Racemic (±)-F18 (10-chloromethyl-11-demethyl-12-oxo-calanolide A), an analog of nature product (+)-calanolide A, is a new anti-HIV-1 nonnucleoside reverse transcript inhibitor (NNRTI). A successful enantioseparation of (±)-F18 offering (R)-F18 and (S)-F18 was achieved by a chiral stationary phase prepared HPLC. Their absolute configurations were determined by measurement of their electronic circular dichroisms combined with modem quantum-chemical calculations. Further investigation revealed that (R)-F18 and (S)-F18 shared a similar anti-HIV activities, however, (R)-F18 was more potent than (S)-F18 against wild-type virus, K101E mutation and P225H mutation pseudoviruses.

Toxicogenomics (TGx) refers to a set of technologies that assess genome-wide responses after toxic agent exposure. Altered gene expression patterns that are caused by specific exposures reveal how toxicants may disrupt cellular processes and lead to side effects. Development and application of " omics" technology facilitate the toxicogenomic research which sharing and interpretation of the enormous amount of biological information generated in toxicologic field. In recent years TGx has been widely valued and successfully applied as an effective research tool to evaluate the toxic effects of traditional Chinese medicine (TCM). Here we reviewed current progress in the field of TGx and focused on its application in traditional Chinese medicine safety evaluation, especially in revealing the mechanism, finding potential toxic biomarkers and studying compatibility detoxification of TCM.

5.Studies on the cell growth, differentiation and terpene lactone accumulation in Ginkgo biloba cell suspension cultures.
Chinese Journal of Biotechnology 2004;20(3):445-449
To provide supports for Ginkgo biloba cell engineering for production of Terpene lactones (Ginkgolides and bilobalide), the cell suspension were established from calli induced from zygote embryos and stems of 30-day-old seedlings respectively. The relationship between cell growth, differentiation and the terpene lactone accumulation in these suspension cultures were investigated. HPLC determination indicated that, the ginkgolide B was found in the embryo derived cell suspension cultures at 0.044% of cell dry weight, and this result was the first time reported in this study. The accumulation of terpene lactone in the suspension cultures derived from both the embryo and seedling stems are effected by the level of the cell differentiation. The ginkgolide B was only found in small cell aggregates in the size smaller than 2mm, and the highest level of ginkgolide B was accumulated in cell aggregates in the size smaller than 1mm; however, the cell aggregates in the size bigger than 3mm could only produced bilobalide and ginkgolide A. In the same size aggregates of the suspension cultures the terpene lactone accumulation is strongly effected by the source of the explant. When the size of cell aggregates was in less than 1mm, the concentration of bilobalide, ginkgolide A and B in the cell suspension cultures derived from the embryos was 2, 1.4 and 0.56-fold, respectively, higher than that of cell cultures derived from seedling stems.

OBJECTIVETo investigate the protective effects of Yuyin Ruangan Decoction(YRD, traditional Chinese medicine) on experimental hepatic injury in mice.
METHODSThe mice were randomly divided into control group, model group and YRD low, middle and high dose group(n = 11). By ip injection of D-GalN, CCk or thioacetamide (TAA), three models of hepatic injury mice were established to investigate the effects of YRD through detecting the indexes of liver function in serum and, the content of antioxidant system in the hepatic tissue.
RESULTSYRD could decrease the content of alanine aminotransferase (ALT)and aspartate aminotransferase (AST) in serum and that of malonaldehyde (MDA) in the hepatic tissue, upregulate the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in the hepatic tissue. Furthermore, the above effects were dosedependent in a certain degree. CoNCLUSION: YRD has some protection effects on the model of experimental hepatic injury in mouse.

The survey of traditional knowledge related to Chinese materia medica resources is the important component and one of the innovative aspects of the fourth national survey of the Chinese materia medica resources. China has rich traditional knowledge of traditional Chinese medicine (TCM) and the comprehensive investigation of TCM traditional knowledge aims to promote conservation and sustainable use of Chinese materia medica resources. Building upon the field work of pilot investigations, this paper introduces the essential procedures and key methods for conducting the survey of traditional knowledge related to Chinese materia medica resources. The essential procedures are as follows. First is the preparation phrase. It is important to review all relevant literature and provide training to the survey teams so that they have clear understanding of the concept of traditional knowledge and master key survey methods. Second is the field investigation phrase. When conducting field investigations, survey teams should identify the traditional knowledge holders by using the 'snowball method', record the traditional knowledge after obtaining prior informed concerned from the traditional knowledge holders. Researchers should fill out the survey forms provided by the Technical Specification of the Fourth National Survey of Chinese Materia Medica Resources. Researchers should pay particular attention to the scope of traditional knowledge and the method of inheriting the knowledge, which are the key information for traditional knowledge holders and potential users to reach mutual agreed terms to achieve benefit sharing. Third is the data compilation and analysis phrase. Researchers should try to compile and edit the TCM traditional knowledge in accordance with intellectual property rights requirements so that the information collected through the national survey can serve as the basic data for the TCM traditional knowledge database. The key methods of the survey include regional division of Chinese materia medica resources, interview of key information holders and standardization of information.' In particular, using "snowball method" can effectively identify traditional knowledge holder in the targeted regions and ensuring traditional knowledge holders receiving prior informed concerned before sharing the information with researcher to make sure the rights of traditional knowledge holders are protected. Employing right survey methods is not only the key to obtain traditional knowledge related to Chinese materia medica resources, but also the pathway to fulfill the objectives of access and benefit sharing stipulated in Convention on Biological Resources. It will promote the legal protection of TCM traditional knowledge and conservation of TCM intangible, cultural heritage.
