镁(Mg)、钠(Na)、铁(Fe)、铜(Cu)、锌(Zn)、锰(Mn)、铝(Al)含量,并对测定结果进行分析。结果:栽培与野生夏枯草土壤及其茎、叶、果穗矿质元素含量存在显著差异;P,Cu含量大小顺序为果穗>叶>茎,Mg,Ca,Zn,Fe,Mn,Al元素以叶含量最高,果穗次之,茎最少,K,Na在茎叶中含量较高,其次为果穗;土壤与果穗中Fe元素含量呈极显著相关,与茎及叶呈显著正相关;土壤与果穗、茎及叶中Zn元素含量呈显著正相关;K元素含量在土壤及茎间亦呈显著正相关;栽培与野生品夏枯草各部位对P吸收有富集作用。结论:夏枯草药材与土壤中多数矿质元素含量无直接相关,主要通过选择性吸收调控药材中矿质元素含量。
OBJECTIVE: To determine the contents of mineral elements in cultivated and wild Prunella vulgaris and their organs, with a view to providing a theoretical basis for the conservation and utilization of GAP resources. Methods: The contents of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sodium (Na), iron (Fe) and copper in cultivated and wild Prunella vulgaris and its organs were determined by ICP- (Cu), zinc (Zn), manganese (Mn) and aluminum (Al) were determined. The results were analyzed. Results: The content of mineral elements in cultivated and wild Prunella vulgaris soil and its stems, leaves and ear had significant differences. The order of P and Cu content was: ear> leaf> stem, Mg, Ca, Zn, Fe, Mn, Highest in the ear, followed by the ear, least in the stem, K and Na were higher in the stem and leaf, followed by the ear. The content of Fe in the soil and the ear was significantly correlated with the stem and leaf, And leaf Zn content was significantly positive correlation; K element content in soil and stem also showed a significant positive correlation; cultivated and wild products Prunella various parts of P absorption enrichment. Conclusion: Prunella herbs have no direct correlation with the content of most mineral elements in soil, mainly through the selective absorption and control of mineral elements in medicinal materials.
