Moazzami, A.A. 2006. Sesame Seed Lignans Diversity, Human Metabolism and Bioactivity. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-7147-8 Sesame seed has been an important oilseed since ancient times. It contains 25% protein and 50% oil. Sesame seed possesses many health promoting effects, some of which have been attributed to a group of compounds called lignans (sesamin, sesamolin, sesam...

ABSTRACT: Flaxseed (Linum usitatissimum) is the richest source of plant lignan secoisolariciresinol diglucoside (SDG). In mammals, including bovine, SDG converted to mammalian lignans enterolactone (EL) and enterodiol (ED) by action gastrointestinal microbes. There a great deal interest in promoting increased intakes humans’ diet due potential health benefits lignans, especially prevention card...

One new triterpene, 3beta-hydroxy-29-norcycloart-24-one (1), and four new lignans, caruilignans (2-5), together with six known compounds were isolated from the aerial part of Artemisia caruifolia BUCH.-HAM. ex TOXB. Their structures were determined by various spectroscopic means. Most of the isolated lignans were moderately cytotoxic to Meth-A cells with ED50 values of 5-10 microg/ml, but not t...

Effects of natural and structurally transformed lignans compared with stilbenes or stilbenoids on production of nitric oxide (NO) triggered by lipopolysaccharide (LPS) and interferon-γ (IFN-γ), tested under in vitro conditions using murine resident peritoneal macrophages, are reviewed. Relation between the molecular structure and immunobiological activity was investigated, and implication of su...

Lignans are a large group of chemical compounds found in plants. They have effects on enzymes, protein synthesis, cell proliferation, angiogenesis, growth factor and cell differentiation. In this study, inhibition effects of α-(-)-conidendrin, enterodiole, enterolactone, nordihydroguaiaretic acid, secoisolariciresinol and secoisolariciresinol diglucoside against carbonic anhydrase I and II isoe...

Phytochemical investigation of the whole plant of Commiphora mukul Engl. resulted in the isolation of two lignans, epiexcelsin (1) and 5′-demethoxyepiexcelsin (2) which are reported for the first time from this species. The structure elucidation of the isolated compounds was based on 1D and 2DNMR analysis and by the comparison with the published data. The lignans 1 and 2 showed significant inhi...
