RESUMO
This paper describes the digital earth technology and its core technology-"3S" integration technology. The advance and promotion of the "3S" technology provide more favorable means and technical support for Chinese medicine resources survey, evaluation and appropriate zoning. Grid is a mature and popular technology that can connect all kinds of information resources. The author sums up the application of digital earth technology in the research of traditional Chinese medicine resources in recent years, and proposes the new method and technical route of investigation in traditional Chinese medicine resources, traditional Chinese medicine zoning and suitability assessment by combining the digital earth technology and grid.

AIM: To assay the level of ferulic acid in rabbit taking Siwu Decoction (Radix angelicae sinensis, Rhlzorna chuanxiong, Radix rehmanniae praeparata) and the influence result of the blood picture. METHODS: The level of ferulic acid in rabbit blood was measured with HPLC after medication and the blood examination was carried out. RESULTS: During the period of medication, the levels of red and white blood cells, hemoglobin, Fe, Zn and Cu increased, packed cell volume and whole blood low-shear viscosity decreased. CONCLUSION: Ferulic acid in Siwu Decoction might be one of effective constituents, promoting blood circulation and replenishing blood.
RESUMO
Object To establish the fingerprint spectrum of Coptis chinensis Franch. by HPCE. Methods The correlation relativity of retention time and peak area of each chromatographic peak in different batches of medicinal materials were explored respectively, and beberine was chosen as the reference to calculate the relative retention time and the ratio of peak area for each chromatographic peak. Results The correlation coefficients of relative retention time and the ratio of each chromatographic peak were all higher than 0.999 0 in different batches of medicinal materials. Conclusion The established fingerprint spectrum is stable and credible, and could be used as characteristic fingerprint spectrum for C. chinensis.

RESUMO
AIM: To compare the ligustilide content in Siwu Decoction and its ingredient herb. METHODS: To extract with SFE-CO 2 and to determine ligustilide with HPLC. RESULTS: Of the content of ligustilide, the highest in single herb, next in the mixture of Angelicae Sinensis Radix and Lignstic Rhizoma, the lowest in Siwu Decoction. CONCLUSION: When Angelicane Sinensis Radix and Lignstic Rhizoma were in compound preparation, the content of ligustilide became lower obviously.
