Characteristic Analysis on Trace Elements from Hedysari Radix in Different Months / 中国中医药信息杂志

ABSTRACT

Objective To analyze the characteristic changes of trace elements from Hedysari Radix in different months;To provide references for the choice of the best harvest periods. Methods Trace elements of Hedysari Radix from different months (June, July, August, September, October and November) were determined by atomic absorption spectroscopy and analyzed by single factors analysis of variance, correlation analysis, cluster analysis and factors analysis. Results There was obvious significance between the contents of Cu and Co (P<0.05), and there was obvious significance among the contents of Fe, Ca, Mn, Zn, Mg, Cr, Na, Li, Ni and K (P<0.01). The results of correlation analysis showed that months had positive correlation with Cu, had a negative correlation with Fe, Na, Mn, Cr and Li contents, and had significantly negative correlation with Ca, Mg contents. Mn, Cr, Ni, K and Na were the characteristics of trace elements from Hedysari Radix in different months. The different months samples could be divided into two categories of June, July, August, September samples (Ⅰ) and October, November samples (Ⅱ). Conclusion There is close relationship between the contents of trace elements from Hedysari Radix and months. The information and metabolic patterns of trace elements from Hedysari Radix in June, July, August, September (immature) samples are close or similar;the information of trace elements in October, November (nearly mature or maturing) samples are close or similar. Study on harvest times of Hedysari Radix by trace element as an indicator is with certain rationality.
