Polyphenols are a large groups of natural compounds widely distributed in variety of plants. They are known to have antioxidant properties with potential health benefits. Green tea and cocoa are the two most widely consumed beverages in the world. Various researches suggest that green tea and cocoa was found to prevent cardiovascular diseases, cancers and kidney stones. The present study is intended to profile the phenols and flavonoids content and to assess the antioxidative capacity in both cocoa and green tea. The results of the study have revealed that one serving of cocoa has higher amount of polyphenols than that of green tea. Hence cocoa froths with antioxidants than green tea and its consumption can improve general health.Keywords

Design of area and power-efficient high-speed data path logic systems are one of the most substantial areas of research in VLSI system design, The Carry Select Adder (CSLA) provides a good compromise between cost and performance in carry propagation adder design. However, conventional CSLA is still area-consuming due to the dual ripple carry adder (RCA) structure. In this paper, modification is done at gate-level to reduce area and power consumption. The Modified Carry Select-Adder (MCSLA) is designed for 8-bit, 16-bit, 32-bit and 64-bit and then compared with conventional CSLA respective architectures, this work evaluates the performance of the proposed designs in terms of delay, area, power, and their products by implementing in Xilinx fpga. This CSLA structures are implemented in booth multiplier in order to increase the efficiency of the booth multiplier.Keywords
