ABSTRACT
The content of elements in Pedicularis was determined by ICP-MS aftermicriware-assisted digestion. Recovery and RSD of the method is 95%-102% and 1.24%-2.18% respectively, and the method is rapid and precise. There is different Element content in Pedicularis from different places. There are some relations between altitude and content in different places. The result of Pedicularis can provide theoretical basis for medicine research.

The contents of six trace elements Ca, Mg, Fe, Mn, Cu and Zn in the medicinal materials of cultivated and wild Rhizoma et Radix Notopterygii vegetated in different months were determined by flame atomic absorption spectrometry (FAAS) with air-acetylene flame, and the feature of trace elements contents and their seasonal dynamics were analyzed using SPSS16.0 analysis software. The recovery rate obtained by standard addition method ranged between 96.33% and 105.25%, and the relative standard deviation was 0.84%-2.98%. This showed that the method had good precision and definition. The study indicated that there are abundant microelements in medicinal materials of cultivated and wild Rhizoma et Radix Notopterygii. The contents of Ca are both highest in the medicinal materials of cultivated and wild Rhizoma et Radix Notopterygii, and the contents of Cu element are lowest; the contents order is Ca > Mg > Fe > Mn > Zn > Cu; the seasonal dynamics of Ca, Mg, Fe, Mn, Cu and Zn had obvious regularity in the medicinal materials of cultivated and wild Rhizoma et Radix Notopterygii. It is concluded that the amount of six elements in wild Rhizoma et Radix Notopterygii are more than the cultivated; the data can provide reference for artificial cultivation of wild herbs.

In the present paper, the authors analysed 10 mineral elements in the roots of Rheum tanguticum collected from 30 different habitats. The mean concentration values of the 10 elements decreased as follows: Ca>Mg>K>Fe>Mn>Cr>Zn>Ni>Cu>Se. Ca, Mg, K and Fe were abundant in this herb. Most elements varied over a wide range depending on the different habitats. The mineral element data were evaluated by principal component analysis to reveal the distribution pattern of elements in root. Four principal components (K-Ca factor, Cu factor, Mg factor and Zn-Se factor) of plant elements were selected. The authors' study provided a new scientific foundation for further studies and general application of this Chinese herb.

The Anisodus tanguticus (Maxim.) Pascher is a Chinese traditional medicinal material and Tibet herb of local Qing-hai. The authors collected, tanguticus and wild Anisodus tanguticus (Maxim.) Pascher, and analyzed the contents of mineral elements such as K, Ca, Fe, Na and Mg by atomic absorption spetrometer, and P by 721 spectrophotometer. The results show that: samples in different places are all rich in Mg and Na while poor in P. At the same time, Ca has a negative correlation with other elements. Compared to the others, the amount of 4 elements is higher in wild Anisodus tanguticus is higher.

OBJECTIVE: To constitute HPLC fingerprint of the methanol extract from Swertia mussotii grown in Sichuan Province. METHOD: RP-HPLC, methanol and water including 0.02% acid as mobile phase, gradient elution, flow rate 1.0 mL x min(-1), the detection wavelength was 260 nm, temperature was 30 degrees C. RESULT: The RSD values of peak area and retention time of common peaks in precision, repeatability and stability were lower than 5.0%, respectively, similarity was over 0.805 in S. mussotii collected from 10 different habitats. CONCLUSION: All results above exhibit that this method is simple, practicable, and reliable as a standard method in controlling the quality of S. mussotii.
