    摘要 ( 352 )  
    A novel method, probe-melting curve method, has been established to increase the detection throughputs within one fluorescence
    channel. Besides using an asymmetric PCR assay, this method employs another specially designed probe with a 5′ terminus
    modification. The method has been demonstrated by detection of rotavirus as model system. The sensitivity of probe-melting
    curve method was proved to be equal to the conventional TaqMan real-time RT-PCR. And the experiment results were cross
    checked by agarose gel electrophoresis. The successful establishment of probe-melting curve method breaks numbers of
    fluorescence channels from the restrictions and enlarges the application fields of current real-time PCR instruments.

    摘要 ( 322 )  
    Panax ginseng has been used as a highly valued medicinal plant. To investigate the biochemical variables of mountain cultivated
    ginseng roots with different growth periods, five kinds of enzyme activities were measured, respectively. It was found that five
    enzyme activities were increased remarkably during the slow-growth period relative to the fast-growth period. The activities of
    AMY and ACP were significantly increased during the whole ginseng growth period. However, EST, ALP, CAT activities were
    not found changes during the slow-growth period. Enzymatic activities of AMY and ACP can be used as one of the intrinsic
    indicators to assess the quality of ginseng and identify the growth period of P. ginseng in the future.

    Study on the quality control of Shang-Ke Bone-Knitting Tablet (SKBT)

    摘要 ( 273 )  
    Shang-ke Bone-knitting tablet (SKBT) is widely used in China because of its excellent efficiency on bone-fracture healing, which
    is composed of 12 kinds of drugs. In order to improve and strengthen the quality control standards of SKBT, three drugs, Asterias
    Amurensis (hai xing), Olibanum (zhi ru xiang), Myrrha (zhi mo yao), were chosen because of their contributions to the efficacy
    of SKBT and were identified by thin-layer chromatography (TLC). The results showed that the TLC method we have developed
    was reliable, accurate, simple and easily operated. The method was appropriate to control the quality of SKBT. Except for the
    TLC part, a simple, rapid and sensitive high-performance liquid chromatography (HPLC)-UV method has been developed
    to simultaneously quantify three active saponins of Notoginseng Radix et Rhizoma (notoginsenoside R1, ginsenoside Rg1 and
    ginsenoside Rb1). Methodological investigation indicated that the developed HPLC assay could be readily utilized as a quality
    control and quantitative analysis method of SKBT.
