摘要： A simple, inexpensive, and efficient method for separation and purification of the α-and β-forms of penta-O-galloyl-D-glucose (PGG) without the need for HPLC. The methods provided herein are useful for separation α-PGG or β-PGG from a mixture containing α-PGG and β-PGG and other chemicals. The method for separation of α-PGG from a mixture of α-PGG and β-PGG comprises the steps of: adding water to a sample containing 50% or more α-PGG and 50% or less β-PGG; mixing the PGG and water to dissolve the PGG; filtering out any undissolved particles; and allowing the filtered solution to stand undisturbed until crystals form.

摘要： A method to synthesize benzyl group protected alpha-pentagalloylglucose (α-PGG) and related compounds. The method comprises the steps of: suspending a highly reactive acylation agent and an acylating catalyst in a donor solvent; adding α-D-glucose or an analogue thereof to the mixture; reacting the mixture at room temperature for a time sufficient for reaction to occur; evaporating the solvent; taking up the residue in an appropriate solvent; filtering the residue and solvent mixture; and evaporating off the solvent.

摘要： The present invention discloses a base station system, including an indoor part and a remote RF subsystem (RRS). The indoor part includes a RIU, a CCU, a BBU, a GPSU and a local interface unit. The RRS includes a remote interface unit, a RF transceiver unit (TRU) and an antenna. The local interface unit and the remote interface unit are for signal intercommunicating between the indoor part of the base station and the RSS. The TRU is a RF transceiver module of the conventional RFU, for amplifying an analog RF signal from the remote interface unit and transmitting the signal to the antenna. By flexibly selecting between an optical cable and an If cable, the interface unit of the present invention provides a digital baseband remote manner and an IF remote manner. According to the structure of the base station of the present invention, the number of the base station sites and the network operating cost decreases; on the other side, since one base station may cover a cell by smart antenna with only one optical cable or IF cable, the difficulty in mounting is reduced.
