(Compositae). and its structure was elucidated on the basis of spectral and chemical methods. Aster saponin G is 3-0[α-L-arabinopyranosyl-(1→6)-β-D-glucopyranosyl]-2β,3β, 16α-trihydroxyolean-12-en-28-oic acid(asterogenic acid) 28-0-[β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranosyl] ester展开更多

Through versatile algorithm, single layer/raster CNN array is implemented by incorporating the proposed technique. Simulation results have been obtained, and comparison has also been carried out to show the efficiency of the proposed numerical integration algorithm. The analytic expressions for local truncation error and global truncation error are derived. It is seen that the RK-embedded root mean square outperforms the RK-embedded Heronian mean and RK-embedded harmonic mean.展开更多
