We prepared protoplasts from Salvia miltiorrhiza Bunge suspension culture cells. Then, the protoplasts' vitality and functions were tested by fluorescein diacetate staining method and Fluo-3/AM flourescent probe. The optimal condition of protoplast isolation was Cellulase R-10 1.5%, Pectinase Y-23 0.3%, Macerozyme R-10 0.5%, 40 r/min 12 h, 600 r/min 5 min, and the protoplasts yield was 1.1x10(6) cells/g FW, the vitality was more than 95% by using fluorescein diacetate staining method. It has been confirmed that calcium fluorescent probe Fluo-3/AM can be successfully loaded into protoplasts.

Garcinia, a kind of dry resin secreted by Garcinia hanburyi Hook. F. G., is a traditional Chinese medicine with various biological functions such as detoxification, anti-inflammatory, and anthelmintic activities. Recent studies suggest that garcinia has potential anticancer activity. Increasing evidences indicate that the main active monomer gambogic acid isolated from garcinia can inhibit the growth of various cancer cells. Neogambogic acid is an isolated compound with a similar chemical structure as gambogic acid. Preliminary studies show that the neogambogic acid can selectively inhibit the growth of various cancer cells, and has a broader antitumor activity and lower toxicity than gambogic acid. In this review, we summarize the advances made in the investigation of the anti-tumor effect of neogambogic acid in recent years.

Mammalian oocyte maturation and early embryo development processes are Ca(2+)-dependent. In this study, we used confocal microscopy to investigate the distribution pattern of Ca2+ and its dynamic changes in the processes of bovine oocytes maturation, in vitro fertilization (IVF), parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT) embryo development. During the germinal vesicle (GV) and GV breakdown stage, Ca2+ was distributed in the cortical ooplasm and throughout the oocytes from the MI to MII stage. In IVF embryos, Ca2+ was distributed in the cortical ooplasm before the formation of the pronucleus. In 4-8 cell embryos and morulas, Ca2+ was present throughout the blastomere. In PA embryos, Ca2+ was distributed throughout the blastomere at 48 h, similar to in the 4-cell and 8-cell phase and the morula. At 6 h after activation, there was almost no distribution of Ca2+ in the SCNT embryos. However, Ca2+ was distributed in the donor nucleus at 10 h and it was distributed throughout the blastomere in the 2-8 cell embryos. In this study, Ca2+ showed significant fluctuations with regularity of IVF and SCNT groups, but PA did not. Systematic investigation of the Ca2+ location and distribution changes during oocyte maturation and early embryo development processes should facilitate a better understanding of the mechanisms involved in oocyte maturation, reconstructed embryo activation and development, ultimately improving the reconstructed embryo development rate.

The extraction of active ingredient group, i.e., prim-o-glucosylcimifugin, astragaloside, and 5-o-methylvisammiosode from Yupingfeng powder with one-pot method was studied in this work. A HPLC method was used to determine the content of each active constituent mentioned above in the extract. The influences of extraction temperature, time, volume percent of ethanol in water and its amount added on the content and yield of active ingredient group were investigated by orthogonal test. The experimental results showed that the optimized extraction conditions were as follows: 1g of Yupingfeng powder was one-pot extracted for 4 hours at 80 degrees C with 90% ethanol as solvent, and the yield and content of active ingredient group were 0.16%, 0.53% respectively. The active ingredient group in Yupingfeng powder could be effectively one-pot extracted under the conditions above.
