Microwave-Assisted Preparation of Activated Carbon Modified by Zinc Chloride as a Packing Material for Column Separation of Saccharides.

Activated carbon, an amorphous carbon material with a high specific surface area and void fraction, is widely used as an economical adsorbent in many fields. In this work, a kind of new activated carbon composite for saccharide column separation was prepared by zinc chloride impregnating and microwave heating. The structural characterizations validate the increase in porosity and the specific surface area of the activated carbon as well as the change of the activated carbon crystallite lattice.

The antagonism between apigenin and protoapigenone to the PDK-1 target in Macrothelypteris torresiana.

Apigenin and protoapigenone that both have the activities against various cancer cell lines co-exist in Macrothelypteris torresiana, while the extracts of M. torresiana couldn't achieve the fine anti-tumor effects for the existence of potent anti-tumor compounds. This study disclosed an antagonism between the two compounds on the protein level to elucidate the paradox.
