Abstract:
Objective:To study the distribution characteristics of mineral elements in Gastrodia elata samples with different grades and specifications （variants） from diverse producing areas and their classification and identification evidences. Method:Fourteen mineral elements in 31 batches of Gastrodia elata samples of different grades and specifications （variants） from diverse producing areas were determined by atomic absorption spectrophotometry， Mo-Sb colorimetry， and curcumin colorimetry， and then subjected to correlation analysis （CA）， discriminant analysis （DA）， and principal component analysis （PCA）. Result:The content of K， N， and P in G. elata was the highest， enabling them to serve as the nutritional limiting factors affecting its growth. The G. elata samples could be identified by the variation trend of elements （K>N>P>Mg>Ca>Fe>B>Zn>Mn>Cu>Ni>Cr>Pb>Cd）. The comparison of G. elata samples from multiple producing areas showed that G. elata from Zhaotong has the highest P， Fe， and Cd content， that from Lijiang the highest K content， that form Luotian the highest Zn and Cr content， and that from Jinzhai the highest Cu and Pb content. The content of Mg， B， Pb， and Cr in G. elata f. elata was higher than that in G. elata f. glauca. It was found that the content of P， Cu， and Cd in commercially available G. elata products gradually increased with the decrease in the commercial grade， while that of Mg， Fe， B， and Ni mostly decreased. As revealed by CA， Fe was positively correlated with Mg， Cr， and B. The producing areas of G. elata samples could be effectively identified by DA with Cd， Pb， Cr， Cu， B， and Ni as the main variables， and the accuracy reached up to 85.71%. According to the PCA of mineral elements in G. elata f. glauca from Zhaotong， Yunnan Province， Fe， Cr， Mg， Cd， P， Mn， B， Pb， and Cu exerted a greater influence on G. elata. Conclusion:The determination of mineral elements in G. elata samples contributes to identifying their authenticity and origin due to the easy operation， accurate results， and good stability.
