Naturally occurring new iridoids and secoiridoids published during 2005-2008 are reviewed with available physical and spectral data: mp, [alpha](D), UV, IR, (1)H- and (13)C-NMR and plant source. The works on biological and pharmacological activity of naturally occurring iridoids and secoiridoids reported during 2005-2008 are also reviewed. Bioactivities(More)
The paper describes a new architecture for implementation of 8 × 8 FDCT (Fast Discrete Cosine Transform) using Distributed Arithmetic (DA). This proposed architecture combines both DA based approaches for distributed input vector and constant coefficients. The described Combined Distributed Arithmetic based DCT (CDA-DCT) architecture has been(More)
