Tanshinones, the main bioactive compounds of Salvia miltiorrhiza, are the diterpenoid pigments, multiple genes were proved to be involved in their biosynthesis in plants. CYP76AH1 is the initial P450 gene in the tanshinones biosynthetic pathway, its function has been validated by yeast expression and in vitroenzymatic reaction. In order to clarify the function of CYP76AH1 in vivo, in this study, we constructedthe RNA interference of CYP7AH1 in S. miltiorrhiza hairy root. The RNA interference vector with a hairpin structure was constructed using the Gateway technology, and then the interference fragment was integrated into the genome of S. miltiorrhiza mediated by Agrobacterium rhizogenes. Several highly CYP76AH1 interference S. miltiorrhiza hairy roots were obtained for further analysis.

Astragalus adsurgens seed is one of the most common adulterants of Astragali Complanati Semen in the market, whose morphological characteristics are very similar with A. complanatus seeds (Astragali Complanati Semen). Many identification methods have been reported, such as morphological identification, fluorescence method, ultraviolet spectrophotometry, TLC, HPLC, protein electrophoresis and so on, but there's no much about microscopic identification. In the present study, the morphological characteristics and microscopic characteristics of these two seeds were investigated, which could provide scientific evidence for the identification and classification of Astragali Complanati Semen. Our results showed that these two seeds were slightly different in the color and the appearance, but significantly different in the microstructure of the seed coat and the hilum, and the distribution of fat droplets in the cotyledon cells. So these microscopic characteristics can be applied for the identification of Astragali Complanati Semen.

A novel series of fingolimod analogues containing diphenyl ether moiety were designed and synthesized based on the modification of immunosuppressive agent fingolimod used in the treatment of multiple sclerosis. Compounds were evaluated in vivo for lymphopenic activity and heart rate affection. Most compounds showed moderate lymphopenic activity. It is worth noting that compounds 6c, 6d and 14c-14e showed considerable immunosuppressive activities comparable to fingolimod. And compound 14e had no effect on heart rate.
