In this study, four new lignan glucosides, named difengpiosides A-D (1-4), were isolated from the stem barks of Illicium difengpi, together with seven known compounds 5-11. Their structures were identified on the basis of spectroscopic analyses (1D and 2D NMR, HRESIMS, CD) and a comparison with literature data. All the compounds were evaluated for their inhibitory effects on lipopolysaccharide ...

Consider a two-body collision process . Raiman[1986] observed that the conventional qualitative approach to this problem amounts to suppressing the mass information, which becomes inadequate when one wants to determine the direction of the velocity of an abject after a collision . He resolved this by going back to the original algebraic equations, which have all the mass factors . He then proce...

In this study, we evaluate the olfactory responses of Mahanarva spectabilis adults to aqueous extracts from following non-host plants for pest insect: garlic (Allium sativum L.), rue (Ruta graveolens cinnamon (Cinnamomum verum J. Presl), lemongrass (Cymbopogon citratus Stapf.), clove (Syzygium aromaticum star anise (Illicium Hook.f), eucalyptus (Eucalyptus globulus Labill.), tobacco (Nicotiana ...

  Background: Medicinal plants synthesize a vast array of secondary metabolites that are important for human life. For medicinal purpose, antimicrobial activity of substances derived from plant extracts has been recognized for many years. Pimpinella anisum L. (Apiaceae) and Illicium verum Hook. f. (Illiciaceae) plant species, have been used for treatment of infectious diseases in Iranian tradit...

background: nonalcoholic fatty liver disease (nafld) includes a group of chronic liver disorders caused by irregular accumulation of fat in liver tissue. the current study aimed to evaluate chemical composition and the effect of fruit extract and essential oil of pimpinella anisum in experimental model of nafld. materials and methods: sixty rats were randomly divided into ten groups, six in eac...
