Salvia miltiorrhiza is a highly valued traditional chinese medicine for the treatment of atherosclerosis-related disorders in china, such as cardiovascular and cerebrovascular diseases in China. The wilt disease is serious in the culture of S. miltiorrhiza. Wilt disease cause biomass of plant shoots and roots is lessened, active components are decreased. To solve these problems, we research the pathogen causing wilt disease of S. miltiorrhiza. The suspected pathogen is identified by morphology and etiological test. The identification was further confirmed by alignment the sequences of internal transcribed spacer (ITS) amplified by PCR. Our result show the wilt disease of S. miltiorrhiza mostly occurred in July and August, which is hot and wetter. The wilt disease rate of S. miltiorrhiza continuous cropping for one year in S. miltiorrhiz stubble is 10%, but the wilt disease rate of S. miltiorrhiza continuous cropping for three years in S. miltiorrhiz stubble is 60%-70%. The root rot of S. miltiorrhiz caused by the wilt disease, so the wilt disease was mistaken for the rot root in production. Morphological characteristics show the pathogen is Fusarium oxysporum. The sequence of ITS wes determined and found by BLAST shared 99% identity to that of F. oxysporum f. sp. cucumerinum. So it comes to the conclusion that the causing agent of wilt disease on S. miltiorrhiza belongs to F. oxysporum.

This research established an HPLC method for determination of six C-Glycoside flavones of warer-soluble total flavonoids from Isodon lophanthoides var. gerardianus (Benth.) H. Hara, and studied the antitumor activity of the warer-soluble total flavonoids. The HPLC system consisted of Kromasil 100-5 C18 (4.6 mm x 250 mm, 5 microm) column and a solution system of methanol, acetonitrile and 0.5% formic acid gradient elution at a flow rate of 0. 8 mL x min(-1) and the wavelength of detector was at 334 nm. The column temperature was 25 degrees C. The antitumor activity of water-soluble flavonoids was assayed using HepG2 cell as the tested cell. The linear ranges of vicenin II, vicenin III, isoschaftoside, schaftoside, vitexin, 6, 8-di-C-a-L-arabinosylapigenin were 0.25-2.53, 0.12-1.20, 0.37-3.69, 0.16-1.63, 0.19-1.92, 0.14-1.42 microg, respectively. The average recoveries (n = 6) were 99.6% (RSD 0.87%), 100.2% (RSD 2.0%), 99.6% (RSD 1.8%), 97.9% (RSD 1.5%), 98.8% (RSD 1.2%), 98.6% (RSD 1.2%), respectively. After exposure in 24, 48, 72 h, the total flavonoids showed inhibitory effect on the proliferation of HepG2 cells with IC50 as the evaluation index, the IC50 values of 1.89, 1.71, 1.51 g x L(-1), respectively. The method is quick, simple and accurate with good re- producibility, and can be used for determination of vicenin II, vicenin III, isoschaftoside, schaftoside, vitexin, 6, 8-di-C-a-L-arabino- sylapigenin in the warer-soluble total flavonoids from L lophanthoides var. gerardianus. The warer-soluble total flavonoids from L lophanthoides have inhibitory effect on the proliferation of HepG2 cells.

In this study, Actin, 18S rRNA, PAL, GAPDH and CPR of Artemisia annua were selected as candidate reference genes, and their gene-specific primers for real-time PCR were designed, then geNorm, NormFinder, BestKeeper, Delta CT and RefFinder were used to evaluate their expression stability in the leaves of A. annua under treatment of different concentrations of Cd, with the purpose of finding a reliable reference gene to ensure the reliability of gene-expression analysis. The results showed that there were some significant differences among the candidate reference genes under different treatments and the order of expression stability of candidate reference gene was Actin > 18S rRNA > PAL > GAPDH > CPR. These results suggested that Actin, 18S rRNA and PAL could be used as ideal reference genes of gene expression analysis in A. annua and multiple internal control genes were adopted for results calibration. In addition, differences in expression stability of candidate reference genes in the leaves of A. annua under the same concentrations of Cd were observed, which suggested that the screening of candidate reference genes was needed even under the same treatment. To our best knowledge, this study for the first time provided the ideal reference genes under Cd treatment in the leaves of A. annua and offered reference for the gene expression analysis of A. annua under other conditions.

As products of interaction of time and space, geoherbs, which are essential parts of Chinese Materia Medica, were characterized in different morphology, unique habitat, continuous and changeable sites. The main fields in molecular mechanism of geoherbs focus on: biodiversity and molecular identification, genetic different and evolutionary genetics, geo-variation and environmental adaptation, germplasm and aimed genus choosing, expression and control of functional gene, gene transfer and bio-safety evaluation. The main tasks are to discover the genetic variation at molecular level, ascertain the molecular characteristics of geoherbs and the effect of environment on gene expression of geoherbs, confirm the genetic factors attribute to the forming of geoherbs, and find out the genetic basis of geoherbs at individual level and population level, respectively. This paper pointed out that the essential of geoherbs is continuers quantities variation at population level, geoherb's populations are different in gene frequency with the others'; geohersm are quantitative trait loci (QTL) controlled by multi - gene or combination with multiple-gene and major gene at individual level. It is very important to pay more attention to the scale effect of geoherbs, refer the theories and methods of quantities genetic, and concern more about the interaction of environment and gene in geoherbs' molecular mechanism research.
