NIR spectromneter for non-destruction measurement of oil contents in an integrated kernel of corn was manufactured. Using LED (light emitting diode) as the light source and six filters as the monochromator, the specifications of the instrument are compared with those of the commercial instruments. The regression coefficient, the standard error, and the(More)
A design of IIR digital filter based on DSP and SOPC technology was respectively conducted in this paper. Then design principles and implementation schemes were put forward, and the schematics of the hardware circuits as well as the software flow chart were given in detail. The experimental results indicate that the SOPC design has the advantages of(More)
Six new steroidal saponins, namely glauco-chinaosides A-F, and one known compound were isolated from the tubers of Smilax glauco-china. Their structures were elucidated by a combination of spectroscopic analysis and hydrolysis followed by spectral and chromatographic analysis. Compounds 1-7 were tested in vitro for their cytotoxic activities against four(More)
Ginkgetin is known to be an anticancer agent in many studies. However, its effectiveness in treating chronic lymphoblastic leukemia (CLL) remains unknown. The present study aimed to evaluate the effects of ginkgetin on the growth of the K562 cell line. The MTT assay was employed to examine the proliferation of K562, and a terminal deoxynucleotidyl(More)
