Objective To study the optimum process for Suanzaoren granules,and to optimize the ethanol-extracting process for jujuboside A in Semen Ziziphi Spinosae.Methods With the extracting rate of jujuboside A as the index,HPLC was used to determine the content of jujuboside A in extracted solution and the extracting conditions were optimized by orthogonal design.Results The optimum extracting condition was adding 8 times amount of 70% ethanol and refluxing for 60 min,then adding 6 times amount of 70% ethanol,refluxing and extracting for 40 min(two times).Conclusion The optimized process is stable and highly efficient.

This article was aimed to study enhancing efficacy and reducing toxicity on anti-tumor from total flavonoids and total polysaccharides in Taxus mairei compatibility with taxol. MTT assay was performed to analyze the cell proliferation and apoptosis of 4T1, A549, MCF-7 tumor cells after treatment of total flavonoids and total polysaccharides in T. mairei combined with taxol at different concentrations. Isobolograms was used to investigate the behavior of combination therapy. Therapy experiments were conducted on ICR mice bearing S180 sarcoma. The tumor weight was measured to calculate inhibition rate according to uniform design. Blood cells indicators were detected by blood cell analyzer. The results showed that total polysaccharides and total flavonoids can enhance the inhibition effect on 4T1, A549 cells by taxol. Total polysaccharides can enhance the inhibition effect of taxol to MCF-7 in vitro, and S180 sarcoma-bearing mice in vivo. It reduced the toxic effects of anti-tumor effect of taxol in vivo. It was concluded that taxol can achieve the effect of enhancing efficacy and reducing toxicity through combining with total flavonoids and total polysaccharides in T. mairei.
